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]
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.
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 ...
Underwater treadmill is used commonly in animal physical therapy. It provides the benefits of land exercises while decreasing the weight placed on the animal's limbs. Underwater treadmill and swimming can be very useful in dogs recovering from surgery, such as anterior cruciate ligament and cranial cruciate ligament repairs and break repairs ...
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 ...
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 ]
A monitor unit (MU) is a measure of machine output from a clinical accelerator for radiation therapy such as a linear accelerator or an orthovoltage unit. Monitor units are measured by monitor chambers, which are ionization chambers that measure the dose delivered by a beam and are built into the treatment head of radiotherapy linear accelerators.
FLASH radiotherapy is an emerging form of radiotherapy which delivers a high dose of radiation to the patient in an ultra-short time frame which produces a tumour killing effect comparable to conventional radiotherapy but with less damage to surrounding healthy tissue.
