Title:
METHOD AND DEVICE FOR CHECKING INTERNAL CONSTRUCTION OF BODY
Document Type and Number:
Japanese Patent JPS54154366
Kind Code:
A
Abstract:
Determining the internal structure of a body, for example, a human body, by means of an electric field which extends between individual electrodes of an electrode array which at least partly surrounds the body. Each time the value of the currents flowing through the individual electrodes is measured. From the currents electrical resistance values in individual tubes of flux generated between the electrodes are measured. By exposure of the body successively to electric fields which each have a different direction and by measurement of the resistance values then occurring, the specific resistance in individual elements of a matrix which is imagined to be stationary with respect to the body can be determined. From the given distribution of the specific resistance in the elements of the matrix, resistance values are calculated in all tubes of flux successively at least once for each field direction. For determination of a correction for the specific resistance in the elements of the matrix, the calculated resistance values are compared with the measured resistance values. The magnitude of the difference determines the magnitude of the correction.
