ABSTRACT:
The present invention discloses a method and system for generating Radon derivative data in a cone beam computerized tomography implementation. Radon derivative data is computed by using a plurality of processors that partition the Radon space among the processors in a manner wherein the totality of the support of the Radon space handled by each processor is approximately equal. More specifically, each processor handles a number of vertical planes in the Radon space which are equally spaced within 180.degree. in the .phi..sub.k orientation. This procedure enables the plurality of processor to equalize the workload in computing the Radon derivative data and to perform the computations in a timely and efficient manner.
