Abstract
Disclosed is a neutron capture therapy apparatus. The neutron capture therapy apparatus is used for irradiating a neutron beam with a preset neutron dose to an object to be irradiated. The neutron beam enters the object and undergoes a nuclear reaction with boron in the object. The neutron capture therapy apparatus includes a correction system for correcting the preset neutron dose.
Claims8
A neutron capture therapy apparatus, configured to irradiate a neutron beam with a preset neutron dosage to an object to be irradiated, the neutron beam entering the object to be irradiated and undergoing a nuclear reaction with boron in the object to be irradiated, and the neutron capture therapy apparatus comprising:
- a correction system configured to correct the preset neutron dosage;
- and
- a detection system, comprising a neutron dosage detection device configured to detect a dosage of the neutron beam in real time and a boron concentration detection device configured to detect a boron concentration in the object to be irradiated, wherein correction coefficients used by the correction system comprise a boron self-shielding effect correction coefficient Ks calculated by using a formula (3-6);
