An Improved Method for Photoacoustic Image Reconstruction Based on Wavelet Denoising and Deconvolution Calculation
Photoacoustic image reconstruction is widely used as a nondestructive image reconstruction method because it has high contrast like optical imaging and high resolution like ultrasonic imaging.Aiming at the problems of noise pollution and impulse response in the process of time reversal photoacoustic imaging,a model used to collect photo-acoustic pressure is built.Wavelet soft threshold denoising method and deconvolution calculation are jointly used to re-move noise and effect of the sensor impulse response.The experimental results prove that this new method can remove noise and artifacts in the reconstructed photoacoustic image effectively and visual effects of the reconstructed photo-acoustic image are significantly improved.
