20230241414 · 2023-08-03 ·

A boron neutron capture therapy (BNCT) system includes a neutron beam irradiation device, a treatment planning module, and a control module. The neutron beam irradiation device is used to generate a therapeutic neutron beam during irradiation therapy and irradiate same to an irradiated body that has ingested a boron (.sup.10B)-containing drug so as to form an irradiated site. According to medical image data of the irradiated site and a parameter of the therapeutic neutron beam generated by the neutron beam irradiation device, the treatment planning module performs a dosage simulation calculation and generates a treatment plan, the medical image data of the irradiated site comprising tissue-related information and boron (.sup.10B) concentration-related information. The control module retrieves, from the treatment planning module, a treatment plan corresponding to the irradiated body, and controls the neutron beam irradiation device to perform irradiation therapy on the irradiated body according to the treatment plan.

The present invention relates to compositions and methods for imaging and treating various diseases and disorders, including cancers. The composition of the invention can include a plurality of biodegradable micro-beads, each embedding a plurality of nano-beads, further including a polymer, a radionuclide, a radionuclide chelator, a radioligand, a chemotherapeutic agent, and a cell-penetrating peptide. Upon injection into a blood vessel supplying a cancer tumor, the micro-beads lodge into the tumor and degrade, releasing the nano-beads with a therapeutic or diagnostic agent. The compositions and methods of the invention provide a more homogeneous and deeper distribution of radiation or chemotherapeutic agents throughout the target tumor. The micro-beads provide a local, sustained, and controlled delivery nano-beads including therapeutic or diagnostic agents.
