Fig. 3From: Convolutional neural network-based automatic heart segmentation and quantitation in 123I-metaiodobenzylguanidine SPECT imagingRelationship of average heart counts calculated from SPECT images using CNN and from conventional early and late planar images. SPECT HCNN vs. planar HBC (A), planar H (B), and planar HMR (C). Red circles and blue squares, early and late images, respectively. Shaded area, confidence of fit.Back to article page
