This thesis first aims to understand how a part of the computed tomography (CT) algorithm called “forward projector” (FP) works and how it can be accelerated at a hardware level. Two methods of FP are defined and studied: pixel-driven and ray-driven. Both methods fundamentally use the property of line integral and Bresenham’s algorithm. As the result of the study of the two FP methods, the ray-driven algorithm implemented in C++ performed 35% faster than the pixe-driven algorithm implemented in Python.This thesis implements the ray-driven forward projector algorithm using field-programmable gate array (FPGA), making use of hardware-acceleration techniques. The result shows …
