摘要：<p>Cone-beam reconstruction is performed within a practically acceptable time on a computer having one or more microprocessors. The calculations involved in the reconstruction are divided into calculations to be performed on the MMX, ALU and SSE units of each of the microprocessors. For pure floating-point data, it is preferred to use the MMX unit to adjust the data address and map data and to use the SSE unit to perform the backprojection. The data are partitioned by z-line so that the data to be processed in each stage of the backprojection fit within the L1 cache.</p>
