Abstract: A magnetic resonance (MR) coil assembly includes a first row of coil elements, wherein the first row is a curved row and configured to conform to a first body curvature in a cone shape when the first row is bent and wrapped around the first body curvature; and a second row of coil elements, wherein the second row is a straight row and configured to conform to a second body curvature in a cylinder shape when the second row is bent and wrapped around the second body curvature, wherein each coil element in the first row has a first area and each coil element in the second row has a second area, and wherein the first area is larger than the second area. The first curved row can also be deployed without a second curved row.

Abstract: A method of entropy-based image registration comprising estimating conditional probability distribution functions (PDFs) between two images as multivariate Gaussian distributions; mathematically relating an entropy of the multivariate Gaussian distributions to a sum of square differences (SSD) between the images; and optimising the registration between the images utilising a cost function based on the SSD.
