Weight scale with ultrasound imaging for ankle displacement measurement
First Claim
1. An apparatus for correlating ankle displacement with weight, the apparatus comprising:
- a processor containing;
program code configured to calculate a weight measurement trend and an ankle displacement measurement trend,program code configured to determine a correlation factor between the weight measurement trend and the ankle displacement trend, andresponsive to the correlation factor being below a predetermined value, program code to determine whether the correlation factor being below the predetermined value is statistically significant.

Abstract
A device for correlating trend data with respect to a patient'"'"'s weight ankle displacement can identify conditions indicative of congestive heart failure. A weight scale or similar device coupled with imaging mechanism operable to measure ankle displacement collects a plurality of measurements over a period of time. Over time trend analysis of both the patient'"'"'s weight and the ankle displacement measurements can be obtained and compared to identify whether over a particular sample period an increase in a patient'"'"'s ankle displacement is or is not correlated with an increase in the patient'"'"'s weight. When an increase in ankle displacement is identified as not correlating to a corresponding change in the patient'"'"'s weight an alert can be issued of conditions indicative of congestive heart failure.
