Patent ID: 7809425

Claim:
Apparatus for examining a substance of a given volume, to characterize the examined substance type, the apparatus comprising: a magnetic-field applicator, for applying locally a polarizing magnetic field through the substance of the given volume, with a component defining a polarizing axis; a first sensing head, adapted for placement proximally to the substance of the given volume, the first sensoring head comprising a first main component, configured for: applying locally Radio Frequency (RF) pulses to the substance of the given volume, the RF pulses having a B component, orthogonal to the polarizing axis, such as to invoke Electrical Impedance (EI) response signals corresponding to the EI of the examined substance of the given volume, and Magnetic Resonance (MR) response signals corresponding to the MR properties of the examined substance of the given volume; detecting locally said EI response signals from the substance of the given volume; and detecting locally said MR response signals from the substance of the given volume; and a second sending head, wherein the first sensing head is configured for interacting with at least said second sensing head.
