Abstract: A radiological apparatus including: a gantry encapsulated within a cover, a patient platform, and two radiation sources with imaging directions orthogonal to each other, sliding vertically to perform vertical scanning of a patient standing on the platform. The gantry cover top view is L shaped, each radiation source being located outside the gantry cover, inside the angular sector of the L, and is encapsulated within a cover sliding vertically with the radiation source it encapsulates. The radiological apparatus also includes: a first security device stopping the vertical scanning, when it detects a patient body part going outside a first predetermined area, to avoid collision with the vertically sliding radiation sources covers, and a second security device stopping the vertical scanning, when it detects an object or a person external to the radiological apparatus within a second predetermined area, to avoid collision with the vertically sliding radiation sources covers.

Abstract: This invention relates to a method of radiography of an organ of a patient, comprising: first vertical scanning and said second vertical scanning being performed synchronously, wherein a computed correction is processed on both first and second raw images, on at least part of patient scanned height, for at least overweight or obese patients, so as to reduce, between first and second corrected images, cross-scattering existing between said first and second raw images, and wherein said computed correction processing on both said first and second raw images comprises: a step (32, 33, 34) of making a patient specific modeling, using as patient specific data therefore at least both first and second raw images, preferably mainly both first and second raw images, more preferably only both first and second raw images, a step (34, 35) of determining a patient specific representation of radiation scattering by said patient specific modeling, a step (36) of processing said patient specific radiation scattering representation on both said first and second raw images so as to get said first and second corrected images.

Abstract: This invention relates to a method of preoperative planning to correct spine misalignment of a patient, comprising a step of making a translation and a rotation, in a sagittal plane, of each vertebra of a set of several cervical and/or thoracic and/or lumbar imaged spine vertebrae, so that said set of imaged vertebrae presents afterwards, in the sagittal plane, the same cervical lordosis and/or the same thoracic kyphosis and/or the same lumbar lordosis as a model adapted for said patient, wherein it also comprises, before said step of making said translation and said rotation in a sagittal plane: a step of making a translation and a rotation, in a coronal plane, of each vertebra of said set of several cervical and/or thoracic and/or lumbar imaged spine vertebrae, so that said set of imaged vertebrae becomes straight in said coronal plane, and of making a rotation, in an axial plane, of each vertebra of said set of several cervical and/or thoracic and/or lumbar imaged spine vertebrae, so that said set of imaged vertebrae becomes axially aligned.

Abstract: A method for designing a patient specific orthopaedic device intended for an osteoarticular structure of a patient, based on at least two two-dimensional radiographic images of the osteoarticular structure taken respectively in two offset image-taking directions, comprising the following steps: b) locating anatomical points on the radiographic images; c) determining at least one three-dimensional geometrical feature of the patient by matching the anatomical points b) located at step b); d) determining at least one three-dimensional size parameter of the orthopaedic device based on the geometrical feature of the patient determined at step c).

Abstract: Disclosed is a medical imaging conversion method, automatically converting: at least one or more real x-ray images of a patient, including at least a first anatomical structure of the patient and a second anatomical structure of the patient, into at least one digitally reconstructed radiograph (DRR) of the patient representing the first anatomical structure without representing the second anatomical structure, by a single operation using either one convolutional neural network (CNN) or a group of convolutional neural networks (CNN) which is preliminarily trained to, both or simultaneously: differentiate the first anatomical structure from the second anatomical structure, and convert a real x-ray image into at least one digitally reconstructed radiograph (DRR).

Abstract: A spinal correction rod implant manufacturing process includes: estimating a targeted spinal correction rod implant shape based on a patient specific spine shape correction and including spine 3D modeling, one or more simulation loops each including: first simulating an intermediate spinal correction rod implant shape from modeling mechanical interaction between the patient specific spine and: either, for the first simulation, the implant shape, or, for subsequent simulation, if any, an overbent implant shape resulting from the previous simulation loop, a second simulation of an implant shape overbending applied to the targeted spinal correction rod implant shape producing an overbent spinal correction rod implant shape representing a difference between: either, for the first loop, the targeted spinal correction rod implant shape, or, for subsequent loop, if any, the overbent spinal correction rod implant shape resulting from the previous simulation loop, and the intermediate spinal correction rod implant shape.

Abstract: Disclosed is a method of radiography of an organ of a patient, including: a first vertical scanning of the organ by a first radiation source and a first detector cooperating to make a first two dimensional image of the organ, a second vertical scanning of the organ by a second radiation source and a second detector cooperating to make a second two dimensional image of the organ, the first vertical scanning and the second vertical scanning being performed synchronously, the first and second images viewing the organ of the patient according to different angles of incidence, wherein there is a vertical gap between the first source/detector and the second source/detector, such that the first vertical scanning and the second vertical scanning are performed synchronously but with a time shift in between, so as to reduce cross-scattering between the first and second images.
