Abstract
A multi-sensor system is provided and integrated on one or more fibers, compatible with magnetic resonance (MR) imaging, capable of measuring temperature, pressure, and position during medical interventional procedures (ablation, catheter insertion into the body, etc.). The multi-sensor system includes a perforated membrane structure, a pressure measuring membrane, a semiconductor die, and a magnetic material.
Claims8
A magnetic resonance (MR) compatible multi-sensor system, comprising the following parts;
- a perforated membrane structure in a form of a perforated cap located at a distal end of the MR compatible multi-sensor system, wherein the perforated membrane structure configure blood in a vessel to contact with the MR compatible multi-sensor system, a pressure measuring membrane consisting of at least one layer of material, wherein the pressure measuring membrane is configured for measuring a pressure of blood or ambient fluid, planarly positioned on a substrate, and a diffraction grating planarly positioned thereunder to create an interference on an incident light, a semiconductor die placed planarly on a bottom of the substrate, within the perforated membrane structure, wherein the semiconductor die measures a temperature and a temperature dependence of an energy-bandgap of a semiconductor crystal, a magnetic material, wherein the magnetic material is located in the perforated membrane structure and placed on a bottom surface of the substrate on planar or prism structures with different plane angles, based on an observation of a polarization change of light reflected therefrom as a position sensor in environments where a magnetic field changes with respect to position, comprising MR imaging.
