Motion Detection Methods in SPECT – A Review

Md Nahid Hossain, Kamila Afroj Quadir
2017 Bangladesh Journal of Nuclear Medicine  
<p>In SPECT, data acquisition occurs over a relatively long time. During the whole acquisition time the patient must lie still, which is very difficult.  ...  These movements cause misalignment of the projection frames and may introduce artifacts. To overcome this, motion detection and correction techniques are applied to improve image quality.  ...  Authors performed the digital and physical Hoffman phantom experiments to explore practical aspects of this approach. KJ Lee et al.  ...
