DOI: 10.1002/acm2.70254

Abstract: Abstract Purpose The most appropriate 4DCT image for radiomics analysis remains uncertain, with options including individual respiratory phases and motion‐compensated (MC) reconstructions. This study compares radiomic features derived from MC reconstructions and patient‐specific, 4D phases,… read more here.

recommendations! Published in 2019 at "IEEE Robotics and Automation Letters"

DOI: 10.1109/lra.2019.2932865

Abstract: The essence of most shape registration algorithms is to find correspondences between two point clouds and then to solve for a rigid body transformation that aligns the geometry. The main drawback is that the point… read more here.
