摘要：Currently MRI is extensively used in medical analysis to produce high-eminence images for its a variety of useful features, such as high-resolution potential, subjective anatomic cross-sectional image, and high tissue contrast. In habitual magnetic resonance imaging the presence of artifacts in images is a part of the practice, few are readily identified and others can be interpreted as pathology. So it is key to recognize where they appear in the image. In order to generate an image, each sample in the image is spatially encoded by a series of gradients. In MRI the problems such as time delay, blurring and shadowing can arise in ZTE due to the presence of imaging gradient. To decipher these problems a single point imaging is used similar as in PETRA and allowed high peak power for short pulse duration. Nevertheless, peak power and SAR limitations impose practical limits for in vivo scanning of humans. So a new method is proposed to resolve above problems. In this proposed work the ZTE sequence signal is used which include the imaging profile which is obtained by modulate the samples with phase and efficient algorithms is used for correcting the artifacts in ZTE imaging. The proposed work is simulated by using MAT LAB tool on MRI Images.
