Patent ID: 7902530

Claim:
A dynamic radiation therapy field shaping system with multiple radiation sources arranged in a circle and combined with a computerized tomotherapy device for image guided all field simultaneous conformal radiation therapy by means of 2, 3, 4 or more radiation sources and beam shaping blocks made in conformity with the shape of the tumor and said conformal blocks are made with the aid of a plurality of block making assembly, one for each of the radiation sources and said radiating beam is shaped in conformity with the shape of the tumor as it is seen per each beam's eye view to treat a tumor through 2, 3, 4 or more fields simultaneously and said conformal dynamic filed shaping is with the aid of simulating conformal light beam seen as coming from each of the radiation sources and passing through Styrofoam that is cut in conformity with the shape of the tumor in a patient who is treated and placed underneath the radiation source to aid to make the said dynamic conformal block and comprising: a. multiple radiation sources configured in a circle b. a computerized tomography device for imaging c. field shaping block configured with Styrofoam cuts that conform with the anatomy of the target tumor, d. field shaping block making assembly comprising an upper and lower reservoir for holding fluid material used for field shaping block, e. said field shaping blocks made as dynamic instantaneous blocks by dispensing the block forming material from the reservoirs located on a platform below each of the radiation sources.
