Magnetic resonance imaging (MRI) is an important medical imaging modality because it is non-invasive and it has excellent soft tissue contrast characteristics. MRI is traditionally used to image static portions of the anatomy, or structures that mover periodically. However, many of the important potential applications of MR require real-time imaging of continuing, aperiodic motion. This includes MR guided interventions, imaging joint motion, and cardiac diagnostic imaging of patients with arrythmias.

520 $a Magnetic resonance imaging (MRI) is an important medical imaging modality because it is non-invasive and it has excellent soft tissue contrast characteristics. MRI is traditionally used to image static portions of the anatomy, or structures that mover periodically. However, many of the important potential applications of MR require real-time imaging of continuing, aperiodic motion. This includes MR guided interventions, imaging joint motion, and cardiac diagnostic imaging of patients with arrythmias.
520 $a In this thesis I propose a new real-time system architecture designed specifically for these type of applications, based on a continuous, dynamically reconfigurable real-time acquisition. This enables the development of applications with real-time data processing, interactive control and feedback. To describe this architecture I introduce the concept of virtual MRI as a means to naturally integrate different pulse sequences into a single application. The key to this model is that the applications share the magnetization, and this required the development of new techniques for managing the rapid transitions from one type of acquisition to the next without producing image artifacts.
520 $a The advantage of the virtual MRI model is that complex applications can be built up of simple building blocks, that are each programmed independently. Some of these simple blocks include continuous real-time imaging, gated high resolution imaging, device tracking, and anatomical tracking. Using these blocks several more applications have been implemented, and will be described in this thesis. One of these applications is a system for guiding a catheter when performing vascular interventions. Another application is a system for rapidly and reliably localizing and acquiring high-resolution coronary angiograms.
520 $a Finally, a new method is presented to acquire angiograms of the whole heart in a single breathhold. This fast multi-slice acquisition technique achieves excellent coverage, resolution, SNR and immunity to flow and motion.
