  • Publication number: 20250140382
    Abstract: Systems and methods for performing a medical imaging analysis task using a machine learning based model (e.g., a foundational model) are provided. One or more input medical images are received. One or more modality-specific expert subnetworks of the machine learning based model are selected for performing a first processing of the one or more input medical images. The first processing of the one or more input medical images is performed for performing a medical imaging analysis task using the one or more selected modality-specific expert subnetworks. Results of the first processing are merged into one or more sets of merged results. One or more cross-modality expert subnetworks of the machine learning based model are selected for performing a second processing of the one or more sets of merged results. The second processing of the one or more sets of merged results is performed for performing the medical imaging analysis task using the one or more selected cross-modality expert subnetworks.

  • Publication number: 20250111656
    Abstract: Systems and methods for performing a medical analysis task using a trained machine learning based task network are provided. Input medical data is received. A medical analysis task is performed using a trained machine learning based task network based on the input medical data. Results of the medical analysis task are output. The trained machine learning based task network is trained by: receiving unannotated training medical data; generating weakly-supervised labels for the unannotated training medical data using one or more trained machine learning based supervised learning networks; training the machine learning based task network for performing the medical analysis task based on 1) the unannotated training medical data, 2) self-supervised labels for the unannotated training medical data learned via self-supervised learning, and 3) the generated weakly-supervised labels for the unannotated training medical data; and outputting the trained machine learning based task network.

  • Publication number: 20250054603
    Abstract: Systems and methods for performing one or more medical imaging analysis tasks are provided. A sequence of medical images is received. One or more patches are extracted from each image of the sequence of medical images. Spatio-temporal features are extracted from the one or more extracted patches using a machine learning based encoder network. One or more medical imaging analysis tasks are performed based on the extracted spatio-temporal features. Results of the one or more medical imaging analysis tasks are output. The machine learning based encoder network is trained by receiving a sequence of training medical images. Patches of a first set of images of the sequence of training medical images are masked according to a first masking strategy. Patches of a second set of images of the sequence of training medical images are masked according to a second masking strategy.

  • Publication number: 20240099784
    Abstract: A tip of a vascular catheter is detected in a sequence of vessel image frames obtained using x-rays. Within the vessel image frames, a proximal point corresponding to a vessel ostium is determined. The sequence of vessel image frames are cropped to an image area surrounding the proximal point to generate a cropped sequence of cropped vessel image frames. Within cropped vessel image frames not indicative of a contrast medium, the tip of the vascular catheter is detected, and the detected tip of the vascular catheter is tracked.
