Patent ID: 7315757

Claim:
Method of radiation treatment of the malignant neoplasm with the purpose of damaging its cells utilizing X-ray radiation beams, comprising the steps of: introducing gadolinium-containing substance into patient body; emitting X-ray radiation with energy corresponding to K-edge of gadolinium atoms absorption; using a concentration element, concentrating the X-ray radiation in a concentration zone within the part of patient body containing the malignant neoplasm; transporting secondary radiation arising in said zone to at least one detector having maximum sensitivity in a spectral region corresponding to K α -radiation of gadolinium atoms, for providing selective secondary radiation detection; scanning the part of patient body containing the malignant neoplasm by relative displacement of the concentration zone and the patient body; performing registration of the secondary radiation excited in the concentration zone using said at least one detector; performing registration of parameters, which characterize spatial position of the concentration zone and a field of vision of said at least one detector having a signal detected at the output; identifying each of regions common for the concentration zone and the field of vision of said at least one detector having a signal detected at the output, as containing cells of the malignant neoplasm; determining position of the malignant neoplasm based on the identified regions; and executing an irradiation program developed as a set of X-ray radiation doses that should be supplied to various points of the malignant neoplasm, by placing the concentration zone in positions corresponding to the determined position of the malignant neoplasm, using the concentration element utilized for detecting position of the malignant neoplasm, the irradiation program being executed by controlling duration of irradiation at an increased intensity level of X-ray radiation compared to X-ray radiation intensity provided for detecting position of the malignant neoplasm.
