Magnetic Resonance Imaging (MRI) is a well-established, high-resolution, non-invasive imaging technique. This project is concerned with the application of MRI to imaging of the proximal interphalangeal (PIP) finger joint, both statically and dynamically.
An existing probe had been constructed for studying finger flexation, and was modified for use with more recent hardware. A mechanism was then designed and developed for acquiring 'dynamic' images at discrete points throughout the motion of flexing the finger. As MRI can resolve the different soft tissues in a joint, the medical applications of this are manifold; both degenerative joint diseases and damage to joints can be studied using these techniques.
This report outlines the fundamental aspects of MRI and its theoretical basis in Nuclear Magnetic Resonance (NMR). The experimental procedures involved in performing the experiments are then detailed, along with the modifications and developments to the probe. The scanning sequences used to acquire different images are then described.
The images themselves are presented, emphasising their ability to contrast the different tissues and structures in the joint. The use of the images for medical applications is discussed, with examples given to highlight the use of the experimental techniques.
The project concludes that the experimental setup used was successful in obtaining both the static and dynamic images of the PIP joint, and that further development could produce a quick, powerful imaging system for diagnostic purposes.
