Step 3) is delayed time when step 1) is carried out and is triggered the forward looking transducer annular array of transducer front end, makes forward sight ring configuration transducer form the ultrasonic scanning sound field of a preceding apparent direction;
The ultrasonic array element receiving step 3 of each forward sight of step 4)) ultrasound echo signal in, the intravascular ultrasound imaging system obtains the imaging data of this scanning direction in the forward sight visual field;
Step 5) repeating step 3) and step 4), through changing the direction that the array element time-delay changes the scanning acoustic beam, until data acquisition and the transmission of accomplishing whole cross section, forward looking transducer the place ahead;
Step 6) is according to the view data in the step 5), judges obstruction, the narrow situation of front end blood vessel, and whether definite conduit advances or retreat;
Step 7) is removed through returning of conduit or to advance, and makes the whole energy transducer position backward or the preceding segment distance that moves, and repeats above-mentioned steps 1)-step 6) obtains two two-dimensional section images in addition;
Step 8) repeating step 6) and step 7), obtain the corresponding two-dimensional section image of each diverse location of one section blood vessel, these two-dimensional section image integrations are become 3-D view until completion.
Compared with prior art, the advantage of technical scheme of the present invention is:
Endovascular double-view field supersonic imaging device provided by the invention adopts ring battle array side-looking transducer to combine with the phased array forward looking transducer, can not only be to the imaging of blood vessel sidewall, and the while can also be to apparent direction imaging before the blood vessel.Can obtain the image of the several centimetres of degree of depth as required along the blood vessel axial distal end, with the demonstration unstable spot, and can the more convenient structure that shows blood vessel wall all sidedly.The blood vessel far-end that the intravascular ultrasound device that utilizes side-looking and forward sight to combine can be seen the lesion vessels that front end is tortuous or entirely shut; More help the grasp of doctor to the sufferer blood vessel state; Formulate the scheme of suitable operative treatment; And can the front end vascular condition be provided in real time in the treatment of intervene operation, play the effect of navigating in the art.
