Theoretical study of lesion detectability of MAP reconstruction using computer observers.

Theoretical study of lesion detectability of MAP reconstruction using computer observers.

The low signal-to-noise ratio (SNR) in emission data has stimulated the development of statistical image reconstruction methods based on the maximum a posteriori (MAP) principle. Experimental examples have shown that statistical methods improve image quality compared to the conventional filtered bac...
