Ferritin is the major protein responsible for storing intracellular iron in prokaryotes and eukaryotes ...
Like a conventional machine used for X-ray external beam radiotherapy (often referred to as a linear accelerator or linac, their main component), it [the tomotherapy machine] generates the radiation beam, but the external appearance of the machine, patient positioning, and treatment delivery differ. Conventional linacs do not work on a slice-by ...
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 ]
The most recent addition to the ITAS system is the ITAS-FTL (far target location), which incorporates a new module called PADS (position attitude determination subsystem), a device that attaches to the top of the ITAS sighting unit and uses differential GPS tracking to relay precise coordinate data to the operator.
Beam's eye view (abbreviated BEV) is an imaging technique used in radiation therapy for quality assurance and planning of external beam radiotherapy (EBRT). These are primarily used to ensure that the relative orientation of the patient and the treatment machine are correct.
The fire-control radar must be directed to the general location of the target due to the radar's narrow beam width. This phase is also called "lighting up". [3] It ends when lock-on is acquired. Acquisition phase The fire-control radar switches to the acquisition phase of operation once the radar is in the general vicinity of the target.
The idealized intersection point of the gantry axis of rotation with that of the collimator and treatment table is known as the mechanical isocenter [2]. In practice, due to the heavy weight and mechanical imperfections of the system, the isocenter is not a single point and its location changes with the rotation of the gantry, collimator or couch.
Pencil beam scanning is the practice of steering a beam of radiation or charged particles across an object. It is often used in proton therapy , to reduce unnecessary radiation exposure to surrounding non-cancerous cells.
