1.
Caucci L, Liu Z, Jha A, Han H, Furenlid L, Barrett H
Phys Med Biol
. 2019 Aug;
64(18):185007.
PMID: 31470417
Imaging systems are often modeled as continuous-to-discrete mappings that map the object (i.e. a function of continuous variables such as space, time, energy, wavelength, etc) to a finite set of...

Furenlid L, Hesterman J, Barrett H
IEEE NPSS Real Time Conf
. 2016 Apr;
2005:498-501.
PMID: 27066595
We have developed modular gamma-ray cameras for biomedical imaging that acquire data with a raw list-mode acquisition architecture. All observations associated with a gamma-ray event, such as photomultiplier (PMT) signals...

Furenlid L, Moore J, Freed M, Kupinski M, Clarkson E, Liu Z, et al.
IEEE Nucl Sci Symp Conf Rec (1997)
. 2015 Dec;
2008:1407-1410.
PMID: 26617457
We are exploring the concept of adaptive multimodality imaging, a form of non-linear optimization where the imaging configuration is automatically adjusted in response to the object. Preliminary studies suggest that...

Phys Lett A
. 2015 Nov;
26(6):217-218.
PMID: 26594086
Ultrasonic velocity measurements in KTaO between 2° and 300°K are reported. No evidence for a phase transition was observed.

Moore S, Hunter W, Furenlid L, Barrett H
IEEE Nucl Sci Symp Conf Rec (1997)
. 2015 Nov;
5:3691-3694.
PMID: 26568677
We present a simple 3D event position-estimation method using raw list-mode acquisition and maximum-likelihood estimation in a modular gamma camera with a thick (25mm) monolithic scintillation crystal. This method involves...

Kastis G, Wu M, Balzer S, Wilson D, Furenlid L, Stevenson G, et al.
IEEE Nucl Sci Symp Conf Rec (1997)
. 2015 Nov;
49(1):172-175.
PMID: 26568676
We have developed a high-resolution, compact semiconductor camera for nuclear medicine applications. The modular unit has been used to obtain tomographic images of phantoms and mice. The system consists of...

IEEE Nucl Sci Symp Conf Rec (1997)
. 2015 Nov;
47(4):1399-1403.
PMID: 26568675
High-spatial-resolution solid-state detectors being developed for gamma-ray applications benefit from having pixel dimensions substantially smaller than detector slab thickness. This leads to an enhanced possibility of charge partially spreading to...

IEEE Nucl Sci Symp Conf Rec (1997)
. 2015 Nov;
3:1826-1829.
PMID: 26568673
We demonstrate, using computer models, the feasibility of a new SPECT system for imaging small animals such as mice. This system consists of four modular scintillation cameras, four multiple-pinhole apertures,...

Phys Rev
. 2015 Sep;
154(3):877-886.
PMID: 26366015
The interaction of two longitudinal ultrasonic waves to produce sum- and difference-frequency waves has been studied experimentally and theoretically. These interactions are closely analogous to the type of three-phonon interactions...

PMID: 26347027
Maximum-likelihood estimation methods offer many advantages for processing experimental data to extract information, especially when combined with carefully measured calibration data. There are many tasks relevant to x-ray and gamma-ray...
