This is an experimental form of intensity-modulated radiotherapy where higher X-ray dosages are used in fewer fractions (sessions) this is called hypofractionated radiotherapy. Although the dose per fraction is higher than standard radiotherapy, the total dose is lower. [1] The hope is that it will be as effective but cause less toxicity. [1]
Dose fractionation effects are utilised in the treatment of cancer with radiation therapy. When the total dose of radiation is divided into several, smaller doses over a period of several days, there are fewer toxic effects on healthy cells. This maximizes the effect of radiation on cancer and minimizes the negative side effects. A typical ...
Doctor reviewing a radiation treatment plan. In radiotherapy, radiation treatment planning (RTP) is the process in which a team consisting of radiation oncologists, radiation therapist, medical physicists and medical dosimetrists plan the appropriate external beam radiotherapy or internal brachytherapy treatment technique for a patient with cancer.
Radiation therapy (RT) is in itself painless, but has iatrogenic side effect risks. Many low-dose palliative treatments (for example, radiation therapy to bony metastases) cause minimal or no side effects, although short-term pain flare-up can be experienced in the days following treatment due to oedema compressing nerves in the treated area ...
Video shows a disabled senior dog transformed and settling into a new home. Helen, a 15-year-old pup who is blind and deaf, was discovered buried behind a sidewalk slab in an attempt to seek ...
DVH summarizes 3D dose distributions in a graphical 2D format. In modern radiation therapy, 3D dose distributions are typically created in a computerized treatment planning system (TPS) based on a 3D reconstruction of a CT scan. The "volume" referred to in DVH analysis is a target of radiation treatment, a healthy organ nearby a target, or an ...
The SPCA of Texas aims to vaccinate 250 pets free of charge at an upcoming Dallas event, in order to combat deadly diseases that affect our furry friends.
External beam radiation therapy (EBRT) is a form of radiotherapy that utilizes a high-energy collimated beam of ionizing radiation, from a source outside the body, to target and kill cancer cells. The radiotherapy beam is composed of particles, which are focussed in a particular direction of travel using collimators. [ 1 ]
