METHOD AND APPARATUS FOR EVALUATING A CHANGE IN RADIATION DISTRIBUTION WITHIN A TARGET TISSUE

摘要

An apparatus for evaluating a change in radiation distribution within a target tissue of a patient, the apparatus constituted of: a memory having stored thereon parameters of radiation to be output by an irradiation source, the radiation parameters determined responsive to a reference image of the patient target tissue; a processor in communication with the memory; and an output module in communication with the processor, wherein the processor is arranged to: receive a present image of the patient target tissue; determine the expected distribution of radiation within the patient target tissue for an irradiation incidence according to the stored radiation parameters; determine the difference between the determined distribution and a predetermined distribution parameter; and control the output module to output a signal responsive to the determined difference.

1. An apparatus for evaluating a change in expected radiation distribution within a target tissue of a patient, the apparatus comprising:
a memory having stored thereon parameters of radiation to be output by an irradiation source, the radiation parameters determined responsive to a reference image of the patient target tissue; a processor in communication with said memory; and an output module in communication with said processor, wherein said processor is arranged to:
receive a present image of the patient target tissue;responsive to said received present image, determine the expected distribution of radiation within the patient target tissue for an irradiation incidence according to the stored radiation parameters;determine the difference between said determined distribution and a predetermined distribution parameter; andcontrol said output module to output a signal responsive to said determined difference.
