Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically to a BNCT mouse irradiation device that does not require anesthesia. Background Technology

[0002] Boron neutron capture therapy (BNCT) is a novel radiotherapy technique that utilizes the interaction between neutrons and boron to precisely target cancer cells. BNCT-related biological experiments are crucial for evaluating treatment efficacy, optimizing treatment regimens, and exploring its effects on normal tissues. Biological experiments typically require the establishment of animal models. Mice are widely used as research subjects. BNCT-related biological experiments generally require irradiating specific sites on mice after anesthesia; however, anesthetic drugs can suppress the immune system, respiratory function, and circulatory function of mice, potentially affecting the evaluation of BNCT's therapeutic effect. In practice, because biological experiments require statistical analysis of results from multiple samples and may irradiate different sites on mice, there is a need for a mouse irradiation device that does not require anesthesia for BNCT.
