摘要:
FIELD: medicine.SUBSTANCE: invention relates to medical equipment, namely to visualization systems, used in surgery. Intervention system, which uses medical data of image as a guide for movement of intervention device in one of the versions contains component of superposition, which renews superposition between system of coordinates of image space and system of coordinates of operation space on the basis of information about position of intervention device inside patient, obtained from the data of intermediate image, pointing to the location of intervention device, and position sensor, which is located on intervention device inside patient. In the second version of system implementation there is first component which superposes system of coordinates of image space and system of coordinates of operation space on the basis of space location of at least three standard marks, identified within image data, and space coordinates of at least three standard marks, spatially identified on patient by means of device of location determination, and second component, which uses information about operation device, obtained from intermediate image, formed from image data, obtained after movement of intervention device into patient, for renewal of location measurement, made by device of location determination. Method of superposition between systems of coordinates in intervention system in accordance with the second version is realised during system operation. The third version of system contains means for superposition of coordinate system of image space with coordinate system of operation system on the basis of information about location of standard marks for multitude of standard marks, and means for renewal of superposition on the basis of information about location of intervention device, obtained from intermediate image, information about position of intervention device, obtained from electromagnetic sensor on intervention device, and spatial location of at least three standa
