Abstract
The disclosure provides methods for diagnosis or prediction of the likelihood of a subject experiencing obstructive sleep apnea, determined at least in part by measuring the degree of tongue fat in a subject using, e.g., thermal imaging, THz imaging or other multispectral imaging.
Claims19
A method of predicting a likelihood an individual will experience or is experiencing obstructive sleep apnea, the method comprising:
- receiving multispectral image data associated with a tongue of the individual, wherein the multispectral image data comprises terahertz (THz) radiation image data;
- analyzing the multispectral image data to discern adipose tissue of the tongue of the individual from muscle, and to determine one or more parameter values associated with adipose tissue of the tongue of the individual selected from a location of adipose tissue in the tongue of the individual, a distribution of adipose tissue in the tongue of the individual, an amount of adipose tissue in the tongue of the individual or a combination thereof;
- determining, based at least in part on the determined one or more parameter values, a tongue fat score;
- and
- determining a percentage likelihood that the individual will experience or is experiencing obstructive sleep apnea (OSA) based at least in part on the determined tongue fat score.
2 more elements
A method of determining the amount or distribution of adipose tissue in the tongue of a subject, the method comprising:
- taking at least one multispectral image of the tongue, wherein the at least one multispectral image comprises a THz radiation image, thereby providing multispectral image data for the tongue;
- and
- processing the at least one multispectral image to identify adipose tissue in the tongue and discern adipose tissue of the tongue from muscle, whereby the location, amount or distribution of adipose tissue in the tongue is determined.
A system comprising
- a computer processor and a non-transitory computer-readable storage medium comprising instructions for:
- receiving multispectral image data associated with a tongue of the individual, wherein the multispectral image data comprises THz radiation image data;
- analyzing the multispectral image data to discern adipose tissue of the tongue of the individual from muscle, and to determine one or more parameter values associated with adipose tissue of the tongue of the individual selected from a location of adipose tissue in the tongue of the individual, a distribution of adipose tissue in the tongue of the individual, an amount of adipose tissue in the tongue of the individual or a combination thereof;
- determining, based at least in part on the determined one or more parameter values, a tongue fat score;
- determining a percentage likelihood that the individual will experience or is experiencing obstructive sleep apnea (OSA) based at least in part on the determined tongue fat score;
- and
- outputting the percentage likelihood to a graphical user interface.
