Often in clinical CT imaging situations, a clinician only requires a small volume of interest (VOI) within aCT slice to be imaged. Unfortunately, due to some fundamental constraints in CT image reconstruction, the entire slice must be irradiated even when a small VOI is all that is clinically required. This produces excess dose for the patient, excess scatter which degrades image quality and increases clinician dose, and may effect patient care because clinicians may limit their use of CT in… CONTINUE READING
