MAGNETIC ENHANCEMENT IN DETERMINATION OF PHYSIOLOGICAL BLOOD PARAMETERS
First Claim
1. A system for measuring a physiological parameter of blood in a patient, the system comprising:
- a magnetic array configured to have tissue of the patient inserted therein and establish in the tissue an axial magnetic field and a radial magnetic field perpendicular to the axial magnetic field;
an emitter configured to emit a first optical signal into the tissue during a first angular configuration between the emitter and the magnetic array, and emit a second optical signal into the tissue during a second angular configuration between the emitter and the magnetic array;
a detector configured to detect characteristics of the first optical signal and the second optical signal; and

Abstract
Systems and methods for measuring a physiological parameter of blood in a patient are provided herein. An example method includes establishing with a magnetic array, an first magnetic field along tissue of the patient inserted into the magnetic array and a second magnetic field perpendicular to the tissue, emitting optical signals into further tissue of the patient during at least a first alignment of the magnetic array around the tissue, detecting characteristics of the optical signals, and identifying a value of a physiological parameter based on at least the characteristics of the optical signals.
