ECHOGRAM DETECTION OF SKIN CONDITIONS
First Claim
Patent Images
1. A method for detecting one or more skin conditions associated with a skin of a subject, the method comprising:
- generating echogram data, comprising;
transmitting a series of acoustic pulses, wherein the series of acoustic pulses are directed at a surface of the skin, and wherein the series of acoustic pulses comprises a plurality of frequencies with at least one frequency being in the audible range;
receiving acoustic reflections corresponding to the acoustic pulses;
sampling the received acoustic reflections to generate samples; and
recording the samples as echogram data;
extracting a subwavelength acoustic reflection characteristic of the echogram data, wherein the subwavelength acoustic reflection characteristic corresponds to a reflecting feature comprising at least one dimension smaller than a corresponding acoustic pulse wavelength from the series of acoustic pulses; and
identifying the one or more skin conditions that correspond to the extracted subwavelength acoustic reflection characteristic.

Abstract
Technologies adapted for using acoustic pulses to diagnose skin conditions are disclosed. A series of acoustic pulses may be directed at a skin through the speaker of a device. Acoustic reflections may be received at a microphone. The reflections may be sampled and stored as echogram data. The echogram may be analyzed to identify potential skin conditions.
