Apparatus and method for heart size measurement using microwave doppler radar

1. A method of determining a characteristic of an object within a patient, comprising:

transmitting an electromagnetic radiation signal into the patient through each of at least a plurality of signal transceivers connected together as a conformable semi-rigid unit while the conformable semi-rigid unit is spaced apart from the patient, such that the signal transceivers are moveable relative to an outer surface of the patient through which the characteristic of the object is measured;

receiving signals reflected off of the object; and

determining the characteristic of the object based on the reflected signals,

wherein the electromagnetic radiation is microwave radiation.

2. The method according to claim 1 , wherein a Doppler effect observed from the signals transmitted by the at least a plurality of the signal transceivers and the reflected signals are used in determining the characteristic of the object.

3. The method according to claim 1 , further comprising:

forming the conformable semi-rigid unit in a semi-rigid shape in accordance with at least one contour of the patient.

4. An object measurement apparatus, comprising:

an array of individual signal transceivers connected together as a conformable semi-rigid unit, the array of individual signal transceivers configured to measure, via electromagnetic radiation, a characteristic of an object situated within a patient while the object measurement apparatus is spaced apart from the patient, such that the signal transceivers are moveable relative to an outer surface of the patient through which the characteristic of the object is measured; and,

wherein the array is built into a bed,

wherein the electromagnetic radiation is microwave radiation.

5. An object measurement apparatus, comprising:

an array of individual signal transceivers connected together as a conformable semi-rigid unit, the array of individual signal transceivers configured to measure, via electromagnetic radiation, a characteristic of an object situated within a patient while the object measurement apparatus is spaced apart from the patient, such that the signal transceivers are moveable relative to an outer surface of the patient through which the characteristic of the object is measured, and,

wherein the array is built into of a chair,

wherein the electromagnetic radiation is microwave radiation.

6. An object measurement apparatus, comprising:
