Patent Images
1. A respiratory measurement system, comprising:
- a plastic tube configured to be placed across a chest of the person, the plastic tube being substantially transparent to x-rays;
a plastic cord having a portion that is disposed through an interior of the plastic tube, the plastic cord being substantially transparent to x-rays;
a linear position sensor coupled to an end of the plastic cord, the end of the plastic cord being configured to be disposed away from the chest of the person, the linear position sensor generating a measurement signal indicative of an amount of linear displacement of the plastic cord during respiration by the person; and
a tabletop having a securing device and a pulley coupled thereto, wherein a first portion of the plastic cord extends between the securing device and the pulley, the securing device and the pulley being positioned on the tabletop to allow the chest of the person to be disposed between the securing device and the pulley.
