Integrated automatic exposure control for portal imaging in radiotherapy |
摘要 |
Method and system aspects for integrated automatic exposure control for portal imaging in radiotherapy are described. In an exemplary method aspect, the method includes controlling scanning and blanking of a target of a camera pick-up tube to capture an initial image, and analyzing the initial image to establish an initial image intensity. The method further includes utilizing the initial image intensity to determine a time for scanning a next image, and combining a scan of the next image with the initial image to produce a portal image with a maximized signal to noise ratio.
