*In clinical practice, the use of Intelli IPV may reduce CT patient dose depending on the clinical task, patient size, anatomical location, and clinical practice. Image noise is defined as the standard deviation of pixel values within an area. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task. Low contrast detectability (LCD) and/or image noise were assessed using reference factory protocols comparing Intelli IPV and FBP. The LCD measured in 0.625 mm slices and tested using the MITA CT IQ Phantom (CCT189, The Phantom Laboratory), using model observer method.
