Objective: Detector designs for small animal scanners are currently dominated by discrete
crystal implementations. However, given the small crystal cross-sections required to obtain …

Positioning algorithms for scintillation cameras are investigated. Maximum Likelihood (ML)
estimation techniques and centroid-based methods (eg, weighted and local centroid) are …

Noninvasive methods for measuring the pharmacokinetics of chemotherapeutic drugs such
as 5-fluorouracil (FU) are needed for individualized optimization of treatment regimens. PET …

The spectroscopic radiation portal monitor (SPM) is widely used for homeland security. Many
research groups are studying the radionuclide identification method which is one of the …

The aim of this study was to design a multipinhole (MP) collimator with lead vertical septa
coupled to a high-resolution detector module containing silicon drift detectors (SDDs) with an …

This work reports on performance characteristics of a second generation micro crystal element
(MiCE2) detector for a dedicated PET system to image mice. Our MiCE2 detector consists …

Dual-energy x-ray absorptiometry (DXA) is the noninvasive method to diagnose osteoporosis
disease characterized by low bone mass and deterioration of bone tissue. Many global …

Statistically based iterative algorithms such as maximum likelihood–expectation maximization
(ML-EM) are used for image reconstruction in single photon emission computed …

A spectrum of a radio isotope (RI) contains a single or multiple photo-peaks and radio-activities
of all energy levels. These characteristics of each RI source are measured by radiation …

In-beam positron emission tomography (PET) is a clinically proven imaging technique for
the online investigation of position emitters induced by hadron irradiation. Because the PET …
