Ultrasonic image reconstruction and image guide acquisition method, device, system and terminal

Abstract

The invention provides an ultrasonic image reconstruction and image guide acquisition method, device and system and a terminal. Firstly, a transducer is excited to generate single-angle plane wave ultrasound to irradiate a prostate to obtain an ultrasonic RF signal. Then, based on the medical image of the prostate and the ultrasonic RF signals, a static flow ultrasonic simulation image and a real-time ultrasonic image are reconstructed, and an accurate guide control instruction is generated accordingly. These instructions can direct the transducer to move to an optimal imaging position and then release a pulsed laser to irradiate the prostate, thereby capturing a photoacoustic RF signal. Based on the acquired photoacoustic RF signals, a photoacoustic image is further reconstructed, and the signals are properly stored. Visual conformal ultrasonic irradiation on the prostate is achieved through the designed real-time image guiding function, accurate collection of ultrasonic and opto-acoustic RF signals is ensured, the reconstruction accuracy of ultrasonic and opto-acoustic images is further remarkably improved, the accuracy of intelligently judging the prostate inflammation degree of a patient is further improved in an auxiliary mode, and the treatment efficiency is greatly improved.
