ORTHOPEDIC FIXATION WITH IMAGERY ANALYSIS Russian patent published in 2016 - IPC A61B17/62 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to devices for analysis of images during dental fixation. Computer-readable data medium has computer-readable instructions which, when executed by one or more processors, execute method of orthopaedic fixation images analysing, which contains capture one or more image generators, first and second 2D images of fixation device and first and second segments of bone, attached to it, first image is captured from first orientation, and second image captured from second orientation, different from first orientation , obtaining plurality of parameters of scene image formation based on comparison of identified corresponding location of multiple elements of retainer in first and second two-dimensional images with appropriate locations multiple elements of retainer in three-dimensional space, at retainer contain components of fixation device. Obtaining plurality of parameters of scene images generation comprises identification of appropriate location of multiple elements of retainer in first and second two-dimensional images, first and second transformation matrices corresponding to first and second two-dimensional images using identified corresponding location of multiple elements of retainer, and decomposition of transformation matrices into plurality of parameters of scene images generation. After that, restoring 3D representation of first and second segments bone relative to fixation device is performed on basis of plurality of parameters of image forming scene. In second version of computer-readable data medium processors method is executed comprising preliminary production of first and second 2D images of fixation device and first and second segments of bone, attached to it, first image is captured from orientation, and second image is captured of second orientation, different from first orientation, set of parameters of scene image formation based on comparison of identified corresponding location of multiple elements of retainer in first and second two-dimensional images with appropriate locations multiple elements of retainer in three-dimensional space. At that multiple elements of retainer contain components of fixation device. At that, multiple parameters of scene images generation comprises identification of appropriate location of multiple elements of retainer in first and second two-dimensional images, first and second transformation matrices and decomposition of transformation matrices on parameters of scene image forming apparatus, and recovery of 3D representation of first and second segments bone relative to fixation device on basis of plurality of parameters of image forming scene.

EFFECT: using invention allows to expanded range of technical means of image analysis in orthopaedic fixation.
