A Wavelet Algorithm in Penetrated Radial Computerized Tomography
Wavelet inversion can make up for the deficiencies of radon inversion which will lost a lot of details and improve the accuracy of CT to achieve a more accurate understanding of the internal structure of objects and provide a more precise algorithm for the early detecting the lesions and predicting the geological structure and geological density, so it has a broad application in the medical, geological prospecting and nondestructive testing. The paper applies wavelet inversion cross-well geologic computerized tomography, proposes convolved reconstruction arithmetic of wavelet that can applies to cross-well geologic computerized tomography, and constructs a discrete wavelet transform and reconstruction algorithm of Computerized Tomography image.. In actual application, this algorithms iterative time will be less, speed will quicken. It excels the traditional Radon transforms construction algorithm and it can be realized by computer language program. The experimental results prove that the algorithm has many advantages such as quick speed, accurate details in reconstructing image and so on, and its effect is good in geological computerized tomography.
