Embodiment
[0038] The magnetic resonance image data collected in this embodiment is a contrast agent-enhanced T1-weighted image of the abdomen of a human body, and the data comes from a GE1.5T magnetic resonance imager.
[0039] Step 1: Acquisition of a contrast agent-enhanced T1-weighted magnetic resonance image of human subcutaneous tissue by using magnetic resonance imaging technology. The imaging sequence used is a gradient echo sequence with fat signal suppressed, and its imaging parameters are as follows: recovery time is 6.064 ms, echo time is 2.92 ms, dump angle is 15 degrees, observation field is 480*480 mm, slice thickness is 3mm, the scanning matrix is 512*512. The image display tool used is OsiriX software.
[0040] Step 2: Select a reference point and mark the perforator flap vessels.
[0041] In this embodiment, the navel in the abdomen of the human body is selected as the reference point, and three perforating flap vessels are found and marked on the left side of the a...
