However, the differences in false-positives and false-negatives, between the actual errors and the perceived counterparts if DSC is used, can be as high as 152 and 154, respectively, out of the 357 test set lesions.

Area-preserving mapping of 3D ultrasound carotid artery images using density-equalizing reference map

no code implementations9 Dec 2018 Gary P. T. Choi, Bernard Chiu, Chris H. Rycroft

In this work, we propose a novel method called density-equalizing reference map (DERM) for mapping 3D carotid surfaces to a standardized 2D carotid template, with an emphasis on preserving the local geometry of the carotid surface by minimizing the local area distortion.
