	(SPN) Standard Product Nomenclature			A0847583	AT20134694	A medical charged-particle radiation therapy system is a device that produces by acceleration high energy charged particles (e.g., electrons and protons) intended for use in radiation therapy. This generic type of device may include signal analysis and display equipment, patient and equipment supports, treatment planning computer programs, component parts, and accessories.
	UMD			A10986257	AT102972014	Radiotherapy systems designed to produce electron beams of varying energies in addition to high-energy photons using a linear accelerator (linac) as a generator. A linear accelerator consists of a modulator, an electron gun, a radio-frequency power source (either a magnetron or a klystron), and an accelerator guide. The range of the energy levels provided by linacs is very wide, from 4- to 6-megavolt (MV) photons for low-energy units to 25 MV photons and up to 22 mega-electron-volt electrons in high-energy units. These systems also include control units, filters, and collimators. Low-energy linear accelerator systems are mostly used to treat tumors of the head, neck, and breast; high-energy systems are used to treat deep-seated neoplasms and tumors of the pelvis and thorax.
