请问有人了解TOMO刀吗？？听说是最先进的放射疗法

At this time, the HiArt system manufactured by TomoTherapy, Inc. is the primary tomotherapy device in use although there are still a number of Corvus systems being used. Other radiation therapy equipment vendors have recently responded to the challenge of short treatment times coupled with a full 360 degree treatment arc by developing methods of delivering IMRT using arcs. The major difference is that these methods are implemented on standard medical linear accelerators, thereby providing for complete volumetric irradiation.

TomoTherapy "beam on" times are comparable to normal radiation therapy treatment times (about 3–5 minutes beam on time for a common prostate treatment) but do add an additional 2–3 minutes for a daily CT. The daily CT is used to precisely place the radiation beam and allows the operator to modify the treatment should the patients anatomy change due to weight loss or tumor shrinkage (adaptive radiotherapy). Lung cancer, head and neck tumors, breast cancer, prostate cancer, stereotactic radiosurgery and stereotactic body radiotherapy are some examples of treatments commonly performed using TomoTherapy. While the first clinical use of TomoTherapy was in 2002, at the University of Wisconsin, under the leadership of Dr. Minesh Mehta, M.D., there are now more than 300 sites across Canada, the United States, Europe and Asia
