A survey of patient dose and image quality factors for CT scanners in Victoria.
Image quality and dose parameters have been measured on most makes and models of CT scanners in Victoria. Image quality was assessed using a dose efficiency and imaging performance parameter (Q-value). Factors relating to patient dose were measured. Patient doses using CTDIw in mGy were determined for average size patients for the abdomen procedure. Guidance levels have been recommended for CT procedures in Victoria.
