Geometric accuracy of low-dose CT scans for use in shoulder musculoskeletal research applications

•All low dose protocols resulted in a > 70 % reduction in the effective dose.•Geometric errors increased as effective dose decreased.•Error magnitudes were generally small (70 % reduction in the effective dose. Lower dose scans resulted in higher geometric errors; however, error magnitudes were g...
