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 method based on a three-dimensional seeded region growing image segmentation (3DSRG-AC) method has been developed. The method gives a 3D…

PEMi has a number of advantages over conventional PET screening, such as detection of minute lesions, accurate lesion localization and biopsy guidance, and has a better resolution in detection of millimeter-sized breast tumors.

Attenuation correction for a combined 3D PET/CT scanner.

The proof of principle of CT-based attenuation correction of 3D positron emission tomography (PET) data is demonstrated by using scans of bone and soft tissue equivalent phantoms and scans of humans to conclude that using CT information is a feasible way to obtain attenuation Correction factors for 3D PET.

Real-time viewer for Positron Emission Mammography image-guided intervention

Simulation based on real clinical data shows that the localization of lesions can be obtained almost real-time and even relatively faint lesions with a lesion to background ratio of 2:1 can be localized in 10 seconds.

The segmentation of liver and vessels in CT images using 3D hierarchical seeded region growing

A novel 3D hierarchical SRG algorithm which learns its homogeneity criterion automatically and can efficiently segment the live region and vessels from serial abdominal CT images with little user interaction is developed.

Exact and approximate rebinning algorithms for 3-D PET data

This paper presents two new rebinning algorithms for the reconstruction of three-dimensional (3-D) positron emission tomography (PET) data that are approximate but allows an efficient implementation based on taking 2-D Fourier transforms of the data.

An EM algorithm for estimating SPECT emission and transmission parameters from emission data only

EM-IntraSPECT provided more uniform estimates of cardiac activity in the physical phantom study and in the simulation study with tight support, but less uniform estimates with a broad support, and the new EM algorithm derived here has additional applications, including reconstructing emission and transmission projection data under a unified statistical model.

Accelerated image reconstruction using ordered subsets of projection data

Ordered subsets EM (OS-EM) provides a restoration imposing a natural positivity condition and with close links to the EM algorithm, applicable in both single photon (SPECT) and positron emission tomography (PET).
