By 1960, Grubbe had instructed over 7000 other doctors in the medical use of x-rays. [1] In the course of his lifetime, he underwent more than 90 operations for multiple cancers caused by his intense, ongoing exposure to radiation, [ 5 ] a disease from which he died.
As a form of exercise, dance therapy can be useful for both physical and emotional aspects of quality of life." [120] A Cochrane review found too few studies to draw any conclusions about what effects dance therapy has on psychological or physical outcomes in cancer patients. [121]

Historically conventional external beam radiation therapy (2DXRT) was delivered via two-dimensional beams using kilovoltage therapy X-ray units, medical linear accelerators that generate high-energy X-rays, or with machines that were similar to a linear accelerator in appearance, but used a sealed radioactive source like the one shown above.
Superficial radiation therapy machines produce low energy x-rays in the same energy range as diagnostic x-ray machines, 20–150 keV, to treat skin conditions. [3] Orthovoltage X-ray machines produce higher energy x-rays in the range 200–500 keV. Radiation from orthovoltage x-ray machines has been called "deep" due to its greater penetrating ...
A linear accelerator (linac) produces x-rays from the impact of accelerated electrons striking a high z target, usually tungsten. The process is also referred to as "x-ray therapy" or "photon therapy." The emission head, or "gantry", is mechanically rotated around the patient in a full or partial circle. The table where the patient is lying ...
Megavolt X-ray (or photon) therapy, which delivered a beam of 25 MeV X-ray photons. The X-ray photons are produced by colliding a high current, narrow beam of electrons with a tungsten target. The X-rays are then passed through a flattening filter, and then measured using an X-ray ion chamber. The flattening filter resembles an inverted ice ...
Blood irradiation therapy is an alternative medical procedure in which the blood is exposed to low-level light (often laser light) for therapeutic reasons. [1] The practice was originally developed in the United States, [ 1 ] but most recent research on it has been conducted in Germany (by UV lamps ) and in Russia (in all variants).
