Vacancy Postdoc on AI-driven handheld echo for cardiac applications

Job description

If a person is being diagnosed with heart failure and experiencing worsening fatigue and shortness of breath, regular monitoring of the heart’s left ventricular ejection fraction (LVEF) is essential for timely treatment adjustments. LVEF measurement is key to classifying heart failure, whether it is with reduced, preserved, or mildly reduced ejection fraction. Tailored treatment strategies, as well as some medications, are only effective for patients with reduced ejection fraction. Yet, long waiting lists for a specialist-performed ultrasound examination delays care.

A potential solution would be having an ultrasound by your general practitioner (GP) using a smartphone with an point-of-care ultrasound app. However, currently this requires an extensive training for the GP’s and a huge investment to use an ultrasound machine. In this position you will be responsible for development and clinical evaluation of an AI-driven smartphone-based app that in combination with a revolutionary handheld echo transducer will address both issues. 

Since echocardiographic imaging is complicated by finding the correct window and subsequently maneuvering the probe to the right tilt and rock to get the optimal plane, we will use a revolutionary handheld cardiac probe capable to facilitate imaging the correct plane without user intervention. For this, we will collaborate with Praesens, an organization with aim to revolutionize health care by bringing diagnostic techniques closer to the patient.

This device will facilitate the best possible image acquisition and analysis by real-time image analysis allowing a non-expert to make a diagnosis. AI-algorithms to automatically analyze the acquired ultrasound data will be developed in collaboration with Ardim to provide the Left Ventricular Ejection Fraction (LVEF), making accurate heart assessments accessible even to non-experts. Their lower cost and portability support widespread adoption in general practice and will be facilitated by the Department of Family Medicine Maastricht University. Improving diagnostic capabilities in general practice has broad societal benefits: it reduces specialist referrals, prevents hospitalizations through timely treatment, and alleviates healthcare system burdens. 

You will work on technical development of the AI algorithms and clinical validation of these algorithms in practice by:

1.  Developing AI algorithms for acquiring the correct window.
2. Developing and validating an AI based algorithm to analyze the correct images in order to provide the LVEF.
3. Testing the developed techniques.
4. Embed the developed system in an smartphone application.
5. Perform clinical evaluations of the developed system in collaboration with clinicians.

Place of work

This position is embedded in the Medical UltraSound Imaging Center (MUSIC) of the Department of Medical Imaging of the Radboud university medical center. Within MUSIC we have ample experience in developing AI driven ultrasound solutions by collaborating with the Diagnostic Image Analysis Group (DIAG). The Department of Medical Imaging is one of the leading centers in the world as also demonstrated by US News & World Report  that ranked us 3th best Medical Imaging Department in the World.

For this position you will collaborate with clinic and industry. MUSIC consists of a group of 20  researchers working on ultrasound innovations, including 5 people working on AI driven image analysis. You will be based in offices with up to max 6 people to boost interaction between scientist working on this topic. Working from home for one day per week is facilitated by full remote access to all data and archives and further boosted to online meeting possibilities. The MUSIC group has an excellent working ambiance and social culture to facilitate out-of office activities.
