✦ Synopsis

Abstract

An interactive real‐time imaging system capable of rapid coronary artery imaging is described. High‐resolution spiral and circular echo planar trajectories were used to achieve 0.8 × 1.6 mm^2^ resolution in 135 ms (CEPI) or 1.13 × 1.13 mm^2^ resolution in 189 ms (spirals), over a 20‐cm FOV. Using a sliding window reconstruction, display rates of up to 37 images/sec were achieved. Initial results indicate this technique can perform as a high‐quality 2D coronary localizer and with SNR improvement may enable rapid screening of the coronary tree.

## Abstract We describe a system for performing interactive MRI in real time. Using a TR/TE 7.1/ 3.5 ms sequence, the operator may alter a scan parameter and observe the effects of the alteration on the image within a few hundred milliseconds. With this system, we can interactively control the obli
