ABSTRACT:
Disclosed are methods, systems, and computer-product programs for increasing accuracy in cone-beam computed tomography (CBCT) by obscuring portions of the radiation source so that the radiation only passes through the specific areas of the patient related to the regions-of-interest to the doctor. The obscuring action causes less radiation scattering to occur in the patient's body, thereby reducing a major source of error in the image accuracy caused by scattered radiation. Scattered radiation received by detector pixels that are obscured by direct-line of sight radiation may be used to estimate the scattered radiation in the un-obscured portion, which can be used to further increase the accuracy of the image.
