Embodiment Construction
[0050] The steps of the present invention are described in detail below in conjunction with accompanying drawings:
[0051] (1) Image acquisition:
[0052] Acquisition equipment includes a C-arm single-sided X-ray angiography machine and an intravascular ultrasound imager.
[0053] see figure 2 , IVUS and CAG imaging are performed simultaneously. Routine puncture through the right femoral artery or the brachial artery of the upper arm for selective coronary angiography. Under the guidance of the X-ray fluoroscopy image, insert the high-frequency ultrasound probe catheter to the distal end of the blood vessel. After the ultrasound probe was connected to the ultrasound imager to remove artifacts, the catheter was retracted at a constant speed and equidistant by motor control. When the probe catheter rotates 360° at 1800 r / min, real-time vascular section images of 30 frames per second are obtained continuously. The commonly used clinical method of allowing the patient to ho...
