Gamma Cameras: Exploring the Technology, Applications, and Future Prospects
Keywords:
Gamma camera, Nuclear medicine, Collimators, Scintillators, Photomultiplier tubesAbstract
Gamma cameras, pivotal in nuclear medicine imaging, provide crucial insights into the physiological functions of organs and tissues. This study delves into the technology behind gamma cameras, their applications, and future prospects. Gamma rays, high-energy electromagnetic radiation, are detected and converted into images by gamma cameras. The research combined field observations at a tertiary hospital’s Nuclear Medicine Centre with a comprehensive literature review. Direct interactions with medical professionals and observations of gamma camera procedures provided practical insights into the operational principles and clinical applications. Gamma cameras, evolving from early scintillation counters to modern digital detectors, consist of key components like collimators, scintillators, photomultiplier tubes, and advanced imaging software. These devices are integral in diagnosing and monitoring conditions in cardiology, oncology, neurology, endocrinology, and orthopedics. Technological advancements, such as solid-state detectors, multi-pinhole collimators, and AI-enhanced image processing, have significantly improved image quality, diagnostic accuracy, and patient safety. Future prospects include personalized medicine, molecular imaging, AI and machine learning integration, multi-modal imaging, and theranostics, promising enhanced diagnostic precision and treatment outcomes. This study underscores the evolving capabilities of gamma cameras and their indispensable role in modern healthcare.
