中文简介:
自从70年代末,随着CT扫描仪的发明,放射探测器在核和粒子物理领域的发展对医学成像产生了巨大的影响。在过去30年中,位置敏感气体探测器、与光电倍增管(PMT)和位置敏感光电倍增管(PSPMT)耦合的高z和高密度闪烁体以及固态探测器在高能物理中的大量应用引发了一系列电离辐射医学成像的新应用。遗传学和分子生物学的加速科学发展最终产生了现在所称的分子成像。这一领域的研究不仅在辐射探测器技术上提出了新的挑战,而且在ASIC电子技术、快速数字读出和并行软件方面也提出了新的挑战。在这三个系列的讲座中,我将尝试展示高能物理和医学成像的发展如何受益于这两个领域之间的研究活动的交叉融合,以及它们在未来将获得多大的优势。关于医学成像的特殊证据,我将讨论:1-气体、闪烁体和固态探测器在数字放射学和数字乳房摄影、临床CT和小动物CT中的应用。2-闪烁体和PMT/PSPMT在功能成像中的应用,尤其是:用于PET和SPEC的分子成像(临床和临床前);-用于乳腺癌成像(PEM和SPEM、PEMT和SPEMT);-用于强子疗法中的在线PET剂量测定。3-新型固态光电倍增管在医学成像中的影响和多模成像的出现,如PET/CT和SPECT/CT、PET/MRI和SPECT/MRI。
课程简介: The development of radiation detectors in the field of nuclear and particle physics has had a terrific impact in medical imaging since this latter discipline took off in late ’70 with the invention of the CT scanners. The massive use in High Energy Physics of position sensitive gas detectors, of high Z and high density scintillators coupled to Photomultiplier (PMT) and Position Sensitive Photomultipliers (PSPMT), and of solid state detectors has triggered during the last 30 years a series of novel applications in Medical Imaging with ionizing radiation. The accelerated scientific progression in genetics and molecular biology has finally generated what it is now called Molecular Imaging. This field of research presents additional challenges not only in the technology of radiation detector, but more and more in the ASIC electronics, fast digital readout and parallel software. In this series of three lectures I will try to present how high energy physics and medical imaging development have both benefited by the cross-fertilization of research activities between the two fields and how much they will take advantage in the future. With particular evidence to Medical Imaging I will address and discuss: 1 - The use of gas, scintillator and solid state detectors in digital radiology and digital mammography, clinical CT and small animal CT. 2 - The use of scintillators and PMT/PSPMTs in functional imaging and in particular: - For Molecular Imaging with PET and SPECT (clinical and preclinical); - For Breast Cancer Imaging (PEM and SPEM, PEMT and SPEMT); - For on line PET dosimetry in hadrontherapy. 3 - The impact of the novel solid state photomultipliers in Medical Imaging and the advent of multimodality imaging such as PET/CT and SPECT/CT, PET/MRI and SPECT/MRI.
