SENSITIVITY-OPTIMIZED PATIENT POSITIONING SYSTEM FOR DARK-FIELD X-RAY IMAGING Russian patent published in 2022 - IPC A61B6/08 

FIELD: medicine.

SUBSTANCE: system for dark-field and/or phase-contrast X-ray imaging of a patient by irradiating a patient contains a source node, a detection node, and a patient support node with a surface of contact with a patient. The source node and the detection node are located along the optical axis, and the patient support node is located between them. A contact distance between the source node and the surface of contact with a patient along the optical axis is configurable. The contact distance and the actual sensitivity based on the contact distance are taken into account for imaging. The system is made with the possibility of determination of a target distance between the source node and a patient to be irradiated, at which a field of view will correspond to an area of interest. A method for capture of a dark-field and/or phase-contrast X-ray image, using an X-ray system, contains following stages: a) configuration of the contact distance between the surface of contact with a patient and the source node along the optical axis; b) temporarily fixation of the surface of contact with a patient; c) irradiation of the patient to be irradiated; and d) capture of a dark-field and/or phase-contrast X-ray image. In this case, for the stage a) the following is provided: a1) the patient to be irradiated is placed between the source node and the surface of contact with a patient; a2) the target distance between the node and the patient to be irradiated is determined; and a3) the configured contact distance between the source node and the patient to be irradiated is transmitted into an image generation node. A machine-readable medium, on which a computer program element for control of the system is stored, is made with the possibility, when executed by a processing module, of implementation of stages of the method.

EFFECT: obtaining a patient imaging system.
