Tomotherapy is a type of radiation therapy treatment machine. [1] [2] [3] In tomotherapy a thin radiation beam is modulated as it rotates around the patient, while they are moved through the bore of the machine. The name comes from the use of a strip-shaped beam, so that only one “slice” (Greek prefix “tomo-”) of the target is exposed ...

[6] [7] In 2011, Accuray completed its $277 million acquisition of TomoTherapy Inc., creator of advanced radiation therapy solutions for cancer care. [8] In 2012, the company acquired Morphormics for a total $5.7 million. Morphormics was founded by University of North Carolina at Chapel Hill faculty and specialized in developing imaging software.
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.
The Therac-25 is a computer-controlled radiation therapy machine produced by Atomic Energy of Canada Limited (AECL) in 1982 after the Therac-6 and Therac-20 units (the earlier units had been produced in partnership with Compagnie générale de radiologie (CGR) of France).
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.
SPECT machine performing a total body bone scan. The patient lies on a table that slides through the machine, while a pair of gamma cameras rotate around her. To acquire SPECT images, the gamma camera is rotated around the patient. Projections are acquired at defined points during the rotation, typically every 3–6 degrees.
In 1999, according to U.S. Securities and Exchange Commission (SEC) filings, he invested $10 million in TomoTherapy a Madison, Wisconsin, biotechnology start-up. It went public on May 9, 2007, with the stock symbol TOMO. Mr. Cudahy's 10% interest was valued at more than $100 million by September 2007. [citation needed]
