Abstract: A device for categorising regions in images is disclosed. The device comprising: an input for receiving a first set of images, and defining one or more regions of for each image of the first set of images and a categorisation for the one or more regions, and a second set of images, and a categorisation for each image of the second set; and a processor configured to train a first machine learning algorithm to categorise features in images by: processing the images of the first and second set using the first algorithm to estimate feature regions in the images and a categorisation for each of the feature regions, and training the first algorithm in dependence on the categorisations received for the images of the first and second sets.

Abstract: A computer-implemented system is provided that receives a real-time video captured from a medical image device during a medical procedure. The real-time video may include a plurality of frames. The system may be adapted to detect an object of interest in the plurality of frames and apply one or more neural networks configured to identify a plurality of characteristics of the detected object of interest, such as classification, size, and/or location. In some embodiments, the system is adapted to identify, based on one or more of the plurality of characteristics, a medical guideline and present, in real-time on a display device during the medical procedure, information for the medical guideline.

Abstract: A computer-implemented method for detecting at least one feature of interest in images captured with an imaging device includes: receiving an ordered set of images and analyzing one or more subsets of the ordered set using a local spatio-temporal processing module. The local spatio-temporal processing module determines presence of characteristics related to the feature of interest in each image of each subset of images and annotates the subset of images. The method also includes processing a set of feature vectors of the ordered set of images using a global spatio-temporal processing module to refine the determined characteristics associated with each subset of images, and calculate one or more values for each image using a timeseries analysis module, the values being representative of the feature of interest and calculated using the refined characteristics associated with each subset of images and spatio-temporal information.

Abstract: A method (1) is described for training a machine learning model (2) to receive as input a time-resolved three-dimensional model (4) of a heart or a portion of a heart, and to output (3) a predicted time-to-event or a measure of risk for an adverse cardiac event. The method includes receiving a training set (5). The training set (5) includes a number of time-resolved three-dimensional models (41, . . . , 4N) of a heart or a portion of a heart. The training set (5) also includes, for each time-resolved three-dimensional model (41, . . . , 4N), corresponding outcome data (71, . . . , 7N) associated with the time-resolved three-dimensional model (41, . . . , 4N). The method (1) of training a machine learning model (2) also includes, using the training set (5) as input, training the machine learning model (2) to recognise latent representations (12) of cardiac motion which are predictive of an adverse cardiac event.
