This utility model discloses an angiography device, comprising: a support arm with a ring structure, wherein a support bearing is fixedly installed in the inner ring region of the support arm, and three sets of X-ray components are installed inside the support bearing. The three sets of X-ray components are evenly arranged in the circumferential direction of the support arm, and each set of X-ray components includes a pair of oppositely arranged X-ray parts and receiving parts; and a first driving unit for driving the inner ring of the support bearing to rotate along its central axis, wherein the rotation angle range of the support arm driven by the first driving unit is not less than 90°. This utility model increases the feasible installation range of the X-ray components by setting the support arm with a ring structure, and the three sets of X-ray components are evenly arranged on the support bearing inside the support arm to achieve three-dimensional imaging of the patient's examination site. At the same time, the setting of the first driving unit can also realize the rotation of the three sets of X-ray components relative to the patient, thereby achieving effective angiography results for patients with different body positions and physical conditions.

A surgery assistance device includes an angiographic image acquisition unit that sets a time interval corresponding to a pulsation cycle of a heart as predetermined intervals and sequentially acquires an angiographic image representing a target blood vessel into which a medical device is inserted at the predetermined intervals, and an image correction unit that sequentially corrects the angiographic image sequentially acquired by the angiographic image acquisition unit, and that generates a corrected angiographic image by correcting the angiographic image to be corrected in such a manner that a position of a specific portion of the medical device included in the angiographic image to be corrected approaches a position of the specific portion of the medical device included in the angiographic image acquired temporally earlier than the angiographic image to be corrected.

The disclosure provides solutions for reducing exposure to radiation in digital subtraction angiography. For this, a method for generating a virtual mask image is proposed. A plurality of images of an object is captured by an angiography apparatus. For at least some of all pixel positions, an extreme pixel value of the pixels of the plurality of images in the respective pixel position is respectively ascertained. The virtual mask image is created from the extreme pixel values at the respective pixel positions.

The invention provides a radiography device and a using method, and relates to the technical field of radiography devices.The radiography device comprises a scanning assembly, and the scanning assembly is suitable for obtaining three-dimensional information of the aortic arch and branch blood vessels on the aortic arch according to preoperative blood vessel image data of a patient; the molding assembly is suitable for customizing the pipe head according to the three-dimensional information; the radiography tube comprises a tube head and a tube body, the tube head is provided with a sealing part, the inner circumferential wall of the tube body is provided with a sealing groove suitable for containing the sealing part, and the sealing part is suitable for expanding when gas or fluid is introduced into the radiography tube. According to the radiography device, the tube head of the radiography tube is customized according to the preoperative blood vessel image data of the patient, so that the radiography tube can better adapt to individual blood vessel differences of different patients, the fitting degree and the adaptability of the tube head and the blood vessel are improved, efficient radiography and treatment are achieved, and meanwhile the radiography effect is improved. The sealing part is contained in the sealing groove and can expand when gas or fluid is introduced into the radiography tube, and the sealing performance between the tube head and the tube body is improved.

The invention relates to the technical field of medical instruments, in particular to an auxiliary decision-making system for bronchial artery embolism and a spring ring operation method, and the system comprises an image recognition module, a case scene analysis module and an interactive display terminal. The image recognition module receives a bronchial artery angiography image transmitted by the angiography equipment, the case scene analysis module receives a responsible blood vessel recognition result and scene feature information, and the interactive display terminal receives and presents the responsible blood vessel recognition result, the scene feature information, an embolism strategy and decision suggestions. Receiving a correction operation of a doctor on the embolism strategy and the decision suggestion, and outputting a personalized embolism scheme according to the correction operation; the output end of the image recognition module is connected with the input end of the case scene analysis module, and the output end of the case scene analysis module is connected with the input end of the interactive display terminal. Through image processing, strategy generation, correction supporting and spring ring matching operation, disease adaptation, error reduction, safety protection and treatment standardization promotion are realized.
