| Charge | This Task Group is charged with developing standard methods for measuring the noise-power spectrum (NPS) of spatiotemporal x-ray imaging (e.g., x-ray fluoroscopy), emphasizing practical experimental methodology that is:
(a) applicable to a broad range of spatiotemporal imaging technologies (e.g., x-ray image intensifiers and flat-panel detectors), and
(b) mindful of general, theoretical considerations regarding the multi-dimensional image NPS as described by the parent Working Group, including:
- dimensionality and normalization of the resulting 3D (spatiotemporal)NPS
- factors affecting correlation in spatiotemporal image data (e.g., image lag)
- extension to analysis of the 3D (spatiotemporal) noise-equivalent quanta (NEQ).
A Task Group Report will be produced to communicate practical standards for spatiotemporal NPS measurement. Sample code implementing methods is highly recommended. |
