    This study analyzed radionuclide computed tomography (RCT) image quality based on sampling intervals. Results show that a 6-degree interval is sufficient for accurate RCT imaging, even for dynamic scans.

    Area of Science:

    • Medical Imaging
    • Nuclear Medicine
    • Radiological Physics

    Context:

    • A multi-purpose gamma camera system with opposed detectors was installed for radionuclide computed tomography (RCT) imaging.
    • Analysis focused on the impact of angular sampling intervals on RCT image quality.

    Purpose:

    • To evaluate the variance of RCT images as a function of angular sampling interval.
    • To determine the optimal sampling interval for accurate RCT reconstruction.

    Summary:

    • Point source analysis (FWHM, FWTM) showed minimal variance across sampling intervals.
    • Uniform activity source images exhibited no detectable distortion, even at larger intervals.
    • Phantom studies revealed that sampling intervals up to 6 degrees maintained image integrity, while 9 degrees or more caused explicit distortion.

    Impact:

    • A 6-degree sampling interval is sufficient for reconstructing undistorted RCT images, contrary to theoretical predictions.
    • This finding supports the applicability of wider sampling intervals for dynamic RCT imaging, improving efficiency.
