摘要： A treatment planning system is provided which, with irradiation parameters varied over time, performs highly accurate dose distribution calculations based on information about tumor movements included in 4D CT images. The system is characterized by the ability to read CT images furnished with timing information and associate the status of the irradiation target corresponding to an elapsed time from the beginning of irradiation with positions being irradiated at corresponding elapsed time points so as to calculate the dose distribution.

摘要： In a particle therapy treatment planning system for creating treatment plan data, the movement of a target (patient's affected area) is extracted from plural tomography images of the target, and the direction of scanning is determined by projecting the extracted movement on a scanning plane scanned by scanning magnets. Irradiation positions are arranged on straight lines parallel with the scanning direction making it possible to calculate a scanning path for causing scanning to be made mainly along the direction of movement of the target. The treatment planning system can thereby realize dose distribution with improved uniformity.

摘要： Optimal irradiation conditions determined by iterative calculation are based upon an operator-defined irradiating direction, prescription dose, and other conditions. Dose matrixes A and B relating doses to calculation points from a beam delivered to irradiating positions are divided into a dose matrix AM or BM for the calculation points in a target region that are present at distances equal to or less than a distance L from the beam axis of the beam delivered to each spot, and a dose matrix AS or BS for the calculation points that are present at distances greater than L. When the iterative calculation is conducted following completion of the division, dose values and {right arrow over (d)}S(1) and {right arrow over (d)}S(2) that include the dose matrixes AS and BS are regarded as constants, and if updating conditions are satisfied, an objective function is recalculated using the values of the dose matrixes A, B and the spot irradiation dose {right arrow over (x)}.

摘要： There is disclosed a radiation treatment planning system for preparing treatment planning information for carrying out radiation treatment. The apparatus includes an input unit with which an operator inputs a prescription dose and an irradiation angle; an arithmetic unit which prepares the treatment planning information by determining irradiation conditions in such a manner as to bring a dose distribution calculated based on the result of the input from the input unit closer to the prescription dose, and a display unit which displays the treatment planning information. The arithmetic unit sets, per point for radiation irradiation, an index representing the degree of demand for irradiation amount suppression, the degree of demand determined by the radiation irradiation point, and the arithmetic unit further determines the irradiation conditions using the index.
