  • MATLAB Seminar March 16 3-4PM: Medical Image Analysis and AI Workflows

    Medical images come from multiple sources such as MRI, CT, X-ray, ultrasound, and PET. Analysis of these images requires a comprehensive environment for data access, visualization, processing, and algorithm development. The main challenge is to extract clinically meaningful information based on advanced techniques such as Artificial Intelligence (AI). To achieve this, one needs to clean, segment, register, and label a large collection of images. For the AI analysis, there are many more challenges such as iteratively adjusting AI models or learning parameters. MATLAB provides tools such as Medical Imaging Toolbox and Deep Learning Toolbox and algorithms for end-to-end medical image analysis and AI workflow.

  • What is Research Computing?

    UVA Research Computing (RC) is a new program that aims to support computational biomedical research by providing advanced cyberinfrastructure and expertise in data analysis at scale. Our mission is to foster a culture of computational thinking and promote interdisciplinary collaboration in various data-driven research domains. We offer services related to high performance computing, cloud architecture, scientific programming and big data solutions. We also aim to promote computationally intensive research at UVA through collaborative efforts such as UVA’s own CADRE (Computation And Data Resource Exchange) and XSEDE (Extreme Science and Engineering Discovery Environment).
    One of our driving philosophies is that researchers already have medical and scientific expertise, and should not have to become computing experts on top of that.
