What is Bragg Peak?

Bragg is a point of increased concentration when radiation moves patient tissue. Studies of ionizing radiation show that they slowly lose energy when traveling and energy loss can be graphs according to depth. Initially, the speed may remain consistent, but falls sharply just before the particles rest. This finding has important consequences for radiotherapy, where the aim is to target tumor cells while protecting healthy tissue to limit the side effects for the patient. His work was integrated into protocols developed to guide the use of radiation in cancer therapy. Knowledge of the peak of Bragg makes it possible to calibrate very precisely and target the radiation beam that will hit the tumor in the right place. They use imaging studies and other diagnostic tools to determine the depth and dimensions of the tumor so that the beam can be properly focused.

Radotherapy can also use specific tools to change the shape and structure of the Bragg peak. The beam can be through another medium on the way to pAcient, for example to extend the peak. This can help with full penetration of a large tumor, allowing the beam to cover the entire growth instead of its part. Computer programs help technicians calibrate devices and program the beam to use ionizing radiation as safely and efficiently as possible.

When the peak of Bragg is correctly calibrated, the beam stores a high dose of radiation in the right place. When the tissue passes in front of the tumor, there is some storage of radiation, but should remain much lower than the peak. The radiation stops briefly around the boundaries of abnormal growth and ensures that it does not travel into the surrounding healthy tissue. It may be difficult to calibrate in the axis with low edges for error, such as the intestine, where radiation therapy may come with the risk of perforation and inflammation.

Patients preparing for cancer treatment can receive a number of tests and evaluation before starting treatment. Meou help form treatment adapted to specific cancer to increase the chances of success. During testing, it is important to monitor the instructions to ensure that the technicians get the correct measurements, otherwise the device used to deliver radiation therapy could be incorrectly programmed.
