Claim Text:
1. A system for diagnosing otitis media using terahertz electromagnetic waves comprising: a terahertz probe which includes a generating unit for radiating terahertz electromagnetic waves from the outside of an ear toward a tympanic cavity and a detection unit for detecting the reflected terahertz electromagnetic waves reflected from the tympanic cavity; a converting unit which converts the reflected terahertz electromagnetic waves detected by the detection unit into an electrical signal and sends the electrical signal to a control unit; and a control unit which performs otitis media diagnosis using the electrical signal sent from the converting unit; wherein the control unit diagnoses otitis media by discriminating occurrence, progression, and kinds of otitis media using at least one of strength and phase of the electric signal; and wherein the control unit diagnoses otitis media at the early stage by analyzing strength of the electric signal in the normal eardrum and strength of the electric signal in a patient's eardrum where the strength of the electric signal is gradually reduced when otitis media occurs, diagnoses the state and the degree of risk of otitis media by analyzing how much strength of the electric signal is reduced as time goes by, diagnoses progressive otitis media and chronic otitis media using the strength of the electric signal and the point at which the peak value of the electric signal is detected, diagnoses exudative otitis media by analyzing the strength of the electric signal, and diagnoses acute otitis media and chronic otitis media by analyzing the state of the eardrum using strength and phase of the electric signal.
