Abstract

A magnetic resonance imaging (MRI) machine is used to acquire two-dimensional (2D) images of a patient's joint, which are used to generate a three-dimensional (3D) model of the joint. To acquire the 2D images, the patient is installed on a table associated with the MRI machine and a coil is applied to a scan region. A fat-saturation pulse sequence is used to acquire images of the joint.
