Tumor volume delineation plays a critical role in radiation treatment planning and simulation. Inaccurately defined target volume may lead to overdosing of normal structures surrounding the tumor, while potentially underdosing cancerous tissue. Conve

Properties of Noise in Positron Emission Tomography Images Reconstructed with Filtered-Backprojection and Row-Action Maximum Likelihood Algorithm

Autor: Don Robinson, Hans-Sonke Jans, T. Riauka, A. R. Teymurazyan

Publikováno v: Journal of Digital Imaging. 26:447-456

Noise levels observed in positron emission tomography (PET) images complicate their geometric interpretation. Post-processing techniques aimed at noise reduction may be employed to overcome this problem. The detailed characteristics of the noise affe
