  • TREATMENT PLANNING SYSTEM, METHOD, AND PROGRAM
    Publication number: 20240285972
    Abstract: A treatment planning system is configured to create a treatment planning for radiotherapy and includes a processing device and a memory. The memory stores a plurality of calculation models, and the processing device uses at least two of the plurality of calculation models to calculate calculation values of biological effect indices representing an effect of radiotherapy with respect to a condition for radiotherapy, and searches for the condition so that at least two of the calculation values to be calculated approach a predetermined target value.

  • Moving body tracking apparatus, radiation therapy system including the same, program, and moving body tracking method
    Patent number: 11282244
    Abstract: Provided are a moving body tracking apparatus that contributes to shortening treatment time and a radiation therapy system including the moving body tracking apparatus, a program, and a moving body tracking method. The moving body tracking apparatus includes a fluoroscopic apparatus that acquires fluoroscopic images including the target 2 from at least two directions, and the moving body tracking control apparatus 30A that obtains a position of the target 2 from the fluoroscopic images acquired by the fluoroscopic apparatus. The moving body tracking control apparatus 30A creates a simulated fluoroscopic image from the CT image including the target 2, creates a two-dimensional region including the target 2 from the simulated fluoroscopic image as a template, matches each of at least two fluoroscopic images with the template, and obtains a three-dimensional position of the target 2 from a plurality of matching results.
