Evaluation of penalty design in penalized maximum-likelihood image reconstruction for lesion detection.

Published in Journal of Medical Imaging

Detecting cancerous lesions is a major clinical application in emission tomography. Previously, we developed a method to design a shift-variant quadratic penalty function in penalized maximum-likelihood (PML) image reconstruction to improve the lesion detectability. We used a multiview channelized Hotelling observer (mvCHO) to assess the lesion det...

Comparison of two-dimensional and three-dimensional iterative watershed segmentation methods in hepatic tumor volumetric...

Published in Medical Physics

In this work the authors compare the accuracy of two-dimensional (2D) and three-dimensional (3D) implementations of a computer-aided image segmentation method to that of physician observers (using manual outlining) for volume measurements of liver tumors visualized with diagnostic contrast-enhanced and PET/CT-based non-contrast-enhanced (PET-CT) CT...
