In recent years, nuclear medicine has undergone significant technological advances with the introduction of digital cameras based on the use of semiconductor detectors. In single-photon emission computed tomography (SPECT), this technology was first introduced on dedicated cardiac CzT cameras. More recently, 360° CzT cameras with extended field-of-view have been developed to enable whole-body tomographic explorations. Similarly, the cameras used in positron emission tomography (PET) have undergone a transition to digital technologies thanks to the use of new SiPM-based detectors. This work has allowed for the evaluation of the performance of these digital SPECT and PET cameras in nuclear medicine, within the field of clinical and preclinical oncology. We have thus demonstrated the improvements in sensitivity, energy resolution, and image contrast achieved through the use of 360° CzT cameras compared to conventional Anger cameras. Additionally, we demonstrated the feasibility of using this type of camera developed for humans, to perform preclinical imaging in small animals. Furthermore, we have evaluated SiPM-based PET cameras using phantoms for potential preclinical applications. We have thus measured performance approaching that obtained with dedicated microPET cameras, enabling simultaneous imaging of four animals, and demonstrated the ability to perform accurate quantification in preclinical oncology

To overcome the Anger camera spatial resolution/sensitivity trade-off, the HiSens architecture has been studied for several years. This architecture, based on pixelated CZT detectors, takes advantage of the accurate 3D localization of the interactions inside the detector. This work is dedicated to this architecture. First, a quantification methodology is introduced. This step allows preliminary simulation-based and experimental evaluation of the architecture in planar acquisition mode. A DQE (Detective Quantum Efficiency) calculation tool, aiming at optimizing the HiSens parameters in planar acquisition mode, is then proposed and used for two applications (cardiac imaging and scintimammography). Lt shows that, considering a 5 cm source-collimator distance, the system sensitivity can be increased by 3 while maintaining or improving the spatial resolution thanks to the HiSens architecture. Ln this study, the collimator-to-detector distance parameter is made scalable. We show that its adjustment can advantageously increase the high frequency content of the reconstructed images. The effect of this parameter is experimentally validated in this work and has been besides patented. Finally, a SPECT DQE calculation tool is developed. This one, permitting to describe the system performances inside the field-of-view, is used, at the end of the work, to suggest a methodology allowing to determine the optimal collimation parameters for cardiac SPECT applications

Myocardial single-photon emission computed tomography (SPECT) is considered as the gold standard for the diagnosis of coronary artery disease. Developed in the 1980s with rotating Anger gamma-cameras, this technique could be dramatically enhanced by new imaging systems working with semi-conductor detectors. Two semiconductor cameras, dedicated to nuclear cardiology and equipped with Cadmium Zinc Telluride detectors, have been recently commercialized: the Discovery NM- 530c (General Electric) and the DSPECT (Spectrum Dynamics). The performances of these CZT cameras were compared: 1) by a comprehensive analysis of phantom and human SPECT images considered as normal and 2) with the parameters commonly recommended for SPECT recording and reconstruction. The results show the superiority of the CZT cameras in terms of detection sensitivity, spatial resolution and contrast-to-noise ratio, compared to conventional Anger cameras. These properties might lead to dramatically reduce acquisition times and/or the injected activities. However, the limits of these new CZT cameras, as well as the mechanism of certain artefacts, remain poorly known. That?s why we developed, with the GATE Monte Carlo simulation plateform, a specific simulator of the DSPECT camera. We validated this simulator by comparing actually recorded data with simulated data. This simulator may yet be used to optimize the recorded and reconstruction processes, especially for complex protocols such as simultaneous dual-radionuclide acquisition and kinetics first-pass studies
