Systems and methods for breast x-ray tomosynthesis that enhance spatial resolution in the direction in which the breast is flattened for examination. In addition to x-ray data acquisition of 2D projection tomosynthesis images ETp1 over a shorter source trajectory similar to known breast tomosynthesis, supplemental 2D images ETp2 are taken over a longer source trajectory and the two sets of projection images are processed into breast slice images ETr that exhibit enhanced spatial resolution, including in the thickness direction of the breast. Additional features include breast CT of an upright patient's flattened breast, multi-mode tomosynthesis, and shielding the patient from moving equipment.

An N-M tomography system comprising: a carrier for the subject of an examination procedure; a plurality of detector heads; a carrier for the detector heads; and a detector positioning arrangement operable to position the detector heads during performance of a scan without interference or collision between adjacent detector heads to establish a variable bore size and configuration for the examination. Additionally, collimated detectors providing variable spatial resolution for SPECT imaging and which can also be used for PET imaging, whereby one set of detectors can be selectably used for either modality, or for both simultaneously.

A tool for radiation therapy simulation or planning is disclosed which aids in avoiding collisions during treatment. Configurations of components including at least a radiation delivery device (30) and a patient (32) are generated. Each configuration defines positions of the components in a common coordinate system. For each configuration, proximities of pairs of components of the configuration are computed using ray tracing between three-dimensional surface models (30m, 32m, 36m, 38m) representing the components of the pair. A collision is identified as any pair of components having a computed proximity that is less than a margin for the pair of components. Each identified collision is displayed on a display (12), e.g. as a rendering. The simulations or planning may be used to verify deliverability of arc, 4Pi, or static therapy, to determine safety margins for collisions, to calculate and display realizable trajectories, and so forth.

A radiation therapy medical apparatus is disclosed. The medical apparatus comprises: a base; a cylindrical gantry, peripherally and rotatably supported by the base; a radiation therapy assembly, comprising an arm and a radiation head, wherein one end of the arm is fixed to a first position on a first side of the gantry and the other end thereof is extended outwardly, and the radiation head is fixed to the other end of the arm; an imaging assembly, mounted to a second side of the gantry opposite to the first side, and configured to be a first balanced weight part for balancing the radiation therapy assembly; and a counterbalance, fixed to the second side of the gantry, and configured to cooperate with the imaging assembly to prevent the gantry from turnover under action of the radiation therapy assembly and configured to dynamically balance with the radiation therapy assembly with respect to a rotation axis of the gantry.

The method corresponds to the aforementioned system. The present invention further relates to an application of the calibration and a computer-readable storage medium capable of implementing the method and the application.

This invention is related to a supervision system that monitors automated movements performed by components of an medical imaging modality, in order to ensure that the moving components behave as expected, while identifying at the same time potential conflicts with (alien) objects or persons in the medical scene. The invention is based on the analysis of differences between measured distance data obtained by a detector that is mounted on the medical imaging modality, and a calculated virtual model of the geometric state of the modality components in the medical scene.
