Potential applications of HDR in echocardiography

The diagnostic process in medicine in many cases depends on readability of medical images. Thus, the image enhancement is very important step in medical imaging. We investigate the potential application of High Dynamic Range (HDR) imaging in echocardiography. HDR image is generated using two Low Dynamic Range (LDR) echocardiograms. Since many devices can display only limited range of luminous intensity, the dynamic range of input HDR image needs to be reduced. This is done by operation called tone mapping. Several HDR tone mapping methods are analyzed and the results are presented in the paper.
