Tilted detector array for medical imaging systems including computed tomography

摘要

A medical imaging system can include a frame that has a bore that has a central longitudinal axis that intersects a target area for imaging, and a radiation source to emit radiation in radial directions towards the target area to form a fan or cone of emitted radiation that irradiates a cross-section of the target area with respect to the longitudinal axis. The system can include one or more detector arrays including a plurality of detector segments that extend along a detector axis that extends in a direction that is effectively parallel to the longitudinal axis, such that radiation emitted from the radiation source passes through the target area and is incident on one or more of the detector segments. The detector segments can each include a detecting surface that is tilted such that the detecting surface has a tilt (e.g., a non-zero slope) with respect to the detector axis.

1. A medical imaging system, comprising:
a frame that has a bore that has a central longitudinal axis that intersects a target area for imaging; a radiation source to emit a fan or cone of emitted radiation in radial directions towards the target area so as to irradiate a cross-section of the target area with respect to the central longitudinal axis; and a detector array including a plurality of detector segments that extend along a detector axis that extends in a direction that is substantially parallel to the central longitudinal axis, the plurality of detector segments being arranged such that the fan or cone of radiation emitted from the radiation source passes through the target area and is incident on one or more of the plurality of detector segments, wherein each detector segment of the detector array includes a detecting surface that is tilted such that the detecting surface has a tilt with respect to the detector axis.
