WebPolar map samples derived from the raw images by the standard algorithm were used to generate raw polar maps showing radiotracer count distributions normalized to the maximal counts. SPECT images were quantified by sex-specific normal limits deriving upright and supine blackout and total perfusion deficit (TPD) maps—4 polar maps in total (8,13). WebNov 11, 2024 · Polar maps were post-processed (GE Healthcare Xeleris®) and exported in.tiff format with matrix size 175 x 175. So, we generated 02 polar maps (stress/rest) for female patients and 03 (stress/rest/prone) for male patients. We did not use the clinical data for the ML algorithms, but the image attributes such as pixel position and intensity.
