A medical imaging system (200) includes a masking unit (234), an image registration unit (238), a motion estimator (240) and a motion compensating reconstructor (244). The masking unit constructs a mask for each reconstructed volumetric phase image of a plurality of reconstructed volumetric phase images that masks portions of a corresponding image external to an anatomical model fitted to a segmented at least one anatomical structure, 5 wherein the plurality of reconstructed volumetric phase images include a target phase and a plurality of temporal neighboring phases reconstructed from projection data. The image registration unit registers the masked reconstructed volumetric phase images. The motion estimator estimates motion between the target phase and the plurality of temporal neighboring phases according to the model based on the registered masked reconstructed 10 volumetric phase images. The motion compensating reconstructor reconstructs a motion compensated medical image from the projection data using the estimated motion of the registered masked reconstructed volumetric phase images.

A processing device for a radiation device is configured to carry out the steps of retrieving, from a data storage, volume data of a subject that was generated by imaging an internal structure of the subject, determining a position of an object in the subject based on the retrieved volume data of the subject, obtaining geometry information including a position of a radiation source and a position of a radiation detector, and obtaining a direction of the radiation detector, and determining a condition for imaging with the radiation source, so that the object can be captured through the imaging, based on the volume data, the position of the object, the position of the radiation source, the position of the radiation detector, and the direction of the radiation detector.

An apparatus comprising a radiation source, coincident positron emission detectors configured to detect coincident positron annihilation emissions originating within a coordinate system, and a controller coupled to the radiation source and the coincident positron emission detectors, the controller configured to identify coincident positron annihilation emission paths intersecting one or more volumes in the coordinate system and align the radiation source along an identified coincident positron annihilation emission path.

An X-ray diagnostic apparatus of an embodiment includes processing circuitry. The processing circuitry acquires two medical images, a moving distance of a region of interest between the medical images corresponding to a distance derived from a parallax angle. The processing circuitry causes a display to display a stereoscopic image based on the medical images.

In the X-ray CT system according to an embodiment, a control means displaces and images imaging regions in the subject by controlling a top board driver and an imaging means such that the X-rays are projected onto the subject every time a top board is moved by a predetermined transfer amount. An acquiring means acquires projection data of the respective imaging regions. A reconstruction means, based on the projection data, reconstructs tomographic images for each predetermined size of a reconstruction region. In the scan control mode, the control means outputs the transfer amount corresponding to this mode to the top board driver. In the reconstruction control mode, the control means outputs the size of the reconstruction region corresponding to this mode to the reconstruction means.

The present invention is directed to a perfusion imaging device and method, wherein perfusion data of at least a tissue of interest is obtained from medical imaging and blood pulsation parameters are determined on or near the tissue of interest without physical contact to a patient. Perfusion phase parameters are determined based on the perfusion data and the blood pulsation parameters
