PhD scholarship in A Digitalization Approach for Wall Shear Stress Estimation
3 months ago
Are you passionate about revolutionizing medical imaging with cutting-edge machine learning? Do you aspire to contribute to groundbreaking research that significantly enhances clinical workflows and patient outcomes?
The Technical University of Denmark (DTU) is seeking ambitious candidates for a PhD position focused on developing an innovative high-frame-rate ultrasound-based wall shear stress (WSS) estimation framework. This project aims to transform stroke prevention by integrating state-of-the-art machine learning techniques with advanced ultrasound imaging.
Stroke, a leading cause of death worldwide, often results from the rupture of fatty deposits called plaques in aging blood vessels, such as the carotid artery. These ruptured plaques release blood clots that travel to the brain, blocking blood vessels and causing severe brain function impairment. Wall shear stress (WSS) plays a critical role in plaque formation and rupture, influencing how blood flow interacts with vessel walls. With an aging population, Europe is projected to experience 1.5 million stroke cases annually by 2025. There is an urgent need for better tools to assess plaque development and predict rupture risk, as current methods, like MRI, are costly and cannot capture WSS dynamics. Ultrasound offers a real-time, cost-effective solution for mapping these dynamics.
This PhD project aims to develop a novel WSS estimation framework by integrating high-frame-rate ultrasound with advanced deep learning algorithms, enabling accurate measurements. The project will address key research challenges, including robust vessel wall segmentation and flow estimation using physics-informed neural networks.
What You Can Achieve by Joining DTU:
- Cutting-Edge Research Experience: Engage in pioneering research at the intersection of medical imaging and machine learning, contributing to advancements in stroke prevention and clinical workflows.
- Advanced Skill Development: Develop and refine your expertise in high-frame-rate ultrasound imaging, machine learning, and AI-based image analysis, positioning yourself at the forefront of technological innovation.
- Professional Growth: Benefit from mentorship by leading experts in the field, access state-of-the-art facilities, and participate in professional development opportunities through courses, workshops, and conferences.
By joining DTU, you will be part of a transformative journey that advances your career and contributes to significant improvements in medical science and patient care.
Responsibilities and Qualifications:
We are seeking a motivated candidate with experience in deep learning for image processing and analysis. Your main focus will be to enhance the department's expertise in ultrasound flow imaging and deep learning, contributing to the development of innovative diagnostic tools. You will collaborate with colleagues, as well as academic and industrial partners both in Denmark and internationally.
Your primary tasks will be to:
- Conduct research in the field of high-frame-rate ultrasound imaging and machine learning.
- Develop and implement machine learning models for vessel wall segmentation and WSS estimation.
- Test and refine the proposed techniques through in-vitro flow phantom studies.
- Collaborate with clinical partners at hospitals for data collection and clinical validation.
- Publish research findings in international peer-reviewed journals and present at conferences.
- Teach and supervise BSc and MSc student projects.
Key Professional Competencies Needed:
- Technical Expertise: Strong background in applied mathematics, computer science, biomedical engineering, or related fields; proficiency in image processing, computer vision, and machine learning techniques.
- Programming Skills: Advanced programming skills in languages such as Python, MATLAB, or similar, with experience in relevant deep learning packages.
- Medical Imaging Knowledge: Familiarity with medical imaging modalities, particularly ultrasound imaging; experience in high-frame-rate ultrasound imaging is highly desirable.
- Analytical Skills: Ability to analyze complex and large datasets, develop new methodologies, and validate the accuracy of the developed models.
You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.
Approval and Enrolment:
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU's rules for the PhD education.
We Offer:
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice.
