Recently, we launched a stationary SPECT system (U-SPECT-I) dedicated to small-animal
imaging. A cylinder with 75 gold micropinhole apertures that focus on a mouse organ was …

A major advance in biomedical science and diagnosis was accomplished with the
development of in vivo techniques to image radiolabeled molecules, but limited spatial …

We present a new rodent SPECT system (U-SPECT-II) that enables molecular imaging of
murine organs down to resolutions of less than half a millimeter and high-resolution total …

SPECT with submegabecquerel amounts of tracer or subsecond time resolution would
enable a wide range of new imaging protocols such as screening tracers with initially low …

Today, PET and SPECT tracers cannot be imaged simultaneously at high resolutions but
require 2 separate imaging systems. This paper introduces a Versatile Emission Computed …

Exciting new SPECT systems can be created by combining pinhole imaging with compact
high-resolution gamma cameras. These new systems are able to solve the problem of the …

Single photon emission computed tomography (SPECT) is an important technology for
molecular imaging studies of small animals. In this arena, there is an increasing demand for …

With Single Photon Emission Computed Tomography (SPECT), images of minute
concentrations of tracer molecules can be acquired, allowing in vivo molecular imaging. For …

Pinhole collimation of gamma rays to image distributions of radiolabeled tracers is
considered promising for use in small animal imaging. The recent availability of transgenic …

Today the majority of clinical molecular imaging procedures are carried out with single-
photon emitters and gamma cameras, in planar mode and single-photon emission …
