Abstract:
1. A method for computed tomography (CT) comprising: providing a low energy radiation source oriented towards a subject-receiving area; providing a detector assembly positioned beyond said low-energy radiation source relative to said subject-receiving area; said low energy radiation source and said detector assembly being pivotable in unison about said subject-receiving area; receiving a subject on said subject-receiving area; pivoting in unison both said low-energy radiation source and said detector assembly from a predetermined angular range; directing said low-energy radiation source towards said subject at least at some angular position within said angular range, causing radiation to be transmitted through said subject towards said detector; said radiation transmitted through said subject towards said detector including transmitted photons; detecting and recording position and energy of individual of said transmitted photons; and creating a CT image from said position and energy of said transmitted photons.
