简要总结
Echocardiography is the examination of choice for the study of cardiac pathologies. Interest of echocardiography for other medical specialties has already been demonstrated (intensive care in the case of hemodynamic failure - in intra and extra hospital emergency medicine for the initial assessment of chest pain or dyspnea).
The expansion of echocardiography'use has been catalyzed by miniaturization of echographic systems and decrease in their price. Recently, probes directly connected to a tablet or phone have been developed at a limited cost.
Therefore, it's possible to consider these ultrasound scanners as the new stethoscope that could be used by any health professional.
The last limit to this democratization is the training, especially for non-specialists (non-cardiologists).
详细描述
Since January 2019, echocardiography laboratory headed by Prof. Stéphane Lafitte and DESKi (start-up - Bordeaux) have been working on guiding non-experts through their cardiac ultrasound examination.
An algorithm indicating in real time if the view obtained corresponds to a reference view has already been validated. However, this algorithm does not tell the operator which movement would improve the image quality.
Thanks to advances in deep learning and by combining cardiac ultrasound acquisitions with systems that record the position of the probes in real time, it would be possible to develop an algorithm able to guide the operator's movements.
