Attenuation correction with region growing method used in the positron emission mammography imaging system
Attenuation correction with region growing method used in the positron emission mammography imaging system
The Positron Emission Mammography imaging system (PEMi) provides a novel nuclear diagnosis method dedicated for breast imaging. With a better resolution than whole body PET, PEMi can detect millimeter-sized breast tumors. To address the requirement of semi-quantitative analysis with a radiotracer concentration map of the breast, a new attenuation correction …
