Title

(EN) SYSTEMS, DEVICES, AND METHODS FOR COMPUTER-AIDED AUSCULTATION

(FR) SYSTÈMES, DISPOSITIFS ET PROCÉDÉS D'AUSCULTATION ASSISTÉE PAR ORDINATEUR

Abstract

(EN) A system for diagnosing a health condition of a patient, a diagnostic device for diagnosing a health condition of a patient, and a method of diagnosing a health condition of a patient, are disclosed. A computer-implemented method of diagnosing a health condition of a patient comprises: receiving an acoustic signal obtained from a diagnostic device measuring an internal parameter of the patient; inputting a frequency domain representation of the acoustic signal into a machine learning model trained to determine a presence of the health condition in the patient based on the acoustic signal; and generating an output for display on a user device based on a result from the machine learning model. A diagnostic device comprises a signal acquisition module configured to acquire an acoustic signal based on structure-borne vibration from a patient, and a controller coupled to the signal acquisition module.

(FR) L'invention concerne un système de diagnostic d'un état de santé d'un patient, un dispositif de diagnostic pour diagnostiquer un état de santé d'un patient, et un procédé de diagnostic d'un état de santé d'un patient. Un procédé mis en œuvre par ordinateur de diagnostic d'un état de santé d'un patient consiste à : recevoir un signal acoustique obtenu à partir d'un dispositif de diagnostic mesurant un paramètre interne du patient ; entrer une représentation de domaine fréquentiel du signal acoustique dans un modèle d'apprentissage automatique entraîné pour déterminer une présence de l'état de santé chez le patient sur la base du signal acoustique ; et générer une sortie pour un affichage sur un dispositif utilisateur sur la base d'un résultat provenant du modèle d'apprentissage automatique. Un dispositif de diagnostic comprend un module d'acquisition de signal configuré pour acquérir un signal acoustique sur la base d'une vibration portée par une structure provenant d'un patient, et un dispositif de commande couplé au module d'acquisition de signal.
