Arrangement and method for detecting inconsistencies and abnormalities in a body

摘要

A system for detecting abnormalities or inconsistencies and a method to utilize the same are provided. In particular, a computer system may be adapted to detect the abnormality or inconsistency within at least a portion of a subject by generating internal impedance data which indicates that an impedance change within the portion of the subject has occurred. For example, the impedance change may be associated with a change in at least one characteristic of a blood vessel within the subject (such as a change in a fluid flow rate within at least a portion of the subject), a change in a fluid volume within at least a portion of the subject, etc. The impedance change also may be associated with the presence of a foreign object within the portion of the subject. In an exemplary embodiment, it is possible to detect the abnormality or inconsistency within the subject by generating a continuous, real time internal impedance map indicating the impedance change within the subject. Alternatively, the abnormality or inconsistency may be detected within the subject by generating a plurality of static internal impedance maps which indicate that the impedance change within the subject has occurred.

1. A system for the detection of stroke in a subject, the system comprising:
an electrical stimulator configured to apply a current comprised of pink noise to at least one pair of electrodes, the electrodes configured to be positioned on a skull of the subject to apply the current and to receive brain activity of the subject; an analog to digital (A/D) converter configured to record the brain activity of the subject in the form of spectral electrical impedance tomography recordings and electroencephalography recordings, simultaneously; and a computer system configured to generate real time spectral electrical impedance data from the spectral electrical impedance tomography recordings, the spectral electrical impedance data indicating an impedance change within the brain of the subject, wherein the impedance change is associated with an indication of stroke.
