This paper proposes to develop the image segmentation method by appraising the various image analysis techniques. The effective method had been examined and degree of justification was carried out in various clinical concerns. Currently, we scrutinize a classification of methodology in terms of previous data. New ideas had been obtained from additional papers and demonstrated about clinical efficiency...
Ultrasound imaging is used as the primary imaging modality for diagnosis of renal calculus. Speckle noise and shadows present in ultrasound images makes the identification of kidney stones very complex and challenging. Therefore despeckling of ultrasound images is carried out as a preprocessing step. The preprocessing of kidney ultrasound images consists of denoising using wavelet thresholding method...
The current clinically available procedure for non-invasively treating renal calculi, extracorporeal shock wave lithotripsy (ESWL), suffers from the fact that it can result in incomplete fractionation of the stone and confer damage to both renal and extra-renal tissues. We assessed the feasibility of using histotripsy to non-invasively erode kidney stones to fine debris and performed a comparison...
Time-reversal invariance, a fundamental symmetry that holds nearly everywhere in microscopic physics, can be exploited in a unique way in acoustics, to create a variety of useful instruments. In the past years, taking advantage of the reversibility of the acoustic propagation that holds in many situations (to the extent that everything is adiabatic) time reversal mirrors (TRMs) have been developed...
