Fisher information analysis of list-mode SPECT emission data for joint estimation of activity and attenuation distribution
Md Ashequr Rahman, Yansong Zhu, Eric Clarkson +3
The potential to perform attenuation and scatter compensation (ASC) in single-photon emission computed tomography (SPECT) imaging using only the SPECT emission data is highly signi…
Image reconstruction in fluorescence molecular tomography with sparsity-initialized maximum-likelihood expectation maximization
Yansong Zhu, Abhinav K. Jha, Dean F. Wong +1
We present a reconstruction method involving maximum-likelihood expectation maximization (MLEM) to model Poisson noise as applied to fluorescence molecular tomography (FMT). MLEM i…
Application of computational breast phantoms to evaluate reconstruction methods for fluorescence molecular tomography
Yansong Zhu, Abhinav K. Jha, Arman Rahmim
Fluorescence molecular tomography (FMT) has potential of providing high contrast images for breast tumor detection. Computational phantom provides a convenient way to a wide variet…
