Abstract: A computed tomography imaging system (102) includes an X-ray radiation source (110) configured to emit X-ray radiation that traverses an examination region (108) and an X-ray radiation sensitive detector array (112) configured to detect X-ray radiation traversing the examination region and generate a view of line integrals. The imaging system further includes a subject support table top (118) configured to translate in the examination region for a scan based on at least one scan parameter. The imaging system further includes an operator console (122), which includes a processor (128) and computer readable storage medium (130) with a scan parameter adapter module (132). The processor is configured to execute instructions of the scan parameter adapter module, which causes the processor to determine a contrast agent concentration from the view of line integrals and adjust the at least one scan parameter based on the determined concentration.
