Abstract

The invention discloses a radiotherapy device. The radiotherapy device comprises a radiotherapy part, a sickbed for supporting and moving a patient, a PET monitoring part and a CT monitoring part, wherein the PET monitoring part and the CT monitoring part are arranged in the horizontal moving direction of the sickbed. The radiotherapy device can scan the patient undergoing treatment in real time selectively through the PET monitoring part or the CT monitoring part according to the difference of an illness area, therapeutic schemes are adjusted according to scanning results, radiotherapeutic precision and speed are effectively improved, and the damage to healthy tissue of the patient is reduced as much as possible while the enough radiation dosage is irradiated to a tumor area.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to a radiotherapy equipment with PET and CT monitoring functions. Background technique [0002] Radiotherapy equipment refers to equipment that uses high-energy electromagnetic radiation (X radiation, gamma radiation) or particle radiation (electrons, protons, carbon ions) to destroy diseased tissues, and is widely used in medicine to treat tumors. The radiation center of the radiation therapy equipment produces high radiation doses in a targeted manner, but the problem of the radiation target changing in the body often occurs during the radiation process. For example, the tumor has grown or shrunk in the time between planned radiation and actual radiation. Moreover, during the treatment, the center of the diseased area changes according to the radiation. For this reason, it has been proposed to monitor the position of the radiation target in the body through imaging equipment during t...
