Problems solved by technology

[0022] However, in the absence or inattention of a physician to examine - or alternatively for staff with limited expert experience - accurate placement of monitoring equipment can be problematic
Sounds from important heart regions may be inappropriately acquired if the transducers are not positioned correctly for data collection

Abstract

An acoustic sensing apparatus and method are disclosed for acoustically surveying the chest area of a subject, and in particular the rib cage. In use the apparatus is placed on the chest, and it includes an arrangement of one or more sound sensors for sensing acoustic signals received from inside the chest. Based on the signal intensities picked up at a plurality of different locations across the chest, the different locations are each classified by a controller as either rib-aligned or intercostal space-aligned. The controller is further adapted to identify one or more sound intensity hotspots (42) within the signal intensity distribution to locate one or more anatomical objects or regions of interest within the chest, such as the heart mitral valve, the heart tricuspid valve, heart aortic valve, and the pulmonary artery as key areas for an auscultation procedure.

Description

technical field [0001] The present invention provides an acoustic sensing device and method for use in identifying one or more anatomical objects or regions of interest within a subject's chest. Background technique [0002] The article by PASCAL RAMAEKERS et al.: "Cavitation-Enhanced Back Projection for Acoustic Rib Detection and Attenuation Mapping" (ULTRASOUND IN MEDICINE ANDBIOLOGY, Vol. 41, No. 6, pp. 1726-1736 (2015)) discloses a method that allows High-intensity focused ultrasound for minimally invasive, highly localized cancer treatment for surgical procedures or chemotherapy. For high-intensity focused ultrasound interventions in the upper abdomen, the thorax blocks and distorts the ultrasound beam, causing undesired heating of healthy tissue. When using phased array therapy transducers, such complications can be minimized by applying apodization rules based on analysis of beam path obstructions. In this work, a rib detection method based on cavitation-enhanced ul...
