Patent ID: 7838852

Claim:
A medical radiation apparatus for irradiating a tissue of a patient during a course of a therapy, comprising: a medical imaging diagnosis device that generates a recording of the tissue to be irradiated; a beam source that generates a radiation; a deflection apparatus that directs the radiation to the tissue; a data processing device that activates the beam source and the deflection apparatus according to a radiation schedule of the therapy based on the recording, wherein the data processing device is configured to determine a plurality of original characteristics of radiation acting on the tissue, the data processing device being further configured to determine at least one modified characteristic of subsequent radiation acting on the tissue, the modified characteristics being determined by the data processing device based on a plurality of different irradiation scenarios of irradiation operations at different times, wherein the plurality of different irradiation scenarios comprises a first irradiation scenario based on the generated recording of the tissue to be irradiated, and further includes a simulated second irradiation scenario based on a changed physical condition of the tissue subsequent to applying to the tissue a first irradiation constructed in accordance with said first irradiation scenario, the data processing device configured to generate an image consisting of boundary surfaces corresponding to a distal boundary and to a proximate boundary relative to a beam of radiation from the beam source, the image arranged to visually contrast a radiation spatial distribution in the changed tissue with respect to a radiation spatial distribution resulting from the first irradiation applied to the tissue; and a display device coupled to the data processing device to simultaneously display the radiation spatial distribution in the changed tissue with respect to the radiation spatial distribution resulting from the first irradiation, wherein a displacement of the proximate boundary in a direction of the radiation beam is defined in a displayed image, the boundary displacement allows an operator to adapt the radiation therapy by way of a respective adjustment to at least one operating parameter to account for the changed physical condition of the tissue as the tissue undergoes the radiation therapy.
