Abstract

A device for noninvasively measuring energy emissions in the human chest. This device includes first and second spaced longitudinal flexible supports. At least one transverse support means extends between the said first and second spaced longitudinal supports. A plurality of sensor means positioned in a spaced transverse array on the transverse support. This device is an array based measurement system that minimizes the effect of rib interaction on the space-time field of the human thorax. This array-based measurement system is noninvasive so there is almost no patient risk.

Claims

1. A device for noninvasively measuring energy emissions in the human chest comprising:

first and second spaced longitudinal flexible supports;

at least one transverse support means having a first terminal end and a second terminal end, the first terminal end being positioned on the first spaced longitudinal flexible support and the second terminal end being positioned on the second spaced longitudinal flexible support; and

a plurality of sensor means positioned in a spaced array on the transverse support means wherein said plurality of sensor means comprise sensors selected from strain gauges, accelerometers, velocimeters, stress sensors, pressure sensors and displacement sensors.

2. The device of claim 1 wherein said at least one transverse support comprises a plurality of transverse support means and, each of the transverse support means is longitudinally spaced from said other transverse support means.

3. The device of claim 2 wherein each of the transverse support means can be angularly disposed with respect to the other of said plurality of transverse support means.

4. The device of claim 1 wherein the transverse support means is longitudinally displaceable on the first and second longitudinal flexible supports.

5. The device of claim 1 wherein the first and second spaced longitudinal flexible supports are respectively first and second flexible rods.

6. The device of claim 5 wherein the first and second terminal ends are disposed on the first and second flexible rods by first and second collars.

7. The device of claim 6 wherein the first and second collars are equipped with fastening means which may be loosened to allow each collar to be independently moved along the first and second flexible rods.

8. The device of claim 1 further comprising:

a rigid frame; and

said first and second spaced longitudinal flexible supports each having two opposed ends, and each said end being mounted to said rigid frame.

9. The device of claim 8 wherein said rigid frame is curved for conforming with the human chest.
