1. Low contrast detectability (LCD), image noise, spatial resolution and artifacts were assessed using reference factory protocols comparing ASiR-V and FBP. The LCD measured in 0.625 mm slices and tested for both head and body modes using the MITA CT IQ Phantom (CCT183, The Phantom Laboratory), using model observer method.

2. In clinical practice, the use of ASiR–V may reduce CT patient dose depending on the clinical task, patient size, anatomical location and clinical practice. 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. 

3. ASiR-V is an option on some configurations.

4. Actual results may vary depending on the circumstances, including but not limited to, exam type, clinical practice, and image reconstruction technique. This information was based on a simulation using the GE Healthcare Optima^TM CT660 device and is presented for illustrative purposes only.

5. As demonstrated in cardiac phantom testing.

6. DoseWatch is optional.

7. Optional.

8. Smart MAR is an option on some configurations.
