3 results about "Blood circulation disorder" patented technology

This invention relates to the field of medical data mining technology, specifically to a system for assessing eye muscle fatigue in myasthenia gravis based on infrared thermal imaging. First, the degree of blood circulation impairment is determined based on the temperature changes of pixels in various directions within a speckled region. Then, based on the number of speckled regions and the concentration of hot spots, a speckled region influence value reflecting local blood circulation and metabolic abnormalities is determined. Next, combining the degree of blood circulation impairment, the speckled region influence value, and the speckled region distribution, a comprehensive reference degree of eye muscle fatigue is determined. Furthermore, considering the distribution of speckled regions under the influence of grease, the degree of blood circulation impairment, and the characteristic that the reference degree of eye muscle fatigue typically does not change, a corresponding grease influence value is determined. Thus, combining the reference degree of eye muscle fatigue and the grease influence value allows for a more accurate determination of the eye muscle fatigue assessment value, resulting in better assessment of eye muscle fatigue in myasthenia gravis based on this value.
