Title:
SURVIVAL CARDIAC MUSCLE DIAGNOSTIC APPARATUS BASED ON MAGNETIC FIELD MEASUREMENT AND METHOD FOR ANALYSING SURVIVAL CARDIAC MUSCLE
Document Type and Number:
Japanese Patent JP3712349
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a survival cardiac muscle diagnostic device and method for analyzing the survival cardiac muscles based on the magnetic field measurement capable of identifying a deranged part or a survival part of the cardiac muscles in a ventricle speedily and precisely.
SOLUTION: A magnetic field distribution measuring device 1 prepares data on the magnetic field distribution in time sequence by measuring the non-contact magnetism in plural coordinates on the region of chest of a subject. A first computing unit 2 prepares image data showing the three-dimensional electric current density distribution in the cardiac muscles in response to the magnetic field distribution measuring device 1. A second computing 3 prepares three-dimensional anatomical image data by processing plural tomographic image data separately obtained by using a tomographic diagnostic apparatus. A display device 4, receiving these data, displays an image showing the intramyocardial electric current density on the anatomical image. Therefore, the position, size, shape, and level of a deranged part or a survival part of the cardiac muscles in a ventricle can be identified easily. Further, instead of the anatomical image, an image showing a normal stimulation propagation passage can be used as a template.
