  • Virtual compensator
    Patent number: 5724403
    Abstract: In a radiation emitting device, particularly in a radiation treatment device (2), the actual radiation delivered to an object (13) via a radiation beam (1) is adjusted to match the field to be irradiated on object (13). Jaws (250, 252, 254, 256) are arranged between a radiation source and an object (13) to provide an opening (110). The field is divided up into sections, and wedge corrections and/or monotonic functions are calculated for each of the sections. The wedge corrections and/or monotonic functions are used to deliver radiation to each of the sections in the field. Jaws (250, 252, 254, 256) and the radiation dose are controlled during the treatment of each of the sections.

  • Optimization of an intensity modulated field
    Patent number: 5663999
    Abstract: In a radiation emitting device, particularly in a radiation treatment device (2), the radiation treatment for an object (13) via a radiation beam (1) is determined. The field on the object to be irradiated is inputted and then divided up into sections (220-230). Plates or a collimator are arranged between a radiation source and an object (13) to provide an opening over one of sections (220). A radiation beam (1) is generated and used to treat one of sections (220) with radiation. This is repeated until each of sections (220-230) are treated with radiation.
