Spect polar map deep learning

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. WebDespite the above limitations, the results of the present work reveal the possible applications of deep learning for polar map images classification in SPECT myocardial perfusion imaging. These findings suggest that our approach can be a promising alternative to routine polar map analysis using normal databases to further support the clinical ...
