The Maximar-100 was a widely-adopted superficial radiation therapy unit. Precise naming and definitions of energy ranges may vary, and X-rays at the lower end of this range may also be known as Grenz rays. [2] They are useful in radiation therapy for the treatment of various benign or malignant skin problems, including skin cancer and severe ...
Maximar 100 X-Ray Unit Superficial Therapy The Maximar-100's x-ray source is the GE SRT-1, [ 1 ] an x-ray tube specifically designed for use in the Maximar-100. This is a fixed-anode, reflection-type x-ray tube, whose name is composed of three parts: "SR" meaning self-rectified, "T" meaning therapeutic, and "1" indicating a 1-mm diameter ...
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 ...
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 ]
It has also been used with Stereotactic Body Radiation Therapy to assist with the initial set-up and detect intrafraction patient motion throughout treatment. [3] For stereotactic surgery , SGRT allows a frameless system to be used to monitor the surface of the patient within an open-face immobilization mask.

Radiosurgery is surgery using radiation, [1] that is, the destruction of precisely selected areas of tissue using ionizing radiation rather than excision with a blade. Like other forms of radiation therapy (also called radiotherapy), it is usually used to treat cancer.
Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
