Abstract: A system and method are provided for creating an image including quantified flow within vessels of a subject. The method includes providing a single-sweep, three-dimensional (3D) image volume acquired from a subject during a single pass of a computed tomography (CT) imaging system as the subject receives a dose of a contrast agent and determining a phase shift corresponding to pulsatile contrast in vessels within the single-sweep, 3D image volume. The method further includes quantifying a flow through the vessels within the single-sweep, 3D image volume using the phase shift and generating a report including indicating flow through the vessels within the 3D image volume.

Abstract: A system and method are provided for creating both angiographic images of a subject and dynamic images of the subject from imaging data acquired during an imaging acquisition. The method includes operating an imaging system to perform an imaging acquisition by delivering interspersed doses of high doses of the ionizing radiation and low doses of the ionizing radiation, wherein more low doses of the ionizing radiation are delivered than high doses of ionizing radiation during the imaging acquisition to thereby acquire the imaging data with a high frame rate of low dose data and a low frame rate of high dose data. The method also includes generating at least volumetric angiographic images of the subject and dynamic images of the subject from the imaging data.

Abstract: A system and method is provided for imaging a contrast agent. The system includes a power injector that delivers a contrast agent as a series of boluses using a known period, flow rate, or duration and with a rate of at least one or more separate boluses per cardiac cycle. An x-ray imaging system acquires a reference dataset of the subject before the contrast agent is delivered and acquires an imaging dataset as the series of boluses are delivered to the subject, wherein multiple images are acquired of the subject per bolus. A computer system receives the reference dataset and the imaging dataset from the x-ray imaging system and reconstructs the reference dataset and the imaging dataset using a reconstruction process that removes the subject from the images to generate time-resolved volumetric images of the contrast agent moving within a volume of the subject without the subject.

Abstract: A system and method are provided for medical imaging that includes acquiring, during a common imaging acquisition process, rotational, x-ray volume image data and x-ray tomosynthesis image data from a subject. The method includes reconstructing a time-resolved three-dimensional (3D) image volume from the rotational, x-ray volume image data and producing a four-dimensional (4D) image series of the subject with resolved overlapping features by selectively combining the time-resolved 3D image volume and the x-ray tomosynthesis imaging data.

Abstract: A brace that includes at least one chin rest for stabilizing a patient's jaw in a fixed relative position. More specifically, the at least one chin rest is itself supported in its fixed position using additional mechanisms such as a chest plate or one or more arms that can be attached to a dental or oral surgical chair. The brace is used to stabilize a patient's jaw when the patient's jaw is supported by the at least one chin rest.

Abstract: A system and method are provided for generating images that track a position and shape of a medical device within a subject. The method includes acquiring image data from a subject along at least two disparate view angles, each view angle including a deformable medical device arranged in the subject. The method also includes receiving images reconstructed from the image data and exploring a search space to compare the images with a dynamic three-dimensional (3D) model at least using a deformation parameter to determine a position and shape of the deformable medical device within the subject. The method further includes displaying an image of the subject and deformable medical device arranged within the subject based on the position and shape of the deformable medical device within the subject.

Abstract: Measurement of the rotating angle of two objects rotating in relation to each other is achieved with a transmitter assigned to one of the objects. The transmitter emits light that is either polarized or becomes polarized by means of a polarization filter, and with a polarization-sensitive polarizer such that the transmitter and the polarizer rotate relative to each other as dependent on the rotating angle. A receiver measures the luminosity of light passing through the polarizer in order to create a signal that is dependent on the rotating angle, and where the receiver has at least two receiver elements which detect light of differing polarization.
