Phase Space Analysis in MRI

An MRI is a device used to physically calculate the continuous Fourier transform of an image. The challenge in MRI is to use this data to reconstruct an image of the body. I'll discuss how phase space analysis can be used to improve the imaging process. I'll introduce wavefront filters, an extension of concentration kernels to multiple dimensions. I'll then show how they can be used to match a parametric model of an image to physical data, and discuss future directions in improving imaging.
