Gamma Knife is a highly efficient and sophisticate cancer treatment with optimum precision and zero damage to healthy cells

 


Gamma Knife is a minimally invasive cancer treatment that makes use of computerized radiation therapy planning applications to assist physicians to find and treat small targets inside the brain and head with high accuracy. The application delivers high-powered, high-energy radiation doses directly to the targeted area without harming surrounding tissue. The potential applications for Gamma Knife are virtually endless. However, it is used primarily to treat brain tumors. Gamma Knife treatment is done by using a fractionating method where the surgeon "knife" destroys specific portions of the brain.

External gamma radiation is delivered to the brain via a gamma knife or global magnetic resonance device (GMRD). The device is placed on the head frame and an image is generated by an MRI machine. The gamma knife unit provides high-energy radiation doses directly to specific portions of the brain, targeting its affected tissue. These types of treatments may also be combined with PET (positron emission tomography) scans, which are used to identify brain tumors. Other imaging studies may be performed with the help of gamma radiation and PET/PET-SCI. The advantage of this type of medical physics treatment is that the effects do not wear off after a period of time. In contrast, the results seen from PET-SCI and CET treatment can be seen almost immediately after the last pulse, which means that the patient can experience some discomfort.

Gamma Knife offers a wide range of benefits and advantages over other radiation therapy options. For instance, unlike PET/ PET-SCI or CET (computed tomography) scans, which offer only three dimensions, the gamma knife can offer images of the whole brain, as well as the spinal cord and cerebrospinal fluid. This is particularly useful for treating people with chronic brain damage due to stroke, traumatic brain injury, or multiple sclerosis. Patients who do not respond well to typical treatments may benefit from gamma knife treatment planning software. A software package may also help ensure that you get the best treatment at the lowest cost. Furthermore, Japanese doctors have started treating patients with Elekta’s Leksell Gamma Knife. Recently, in December 2020, Peter MacCallum Cancer Foundation introduced a US$ 8 million gamma knife that allows doctors to kill cancer cells and shrink tumors while avoiding damage to healthy brain tissue.

Increasing Initiatives to Digitalize the Healthcare Sector Is Expected To Boost Demand for Electronic Medical Records

Image
  An electronic medical record (EMR) is essentially a systematized collation of individual patient and family health information in an electronic format. This information is then shared across several health care locations. This will save time, money and provide patients with more comprehensive care. Increasing initiatives to digitalize the healthcare sector is expected to boost demand for EMR. For instance, in November 2019, Germany introduced Digital Supply Act to digitalize healthcare. Under the new legislation, doctors will be able to prescribe digital health apps to patients, which can be reimbursed by the country’s statutory health insurance. There are several advantages to using EMR. The main advantage is that you do not need to wait for the paper records to go through the paper processing before you can use them. Another advantage to electronic medical records is that they allow for greater privacy. Electronic health records allow only the doctor to see these...

Nanocoatings are viable and give security from different ecological components

Image
Nanocoatings have acquired prevalence over the most recent couple of years for different reasons. There are numerous benefits of nanocoatings when look into with customary materials for boats like fiberglass, composite, Kevlar, and so on    Nanocoatings allude to the utilization of coatings to structures to shield them from consumption, mileage and increment their general exhibition. Coatings are by and large applied on steel, solid, rock, tiles, cast iron, stone and wood. Perhaps the most significant and most much of the time utilized types of nanocoatings is the erosion insurance. The principle benefits of utilizing these coatings are consumption insurance, water opposition, hostile to mist, imperviousness to fire and special visualizations. There are different kinds of accessible, which incorporate boundary coatings, contact coatings, epoxy coatings, and so forth The other benefit of is that they don't permit such a consumption because of saltwater or synthetic compo...
