Publication number: 20190156204Abstract: A system for training a neural network model, comprises a memory comprising instruction data representing a set of instructions and a processor configured to communicate with the memory and to execute the set of instructions. The set of instructions, when executed by the processor, cause the processor to acquire training data, the training data comprising: data, an annotation for the data as determined by a user and auxiliary data, the auxiliary data describing at least one location of interest in the data, as considered by the user when determining the annotation for the data. The set of instructions when executed by the processor, further cause the processor to train the model using the training data, by minimising an auxiliary loss function that compares the at least one location of interest to an output of one or more layers of the model and minimising a main loss function that compares the annotation for the data as determined by the user to an annotation produced by the model.Type: ApplicationFiled: November 13, 2018Publication date: May 23, 2019Inventors: Erik Bresch, Ulf Grossekathöfer

Publication number: 20190139237Abstract: A system and method are provided for enabling atlas registration in medical imaging, said atlas registration comprising matching a medical atlas 300, 302 to a medical image 320. The system and method may execute a Reinforcement Learning (RL) algorithm to learn a model for matching the medical atlas to the medical image, wherein said learning is on the basis of a reward function quantifying a degree of match between the medical atlas and the medical image. The state space of the RL algorithm may be determined on the basis of a set of features extracted from i) the atlas data and ii) the image data. As such, a model is obtained for medical atlas registration without the use, or with a reduced use, of heuristics. By using a machine learning based approach, the solution can easily be applied to different atlas matching problems, e.g., to different types of medical atlases and/or medical images.Type: ApplicationFiled: May 4, 2017Publication date: May 9, 2019Inventors: Erik Bresch, Vlado Menkovski

Patent number: 9980666Abstract: A system for determining a vital sign of a subject releases the likelihood of generating and outputting false alarms. The system includes a vital sign processor that processes the vital sign information signal measured by a sensor attached to a subject to obtain a vital sign of said subject. An image analysis unit detects motion of a marker attached to the sensor from image data obtained by an imaging unit from at least an imaging region containing the sensor. An alarm unit generates and outputs an alarm signal based (1) on the measured vital sign information signal and/or the obtained vital sign and (2) the detected motion of said marker.Type: GrantFiled: February 5, 2014Date of Patent: May 29, 2018Assignee: KONINKLIJKE PHILIPS N.
