The commissioning of Single Photon Emission Computed Tomography (SPECT) systems, including Gamma camera components, is a critical process to ensure optimal performance and accurate diagnostic imaging. This paper outlines the comprehensive procedures for acceptance testing and quality assurance (QA) [6,7,9] of SPECT systems. Acceptance testing involves a series of standardized tests to verify that the SPECT system [1,2,3] meets the manufacturer's specifications and clinical requirements. Key parameters assessed include spatial resolution, energy resolution, sensitivity, and uniformity. Quality assurance protocols are then implemented to maintain the system's performance over time, ensuring consistent image quality and patient safety. Regular QA checks involve calibration of the Gamma camera, verification of system alignment, and assessment of image artifacts. The paper also discusses the importance of adhering to regulatory standards and guidelines to achieve reliable and reproducible results. By following these rigorous procedures, healthcare facilities can ensure the accuracy and reliability of SPECT imaging, ultimately enhancing patient care and diagnostic outcomes.
These tests are designed to be reproducible and comparable across different scanner platforms and manufacturers. The results are evaluated against the standards provided by the manufacturer and local regulatory guidelines, Atomic Energy Regulatory Board (AERB). The study emphasizes the importance of a thorough and ongoing QA program to maintain the accuracy and reliability of SPECT/CT imaging; by combining functional and anatomical imaging, SPECT/CT provides more accurate and detailed information about the location and extent of abnormalities. This is particularly useful in diagnosing conditions such as cancer, heart disease, Brain and bone disorders.
