  • Process, control program, treatment planning system and control system, and dose measuring system for brachytherapy
    Patent number: 7399269
    Abstract: The invention relates to a process for brachytherapy by using a dose measuring system, wherein, in at least one point of an area subjected to radiation treatment, the individual radiation dose contribution from at least one dwell position of at least one radiation source is measured in real time, the thus obtained measured dose value is compared with the corresponding value calculated by a treatment planning system, and the further course of the treatment is adapted on the basis of the degree of agreement between the measured value and the calculated value. Furthermore, the invention relates to a control program, a treatment control system, a treatment planning system and a dose measuring system.
