MRI THERMOGRAPHY FOR CARDIAC LESION ASSESSMENT

摘要

Described embodiments include an apparatus that includes anelectrical interface and a processor. Theprocessor isconfigured to receive via the electrical interface, from aplurality of sensors, a first signal that indicates a locationof an intrabody tool inside a body of a subject, and a secondsignal that indicates a phase, of a physiological motion cycleof the subject, at which the first signal was acquired. Theprocessor is further configured to acquire, using a magneticresonance imaging (MRI) scanner, a set of multiple images at thelocation indicated by the first signal, over a portion, of asubsequent physiological motion cycle of the subject, thatincludes the phase indicated by the second signal. Otherembodiments are also described.
