Embodiment

[0038] Example: Combine image 3 and Figure 4 The image recognition method for ensuring the safety of magnetic resonance scanning provided by the present invention is specifically described as follows, which has the following steps:

[0039] A. Obtain the contour edge of the scanning magnetic resonance bed through the optical camera in advance, and draw the scanning safe area;

[0040] B. When the target is in place, use the infrared camera to obtain the infrared image of the detected object;

[0041] C. Merge the infrared image of the detection object obtained by the infrared camera with the outline image of the bed obtained by the optical camera, identify the edge pixels of the detection object and the edge pixels of the bed body through the edge detection algorithm, and pass the edge pixels of the detection object Compared with the pixel points on the edge of the bed, it is determined whether the detected object is within the scanning safe area;

[0042] D. According to...

Abstract

The invention discloses an image recognition method for ensuring magnetic resonance scanning safety. The image recognition method for ensuring magnetic resonance scanning safety is characterized by comprising the following steps that A, a contour edge image of a bed for scanning magnetic resonance is acquired through an optical camera in advance, and a scanning safety area range is drawn; B, whena target is in place, an infrared camera is used for obtaining an infrared image of the detected object; C, the infrared image which is acquired by the infrared camera of the detected object is fusedwith the contour image which is acquired by the optical camera of the bed, edge pixel points of the detected object and edge pixel points of a bed body are identified by an edge detection algorithm, and whether the detected object is in the safety area range or not is determined by comparing the edge pixel points of the detected object with the edge pixel points of the bed body; and D, the bed iscontrolled to move or stop according to the judgment result of the step C. The method can effectively avoid the risk of collision between limbs of a patient and a magnet shell in the magnetic resonance scanning process and better ensure the inspection safety. The invention further discloses an image recognition system based on the method.

Description

technical field [0001] The invention relates to an image recognition method and system for ensuring the safety of magnetic resonance scanning. Background technique [0002] In the process of MRI scanning, it is generally divided into four steps: (1) The doctor asks the patient to position himself on the scanning bed according to the scanning requirements; (2) The doctor selects the coil according to the part to be scanned, and performs laser positioning by moving the bed, so that The scanning center position of the patient coincides with the laser positioning; (3) The doctor loads the scanning sequence and scans; (4) Ends the scanning. [0003] In the prior art, when the patient is on the scanning bed, the magnetic resonance doctor judges the scanning position of the human body under the calibration of the magnetic resonance laser positioning through naked eye observation and personal experience, and then moves the bed for scanning. Usually, the detected object (patient) is...
