  • Method and system for reconstructing a 3D medical image
    Patent number: 12484862
    Abstract: The invention relates to a method for reconstructing a 3D medical image of a region of interest of a patient's body (P) lying on an operating table (200) with an X-ray imaging system comprising a motorized C-arm (100) supporting an X-ray source (101), an X-ray image detector (102) and an anti-collision device (104), comprising: —implementing a first path of the motorized C-arm without acquiring any X-ray image, said first path comprising at least two different angular positions around a rotation axis of the C-arm; —at each angular position of the C-arm along said first path, detecting with the anti-collision device (104) an external surface (S) of the patient's body and recording volumetric data of a patient's body portion enclosing the region of interest; —computing a volumetric model of the patient's body portion based on said volumetric data and on an estimation of X-ray absorption of patient's body tissues surrounding the region of interest, said volumetric model comprising a first part including the regi
