    A new lead-alloy test pattern allows simultaneous evaluation of gamma camera resolution, uniformity, and distortion. This method offers rapid quality control and acceptance testing for gamma imaging devices.

    Area of Science:

    • Medical Imaging
    • Nuclear Medicine Technology

    Background:

    • Gamma cameras require consistent quality control for accurate diagnostic imaging.
    • Existing methods for evaluating gamma camera performance can be time-consuming or lack comprehensive assessment.

    Purpose of the Study:

    • To develop a novel transmission test pattern for comprehensive gamma camera performance evaluation.
    • To enable simultaneous assessment of intrinsic resolution, field uniformity, and spatial distortion.

    Main Methods:

    • A high-precision lead-alloy plate with an orthogonal array of 2.5 mm diameter holes was fabricated.
    • Variable lead spacing (1.5-7 mm) was implemented along one axis to assess spatial distortion.
    • Gamma cameras were tested using Tc-99m, Xe-133, and Tl-201 radiation sources.
