Computer tomography (CT) has been widely used in medical industry for non-invasive reconstruction of the internal structure of human body. Despite the many benefits reaped from it, patients undergoing CT scans also receive large amount of hazardous x-ray radiations. However, lowering the radiation dose reduces the quality of CT image. The presented work focus on reducing the radiation dose through under-sampled CT reconstruction. This research work investigates the use of interpolation for mitigating the deficiency caused by angularly under-sampled projections. Different interpolation techniques were investigated and implemented using computer simulations.
