Abstract
A computed tomography (CT) apparatus including: an X-ray source configured to direct X-rays toward a detector assembly; a dynamic beam collimator fixed in space and configured to dynamically limit an X-ray beam directed toward an object of interest, the dynamic beam collimator including a plurality of leaflets to block a cone beam of X-rays impinging upon the dynamic beam collimator, wherein a subset of the plurality of leaflets opens and closes to block or allow a portion of the cone beam of X-rays to reduce or increase a solid angle of the cone beam, wherein the cone beam of X-rays with the reduced solid angle is directed toward a predetermined portion of the object of interest; and the detector assembly configured to detect the directed cone beam of X-rays on a side opposite to the X-ray source.
