  • Publication number: 20230240788
    Abstract: A device for processing a video stream related to a specific operative procedure. The device includes: a video stream reception interface, a processor, and a memory storing instructions, such that when the instructions are executed by the processor, they configure the device for: receiving, via the video stream reception interface, the video stream having a sequence of images including an image to be processed which represents at least a portion of an anatomical element, the image to be processed being formed by processing elements; determining, by a processing function, whether or not a criterion is satisfied in the image to be processed; determining a state of progress associated with the image to be processed based on whether or not the criterion is satisfied, the state of progress being representative of a state of progress of an operative step of the specific operative procedure.

  • Patent number: 11224386
    Abstract: A method for determining a configuration setting of a source of ionizing radiation reducing a radiation dose absorbed by a patient and a practitioner in a medical operating room during a procedure. Prior to the procedure a database of maps of simulated propagation and scattering of ionizing radiation in a model of the medical operating room is obtained for different configuration settings. During the procedure, a position of the practitioner is determined. After determining a set of configuration settings of the source enabling the production of an image of a target anatomical structure a radiation dose absorbed by the patient and the practitioner is determined using the maps from the database. A recommended configuration setting for which a combined radiation dose is reduced is then outputted.

  • Patent number: 10311178
    Abstract: A method for estimating a spatial distribution of the hazardousness of radiation doses for individuals evolving in a medical operating room defining a three-dimensional environment surrounding at least one source of radiation. First a three-dimensional model of the environment is obtained. Then a simulation of radiation doses attributable to ionizing radiation emitted from the source and scattered by the environment is computed in the model. Then, an image indicating the spatial distribution of the hazardousness for an individual of the radiation doses is generated and displayed. The three-dimensional model comprises models of individuals when the individuals are present in the environment and the image is a three-dimensional image generated for at least a portion of the model including said models of individuals.

  • Patent number: 9283675
    Abstract: A semi-automatic, interactive robotic system for performing and/or simulating a multi-step task includes a user interface system, a recognition system adapted to communicate with the user interface system, a control system adapted to communicate with the recognition system, and a sensor-actuator system adapted to communicate with the control system. The recognition system is configured to recognize actions taken by a user while the user operates the user interface system and to selectively instruct the control system to cause the sensor-actuator system to perform, and/or simulate, one of an automatic step, a semi-automatic step or direct step of the multi-step task based on the recognized actions and a task model of the multi-step task.
