Reference: 8 or 16 bins Reference information: I am not sure what this means, but it does seem to indicate something like a physical "bin" or storage place, or analagous to a physical bin. "ECG-gating problems ECG-gating problems may be suspected by reviewing the cine display of the planar projection images. Sometimes a “flashing” effect occurs, caused by brighter and darker projection images. If the heart 100 Nuclear Cardiology, The Basics rate during SPECT image acquisition was irregular, not all 8 or 16 bins of an ECG-gated SPECT study have accumulated the same number of counts per stop, resulting in darker and lighter images. However, one should be aware that ECG-gating irregularities are often subtle and may not be spotted directly from planar projection images." http://www.almhnds.com/7/NM/8.pdf from a 313 page pamphlet/book Nuclear Cardiology The Basics how to set up and maintain a laboratory |
