How to Choose the Perfect Wi-Fi Router

The key to a connected home is the connected part. A smart device without the wireless communication features is just a regular old device! Some smart devices communicate through Bluetooth, but the vast majority connect through Wi-Fi. Therefore, the Wi-Fi router is one of the most important components of a smart home!

Sometimes your internet service provider offers to have you rent a router. This is usually a bad deal. You can often save money by buying your own router. Read on to find the right router for your home.

Router Speed

There are several different classifications of router speeds, denoted as 802.11 followed by a letter. The Wi-Fi speed ranks go like this: a -> b -> g -> n -> ac, with “a” being the slowest, and “ac” being the fastest.

If you’re in the market for a new router, beware 802.11a, 802.11b, or 802.11g routers. These routers are several years out of date, and unless you’re getting them for rock bottom dollar, they are not worth the money.

802.11n routers tout speeds up to 300 megabits per second, and 802.11ac routers can reach speeds around 1300+ megabits per second. Now keep in mind, the maximum speed you will get depends on the internet service you pay for. Most modern homes do not have access to speeds faster than 300 megabits, so you would likely be okay with purchasing an 802.11n router. However, if you want to be future-proof, purchasing an 802.11ac router should have you set for the next several years.

Dual Band vs. Single Band

Many routers offer dual band functionality, such as 2.4 ghz signals and 5 ghz signals. Single band routers only offer 2.4 ghz signals. If you have a lot of devices or really need the extra speed, go for the dual band router. If your router use will be modest, you can save some money and stick with the single band.

Extenders and Mesh Networks

If you have a large home, you may need to purchase Wi-Fi extenders. These devices can boost the signal and reach further rooms in the house. I recommend setting up your new router first to see if extenders are necessary.

If money is no object, you could purchase routers with mesh networking technology. These routers automatically work together to create a powerful Wi-Fi network. The technology is mostly used in commercial buildings, but is now becoming more accessible for the consumer. That being said, mesh routers can be very expensive!

All About Computer Networks

All About Computer Networks

Over a period of time, computers have become an indispensable part of businesses. Installation of computers, their support and maintenance are services all organizations require. As businesses grow, the number of computers in the organization also increase. It becomes imperative to establish a systematic way to connect these computers so that they function in a hassle-free manner. Therefore, computers are interconnected in various ways. This is the concept of a computer network.

What is a computer network?

A computer network can be understood as a number of computers connected together to share resources. The most common resource shared is the internet. Other resources can be printers, file servers, etc. The computers in the network may be connected through an Ethernet cable or wirelessly through radio waves. 
Now we will see how the individual computers in a network are connected: 
Computers connected in a network are referred to as nodes.

Star Topology:

In this case, there is a central node from which connections are provided to individual computers. In this case, even if there is any problem with a particular cable, the other computers can continue to function undisturbed. On the flipside, this type of connection requires a lot of cabling.

Bus Topology:

In this case, all the computers are connected by a single cable. The information that is intended for the last computer needs to travel through all the nodes. The chief benefit is that it requires minimal cabling. However, if there is any fault in the cable, all the computers are affected.

Ring Topology:

In this topology, all the computers are connected through a single cable. The end nodes are also connected to each other. The signal circulates through the network to reach the intended recipient. In case, a network node is configured incorrectly or there is some other issue, the signal will make numerous attempts to find the intended recipient.

Collapsed Ring Topology:

In this case, the central node is a network device known as the hub, router or switch. This device runs in a ring featuring plugins for cables. And, each computer is independently connected to the device through individual cables.

Each organization chooses its own topology of the computer network to ensure a streamlined functioning of their computers. Once the computers are connected, offices also have separate cabling closets, which is essentially a space containing a switch device that connects to the network.

There are a number of computer network companies that provide the services of installation, maintenance, and support services ensuring smooth and streamlined functioning of your systems.

Looking Beyond the Most Common Application of PET Scan – Oncology

Looking Beyond the Most Common Application of PET Scan – Oncology

More often than not the PET scan technology is utilized to detect the presence of a brain tumor. But there is more to the tool than just recognizing Cancer. It can be used for:

  1. Internal injuries
  2. Bleeding in brain
  3. Infection detection
  4. Structural abnormalities inside the skull

Though a powerful invention, the device has limitations which means at times, a pet scan brain tumor test is inclusive. In such circumstances, other medical tests are conducted such as X-Rays for a final diagnosis. But for the purpose of this writeup, we focus on only scanning technologies.

The Two Broad Types of Brain Scans

When loosely categorized there are only two kinds of technologies that can be used to scan the brain:

  1. computed tomography (CT)
  2. magnetic resonance imaging (MRI)

Within these two classes, there are numerous variations. Each kind is applied to detect and diagnose a different type of medical problem which device is wielded is dependent upon the symptoms the patient faces.

6 Varieties of Brain Imaging Tools

Every brain imaging technique has the same goal – to search for problems that are happening inside the brain of a patient or view its activity. At present, there are six most often used methods to conduct the process.

  • CT scan resorts to X-Ray for creating a picture of the brain. The actual device is a cylindrical apparatus which a sliding table on it. The patient lies on the table while an x-ray source moves in a semi-circle around the head of the person. The source is contained inside a tube. The image is created on the basis of differential absorption of the rays. As the beam passes through the brain, it is absorbed at different rates. While bone is good at it, air only takes in a small amount of x-ray, and soft tissue lies on the median. As a result, CT scans are great at creating an outline image of the brain but not apt for defining the structure of it.
  • Functional Activity Testing

a) Functional magnetic resonance imaging is the method wielded when the activity of the brain has to be tested. The tool works by sensing the alterations in:

  • oxygen level in the blood
  • blood flow when neural activity occurs
  • If the mind is active, then there is more flow of blood to it because it consumes more significant amounts of oxygen at this time.

Consequently, fMRI is perfect for creating activation maps that plot out the areas of the brain employed for specific cognitive functions.

b) Positron Emission Tomography is another application that is operated to check brain activity. In this technique, radioactive material is used. As the short-lived substance decays, it produces a positron. The PET scan brain machine recognizes this element. The higher the radioactivity, the more functional is the brain.

  • Electrical Activity Testing

a) Magnetoencephalography is generally utilized in clinics and researches, but they are often helpful in aiding surgeons to localize pathology. Analyses use the technology to find what function each part of the brain performs and neurofeedback. To create an image, the MEG machine employs a gadget called SQUIDs that measure the magnetic field created via electrical movement in the brain.

b) Electroencephalography positions electrode on the scalp of a patient and then use them to create a map of mental electrical activity. EEG essentially traces the electrical signals that are produced by the neurons in any brain. It is one of the frequently applied technology because it is not invasive and is extremely sensitive. The technique can even pick a millisecond of cognitive activity. Furthermore, it is one of the rare few procedures that created a high temporal resolution, i.e., precise measurement with respect to time.

  • Near-infrared spectroscopy puts into service infrared light which falls in the 700 to 900 nm spectrum. The light is shined on the brain from one side and measured as it emerges from the other. The level of oxygen in the blood present in mind defines the attenuation of the light which is a measure of the level of brain activity. NIRS is, therefore, an optical technique of scanning the brain.

The Necessity of Scanning Techniques

Besides the obvious need to spot Cancer, scanning techniques are beneficial for other ailments too. Let’s say a patient has been suffering from painful but intermittent headaches for some time. A physical checkup fails to pinpoint the origin of it. Medication and other treatments do not cure pain.

A brain scan using one of the technologies explained above can detect the underlying issue. The image of the brain would be able to assist a physician in assessing the cause of a headache and thus help in medicating and resolving it.

A doctor, a technician, a physician is only as good as the tools they have. No healthcare practitioner can diagnose a brain condition or disease if the images they have on hand are subpar.

How Does a PET Scan Lung, Heart or on Any Other Body Part Work – Understanding the Basics

How Does a PET Scan Lung, Heart or on Any Other Body Part Work – Understanding the Basics

Positron Emission Tomography or PET is a non-invasive test that creates a nuclear image of any body part such as the lung or heart. To do so, a radioactive tracer also known as radionuclides are injected in the blood. Once the tracer mixes with the blood, it is taken up the muscles and into the organ like the heart. The scan determines if the heart is healthy or not by showing the flow of blood. For example, narrowed arteries or dead cells from a previous heart attack can be diagnosed using a PET scan.

The Basic Workings of A PET Scan

To conduct a PET CT test, the following steps occur:

  1. A tracer is injected to the bloodstream. It is an organic compound found in bodies tagged with a minute amount of radioactive material. Generally, glucose, ammonia or water is used.
  2. Once inside the body, the tracer generates gamma energy rays.
  3. The beams are picked up by a detector that circles the body and then it sends to a computer. The system converts the signals into clear pictures.
  4. The complete image is made by putting together pictures of thin slices of the heart. Each slice is photographed from different directions and angles to produce a holistic and 3-D image.

A healthcare practitioner can determine the functioning of the heart using the picture. If the muscles are strong, the tracer is taken up excellently. On the other hand, if the heart is no longer viable or has dead cells, the tracer is not taken up. On the PET scan, the level of tracer absorption is seen as different colours or brightness gradation.

The Necessity of PET Testing

As of present, PET scans are one of the most precise procedures that can be utilised to detect:

  1. Coronary artery disease
  2. Low blood flow
  3. Injured tissue
  4. Dead tissue

Depending upon what the scan shows, a doctor can recommend a cardiac procedure like:

  1. percutaneous coronary intervention (PCI)
  2. coronary artery bypass surgery
  3. The operations will be able to restore proper blood flow to the heart.

The Procedure of a PET Scan

A pet MRI scan can be done at a hospital or a diagnostic lab. It is conducted by a nuclear medicine technician and a doctor using a PET machine. First electrodes or small metal disks are placed on the legs, arms, and chest of the patient. The electrodes are then attached to a device using wires. These are meant to track and record the heart rate of the patient called electrocardiogram. The ECG also indicates when the scan should be done.

The next step is to create a baseline image of the organ. This is done without the addition of the tracer and takes about half an hour. Once the baseline is scanned, the injection of the tracer through an intravenous line which is taped to the arm of the person takes place. After the tracer is added, the patient lies flat on a table which slides into the scanning device that has an appearance similar to a massive doughnut.

The scan begins when the detectors pick up the signals given off by the tracer. The data is converted into a digital picture using a computer. A single image is, in reality, an accumulation of many photographs taken from all angles and in slices. The entire procedure can take anywhere between one to three hours. It is vital to be completely still during the whole scanning process, or the images come out blurred.

Steps to Take After PET Scanning

Because the scan is a non-invasive process, the person can return to regular activity right after it is finished. It is recommended to drink a lot of fluids for the next day. Water allows for all radioactive material, i.e., the tracer to be flushed from the body. Also, make an appointment with the concerned doctor to do a follow-up on the test results.

The Risks Connected With PET

Commonly, PET scanning is exceptionally safe for any individual. The amount of radiation the body is exposed to is very small. Therefore, the kidneys are able to remove it from the body in at most 24 hours. The test is not recommended if the person is:

  1. Pregnant
  2. Nursing mother

In both cases, the scanning may harm the child.

The Last Word

Any person who wishes to know more about PET scanning before the procedure should consult a doctor. A few questions that can help clarify all doubts are:

  • How is this test better than any other one?
  • What are the steps that should be taken in preparation for the scanning?
  • Will there be a need for additional tests after the scan?
  • When can the results be expected?

A PET scan is a painless procedure, but the anxiety that comes with any health test is always present. It is why to get the scan done at a reputable hospital or diagnostic lab is essential. The technicians and other employees can turn the experience even more comfortable when they are adequately trained. At Anderson Diagnostics, one of the renowned scan centres in Chennai, we take the utmost care of our patients.
