SPECT low-field MRI system for small-animal imaging.
UNLABELLED Localization of regions with increased uptake of radiotracer in small-animal SPECT is greatly facilitated when using coregistration with anatomic images of the same animal. As MRI has several advantages compared with CT (soft-tissue contrast and lack of ionizing radiation) we developed a SPECT/low-field MRI hybrid device for small-animal imaging. METHODS A small-animal single-pinho...
متن کاملDesign of Small Animal Computed Tomography Imaging for in vitro and in vivo Studies
Introduction: Mini Computed Tomography (mini-CT) was suggested in biomedical research to investigate tissues and small animals. We present designed and built a mini x-ray computed tomography (mini-CT) for small animals as well as industrial component imaging. Materials and Methods: The system used in this study includes a X-ray tube 20kV to 160kV and a flat pa...
متن کاملUltra-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 کاملEvaluating performance of a pixel array semiconductor SPECT system for small animal imaging.
OBJECTIVES Small animal imaging has recently been focused on basic nuclear medicine. We have designed and built a small animal SPECT imaging system using a semiconductor camera and a newly designed collimator. We assess the performance of this system for small object imaging. METHODS We employed an MGC 1500 (Acrorad Co.) camera including a CdTe semiconductor. The pixel size was 1.4 mm/pixel. ...
متن کاملIntegrated 7T MRI and SPECT Systems for Small-Animal Imaging
Purpose MRI and single-photon emission computed tomography (SPECT) provide complimentary information which could aid in the diagnosis of various diseases. However, acquiring images from both modalities can been problematic. Until recently, SPECT systems could not be integrated with MRI systems due to the use of photomultiplier tubes which do not function in high magnetic fields. The development...
