Abstract
A method of analyzing breathing data representing a shape of the trunk of a subject 104 as a function of time to monitor and/or analyze the subject's breathing pattern. The data is measured and processed into a data array relating to a 2-dimensional grid having grid points, a position in space of the shape at each grid point and points of time. The method includes the steps of mapping the data array onto a 2-dimensional array, decomposing the 2-dimensional array and forming a signature of the subject 104 from the decomposed 2-dimensional array representing a motion pattern.
Claims20
A method, comprising:
- performing an external optical measurement of a three-dimensional shape of a body of a subject over time, thereby obtaining measurement data;
- processing the measurement data to produce a data array of at least three dimensions representing a shape of at least part of the body of the subject as a function of time, the data array relating to a two-dimensional grid having grid points, a position in space of the shape at each grid point and points of time,
- mapping the data array onto a two-dimensional array,
- decomposing the two-dimensional array, and
- forming a signature of the subject from the decomposed two-dimensional array representing a motion pattern of the shape.
A method of determining a signature characteristic of a motion pattern of a shape of a body part of a subject during breathing, the method comprising:
- generating a spatial two-dimensional pattern of observational points on the body part of the subject;
- at each observational point, measuring a position of the body part in a third spatial dimension as a function of time during breathing;
- mapping the spatial and time data into a data array of at least two array-dimensions;
- decomposing the data array into modes of movement of the body part;
- and
- determining a signature characteristic of the breathing pattern of the subject from the decomposition data.
