Abstract
A new generation of precision medicine with interfaces processing the predictive feedback over the course of hyperthermia treatment sessions is provided. Implementation of MR-thermometry measurements and real-time spatial imaging can resolve many of the limiting factors currently associated with hyperthermia treatment. More significantly, implementation of artificial intelligence (machine learning) mediated image analysis and database construction can provide the international community with standards for monitoring, and thermal dose calibration.
Claims14
A system for performing MRI-guided hyperthermia treatment, comprising:
- a magnetic resonance imaging (MRI) unit, configured to acquire MRI images from an imaging zone before, during and after a hyperthermia treatment, wherein the imaging zone includes a region of treatment (ROT) that are indicated by a contrast agent using hepatitis e nanoparticles (HEVNP);
- a backend platform, comprising:
- a graphic processing unit (GPU), configured to receive and process the MRI images from the MRI unit and sensory data, and detect features of the ROT for the MRI images;
- a computing unit, configured to implement machine learning-aided analysis, wherein the machine learning-aided analysis extracts information from the features of the ROT and the sensory data to train a predictive model, and the predictive model generates, based on the MRI images and the sensory data, consecutive real-time visualization images of the ROT and thermal dose calibration during the hyperthermia treatment;
- and
- a database, configured to store the MRI images, the sensory data, the real-time visualization images and the thermal dose calibration;
- and
- a frontend platform, configured to display the consecutive real-time visualization images and the thermal dose calibration to an operator, and allow the operator to operate the MRI-guided hyperthermia treatment, the frontend platform comprising:
- a graphic user interface (GUI), configured to display the consecutive real-time visualization images and the thermal dose calibration;
- and
- a controller, configured to receive a value of thermal dose inputted by the operator during the hyperthermia treatment, and send the value of thermal dose to a treatment unit to control heating during the hyperthermia treatment, wherein the sensory data is selected from the group consisting of regional temperature, thermal dose and biological effect;
- wherein the features of the ROT includes textural components and size of the ROT;
- wherein the GPU comprises a high-throughput image processing GPU (HTIP-GPU), the processing of the MRI images and sensory data is performed by the HTIP-GPU;
