Claims9
A body scanning device comprising:
- a sensor module comprising multiple microphones attached to multiple sites separated from each other on a patient body to collect an internal body sound from the patient body;
- a data processing unit converting audio signals collected by the multiple microphones into digital signals and obtaining frequency information of the audio signals through fast Fourier transform;
- and
- an analysis unit classifying the internal body sound generated from the patient body among multiple audio signals generated from the multiple microphones based on the frequency information provided by the data processing unit and recognizing that a location of a microphone detecting the internal body sound is a location at which the internal body sound is generated,
- wherein the analysis unit learns frequency characteristics of a sound generated from the patient internal organs in a preset state through artificial intelligence to detect an audio signal having the frequency characteristics among audio signals classified as the internal body sound,
- wherein the multiple microphones are arranged at constant intervals in a two-dimensional matrix, and
- wherein marking lamps are attached to the multiple microphones, the marking lamp that detects the internal body sound being turned on.
A body scanning method of a body scanning device comprising:
- attaching multiple microphones to a scanning target region on a patient body to be separated from each other on the patient body, followed by collecting internal body sounds of the patient body;
- converting, by a data processing unit, audio signals collected by the multiple microphones into digital signals to obtain frequency information of the audio signals through fast Fourier transform of the audio signals;
- and
- classifying, by an analysis unit, an internal body sound among the audio signals generated from the multiple microphones using the frequency information to recognize that a location of a microphone detecting the internal body sound is a location at which the internal body sound is generated,
- wherein classifying the internal body sound comprises learning frequency characteristics of a sound generated from the patient internal organs in a preset state through an artificial intelligence algorithm and detecting an audio signal having the frequency characteristics among audio signals classified as the internal body sound by the artificial intelligence algorithm,
- wherein the multiple microphones are arranged at constant intervals in a two-dimensional matrix,
- wherein marking lamps are attached to the multiple microphones, the marking lamp that detects the internal body sound being turned on.
