Abstract: A method for measuring respiratory parameters of a subject using a range imaging sensor, wherein the method includes: receiving from the range imaging sensor at least one raw image of at least one portion of the torso of the subject, wherein each point of the raw image represents the distance between the range imaging sensor and the subject; generating a surface image of at least one portion of a surface of the torso of the subject by surface interpolation of the raw image; estimating a respiratory signal as a function of time calculated as the spatial average, in a given region of interest (ROI) defined on the torso of the subject, of the differences between the depth values of the surface image at a given time and the depth values of a reference surface image; and estimating a lung volume.

Abstract: A method for obtaining an irradiation map of a patient during interventional radiology, comprising: a learning phase consisting in submitting to a neural network a learning set comprising associations between a first input tensor comprising data of a first radiology image of a patient's intervention area, and first acquisition parameters of an interventional radiology device, and labels corresponding to an irradiation map obtained by simulation from the said first radiology image and the said first acquisition parameters, a prediction phase on a given patient, comprising the acquisition of a stream of second acquisition parameters of said interventional radiology device, the preparation of a second input tensor comprising data of a second radiology image of said given patient and of said second acquisition parameters, the submission of said second input vector to said neural network and the retrieval of an irradiation map prediction.

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.
