International Classification:
A61B 5055
US Classification:
600411, 600422, 324307
Abstract:
A system and method for using magnetic resonance imaging to increase the accuracy of electrophysiologic procedures is disclosed. The system in its preferred embodiment provides an invasive combined electrophysiology and imaging antenna catheter which includes an RF antenna for receiving magnetic resonance signals and diagnostic electrodes for receiving electrical potentials. The combined electrophysiology and imaging antenna catheter is used in combination with a magnetic resonance imaging scanner to guide and provide visualization during electrophysiologic diagnostic or therapeutic procedures. The invention is particularly applicable to catheter ablation, e. g. , ablation of atrial fibrillation. In embodiments which are useful for catheter ablation, the combined electrophysiology and imaging antenna catheter may further include an ablation tip, and such embodiment may be used as an intracardiac device to both deliver energy to selected areas of tissue and visualize the resulting ablation lesions, thereby greatly simplifying production of continuous linear lesions. The invention further includes embodiments useful for guiding electrophysiologic diagnostic and therapeutic procedures other than ablation.

Abstract:
A system and method for using magnetic resonance imaging to increase the accuracy of electrophysiologic procedures is disclosed. The system in its preferred embodiment provides an invasive combined electrophysiology and imaging antenna catheter which includes an RF antenna for receiving magnetic resonance signals and diagnostic electrodes for receiving electrical potentials. The combined electrophysiology and imaging antenna catheter is used in combination with a magnetic resonance imaging scanner to guide and provide visualization during electrophysiologic diagnostic or therapeutic procedures. The invention further provides a system for eliminating the pickup of RF energy in which intracardiac wires are detuned by filtering so that they become very inefficient antennas. An RF filtering system is provided for suppressing the MR imaging signal while not attenuating the RF ablative current. Steering means may be provided for steering the invasive catheter under MR guidance.

US Classification:
600423, 600410, 600424
Abstract:
A system and method for using magnetic resonance imaging to increase the accuracy of electrophysiologic procedures includes an invasive combined electrophysiology and imaging antenna catheter which includes an RF antenna for receiving magnetic resonance signals and diagnostic electrodes for receiving electrical potentials. The combined electrophysiology and imaging antenna catheter is used in combination with a magnetic resonance imaging scanner to guide and provide visualization during electrophysiologic diagnostic or therapeutic procedures, such as ablation of cardiac arrhythmias. The combined electrophysiology and imaging antenna catheter may further include an ablation tip, and be used as an intracardiac device to deliver energy to selected areas of tissue and visualize the resulting ablation lesions. The antenna utilized in the combined electrophysiology and imaging catheter for receiving MR signals is preferably of the coaxial or “loopless” type. High-resolution images from the antenna may be combined with low-resolution images from surface coils of the MR scanner to produce a composite image.

US Classification:
378 4
Abstract:
An apparatus includes a transformation table acquiring unit, a blood-flow information acquisition unit and a blood-flow image generating unit. The transformation table acquiring unit obtains a transformation table for transforming unspecified information representing a concentration of a contrast medium in a myocardium into an unspecified blood flow value image based on a CT image acquired in a concentration transition period. The blood-flow information acquisition unit obtains information representing the concentration of the contrast medium based on a CT image acquired during a constant concentration period. The blood-flow image generating unit generates a blood flow value image based on the information representing the concentration of the contrast medium according to the transformation table.

Abstract:
A method of performing brain therapy may include placing a subject in a main magnetic field, introducing into the subject's brain a combination imaging and therapeutic probe, the probe including a magnetic resonance imaging antenna and an electrical energy application element, acquiring a first magnetic resonance image from the antenna of the combination probe, acquiring a second magnetic resonance image from a surface coil, combining the first and second magnetic resonance images to produce a composite image, positioning the combination probe within the brain with guidance from at least one of the images, and delivering electrical energy to the brain from the electrical energy application element of the combination probe thus positioned.
