摘要： Portions of the radiation source are obscured so that the radiation only passes through the specific areas of the patient related to the regions-of-interest to the doctor. Scattered radiation received by detector pixels that are obscured by direct-line of sight radiation are used to estimate the scattered radiation in the un-obscured portion, which can be used to increase the accuracy of the image taken through the un-obscured portion.
