Variable dose application by modulation of x-ray tube current during CT scanning |
摘要 |
An x-ray CT system modulates x-ray tube current as a function of gantry angle to reduce the total patient dose without significantly increasing image noise. A scout scan is performed to acquire attenuation data which enables an optimal current modulation profile to be calculated for each slice in the scan.
