OBTAINING OF IMAGES WITH C-TYPE FRAME WITH ENLARGED ANGULAR STROBING WINDOW Russian patent published in 2017 - IPC A61B6/02 

FIELD: medicine.

SUBSTANCE: C-type frame device for X-ray visualization contains: a C-type frame; a ovable support of the C-type frame; an X-ray source and an X-ray detector. At that, the C-type frame comprises the first end and the second end. The X-ray source is installed at the first end, and the detector is installed at the second end. The C-type frame is mounted on the C-type frame support, so that the X-ray source and the detector are able to move around the object under study along the respective paths of the source and detector, which are two-axis rotation paths based on simultaneous screw motion and roll motion of the C-type frame. The X-ray source comprises the first focal point and a second focal point spaced apart from each other by a distance between the focal points in the bias direction, with bias direction being the same as the source path. The X-ray visualization system contains: a C-type frame device; a mobile means for C-type frame control; and a data processing unit. The data processing unit is configured to control the mobile means for activation of the source and the X-ray detector movement along the respective paths. Also, the data processing unit is configured to control the X-ray source and generate X-rays from the first focal point and the second focal point; and is configured to control the detector and receive the original image data from the detector. The method for tomographic object image data provision comprises the steps of: movement of the X-ray source at the first end of the C-type frame device along the source path and simultaneous movement of the detector at the second end of the C-type frame device along the corresponding detector path; object exposure to the first X-ray radiation from the first focal point towards the detector; or object exposure to the second X-ray radiation from the second focal point towards the detector; detection of the corresponding X-ray radiation from the first and the second X-ray emissions using a detector, and output of the corresponding signals as the original image data. A computer-readable medium storing an element of a computer program adapted to control an X-ray imaging system executed by the data processing unit configured to perform the method steps.

EFFECT: application of this group of inventions allows to obtain improved image acquisition sequences along a two-axis rotation path for subsequent restoration of a 3D image.
