The successor to the popular TomoTherapy system, Radixact provides an image-guided, adaptive, intensity modulated radiation treatment (IMRT) option that is designed to target tumors anywhere in the body while significantly reducing common side effects.
Which is better IGRT vs IMRT?
IGRT uses imaging with the therapy to increase the efficiency by improving the precision and accuracy of the treatment procedure. The IMRT therapy uses high-edged software and sophisticated hardware to vary the intensity and shape of radiation used for different parts of the treatment area.
What is IGRT TomoTherapy?
TomoTherapy is a Revolutionary Way to Treat Cancer It combines precise 3-D imaging from computerized tomography (CT scanning) with highly targeted radiation beams to deliver radiation with extreme precision to treat the cancer while minimizing damage to surrounding tissues.
Is TomoTherapy better than radiotherapy?
However, the study, “Evaluation of Arc-based Intensity Modulated Radiotherapy for Head and Neck Cancer,” published in 2009 in the International Journal of Radiation Biology Physics[1], found tomotherapy plans better at sparing surrounding healthy tissue, and VMAT’s treatment delivery time faster.
When was TomoTherapy invented?
History. The tomotherapy technique was developed in the early 1990s at the University of Wisconsin–Madison by Professor Thomas Rockwell Mackie and Paul Reckwerdt.
What is the difference between TomoTherapy and linear accelerator?
IGRT solutions are available for both tomotherapy and conventional linear accelerators. Tomotherapy provides megavoltage fan-beam CT scanning while conventional lin- ear accelerators can provide kilovoltage cone-beam CT.
How much does a TomoTherapy machine cost?
Cost: TomoTherapy’s Hi-Art radiation cancer treatment machines cost about $3 million and are the company’s primary product.
What is the success rate of TomoTherapy?
During the follow-up period, 29 patients (78.4%) from the conventional RT group and 28 patients (93.3%) from the helical tomotherapy group were still alive. The 1- and 2-year overall survival rates were 93.9% and 87.1% for the conventional RT group, 96.6% and 96.6% for the helical tomotherapy group, respectively.
When is TomoTherapy used?
What Is TomoTherapy Used For? TomoTherapy’s accuracy, modulation and 360-degree delivery make it ideal for tumors that are hard to reach or next to vital organs. It’s also used to treat multiple tumors at once and re-treat areas, with fewer side effects.
Is proton therapy better than conventional IMRT?
Protons vs Photons In the low-dose range, however, IMRT had worse performance characteristics than proton therapy due to the fact that IMRT spreads out the dose over several beams. The rectal V30 was reduced with protons by between 16% and 53% compared to IMRT.
What are the side effects of IMRT?
hair loss in the treatment area
How long does it take to treat an IMRT patient?
Usually, an IMRT treatment takes about 10 to 30 minutes. You may be in the treatment room for up to an hour, but every cancer is different. It’s a good idea to ask your doctor what to expect in your particular case. While each procedure will be short, you’ll need more than one.
Does IMRT cure cancer?
IMRT may also be beneficial for treating pediatric malignancies. Radiation therapy, including IMRT, stops cancer cells from dividing and growing, thus slowing or stopping tumor growth. In many cases, radiation therapy is capable of killing all of the cancer cells, thus shrinking or eliminating tumors.
