Ultra-high-resolution small- animal SPECT imaging
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 Computed Tomography (SPECT) mode. Thanks to the development of advanced multi-pinhole collimation technologies, SPECT imaging of small experimental animals is rapidly gaining in popularity. Whereas resolutions in routine clinical SP...
متن کاملTwo methods for tracking small animals in SPECT imaging
High-resolution single photon emission computed tomography (SPECT) and X-ray computed tomography (CT) imaging have proven to be useful techniques for non-invasively monitoring mutations and disease progression in small animals. A need to perform in vivo studies of non-anesthetized animals has led to the development of a small-animal imaging system that integrates SPECT imaging equipment with a ...
متن کاملFirst results from a high-resolution small animal PET insert for PET/MRI imaging
University of Manitoba, Canada We have recently completed construction of a high resolution small animal PET insert designed for operation inside a Bruker 7T MRI. The PET insert is designed to achieve a 1 mm spatial resolution in the centre of its field of view (FOV) and fit within the 114 mm inner diameter of the Bruker BGA-12S gradient coil while accommodating the Bruker 35 mm volume RF coil ...
متن کاملVery High Resolution Small Animal PET
Positron Emission Tomography (PET) is a leading technique in medical diagnostic imaging. PET scanners are used to detect cancerous cells through the use of a positron emitting tracer that is ingested by the patient. The positron annihilates with an electron in the body producing a pair of 511keV gamma rays emitted in opposite directions. The gamma rays are sufficiently energetic to leave the pa...
متن کاملHigh-efficiency, high-resolution SPECT techniques for cardiac imaging
Current standard clinical SPECT techniques provide a resolution of at best 1 cm and sensitivity in the order of 10. Performance is largely determined by the collimator. Basic geometry couples resolution and sensitivity; the problem of high-resolution imaging is a formidable one because, to image at constant Signal-to-Noise, resolution improvements must be supported by simultaneous sensitivity i...
