Abstract: A system is provided for fasting switching a filter of an imaging system during a scan. In one embodiment, a system comprises a computation device with instructions stored in a non-transient memory to emit an X-ray beam via an X-ray source; move an imaging subject via a motorized table at a nonzero speed; while moving the imaging subject, acquire a dataset of the imaging subject by detecting attenuated X-rays transmitted through the imaging subject via an X-ray detector, wherein a first filter is positioned within the X-ray beam, between the X-ray source and the imaging subject; and while acquiring the dataset, responsive to a change in an anatomy of the imaging subject to be imaged, operate a filter driving system to switch from the first filter to a second filter, wherein during filter switching, the X-ray source does not emit X-rays.

Abstract: An aperture comprises blocking members and for blocking X-rays. The blocking member has: an edge formed on an arc A1 lying on a circumference CF2 of a circle with radius r2 around a focal spot f in an XY-plane; an edge connected to one endpoint of the edge, the edge being formed to lie on the side of the X-ray detector with respect to an arc A11 contiguous to the arc A1; and an edge connected to the other endpoint of the edge, the edge being formed to lie on the side of the X-ray detector with respect to an arc A12 contiguous to the arc A1. The blocking member has: an edge formed on an arc A2 lying on the circumference CF2 of the circle with radius r2 around the focal spot f in the XY-plane; an edge connected to one endpoint of the edge, the edge being formed to lie on the side of the X-ray detector with respect to an arc A21 contiguous to the arc A2; and an edge connected to the other endpoint 23b of the edge, the edge being formed to lie on the side of the X-ray detector with respect to an arc A22 contiguous to the arc A2.

Abstract: A tilting head support for use in medical imaging is described. The tilting head support allows a patient to receive the equivalent of a tilted gantry exam study even when using a scanner gantry that does not tilt. In certain embodiments, the tilted head support assembly has metallic or sharp edge components, if present, positioned outside the imaging area when in use. In addition, in certain embodiments, the tilted head support assembly allows for user selection of a tilt angle from among a continuous range of available angles.

Abstract: Method and apparatus are provided for aligning a cradle supported by a table in an imaging system with a gantry scan plane in a bore of the gantry. More particularly, various embodiments provide a laser alignment structure having at least two alignment apertures arranged along an axis of the bore, and an adjustment device configured to adjust a position of the laser so that the laser beam is aligned with the alignment apertures. Highly accurate alignment of the cradle to the gantry scan plane is achieved by utilizing this apparatus in tandem with an imaging-based alignment analysis method.

Abstract: Methods and systems are provided for fasting switching a filter of an imaging system during scan. In one embodiment, a method comprises determining a first contrast enhancement of an injected contrast agent; responsive to the first contrast enhancement being higher than a first threshold, acquiring a first dataset by transmitting a radiation beam to an imaging subject via a first filter; switching to a different, second filter; acquiring a second dataset by transmitting the radiation beam to the imaging subject via the second filter, wherein an average contrast enhancement of the injected contrast agent during the acquisition of the first dataset is substantially the same as an average contrast enhancement of the injected contrast agent in the imaging subject during the acquisition of the second dataset.

Abstract: A method is provided. The method includes partially supporting a subject to be imaged on a board extending from a mobile patient transport into a gantry bore of a stationary computed tomography (CT) imaging system while partially supporting both the subject and the board with a cradle extending from a table. The method also includes acquiring a single imaging volume, during an imaging scan with the stationary CT imaging system, without moving the subject.
