    Advancements in emission tomography equipment, including single-gamma and positron imaging, are rapidly evolving. New technologies like rotating slant-hole collimators and cesium fluoride detectors with time-of-flight offer improved resolution and clinical utility.

    Area of Science:

    • Medical Imaging
    • Nuclear Medicine
    • Diagnostic Technology

    Background:

    • Emission tomography equipment is rapidly advancing for both single-gamma and positron detection.
    • Existing technologies like the 7-pinhole collimator have limitations that newer methods aim to overcome.

    Purpose of the Study:

    • To review the current state and future prospects of emission tomography equipment development.
    • To highlight advancements in single-gamma and positron imaging technologies.

    Main Methods:

    • Review of current and emerging technologies in emission tomography.
    • Comparison of different collimator designs (7-pinhole, rotating slant-hole) and detector materials (BGO, CsF).

    Main Results:

    • Rotating slant-hole collimators offer advantages over the 7-pinhole method for single-gamma tomography.
