Title:
TECHNOLOGY FOR DETERMINING SPATIAL ORIENTATION OF INPUT IMAGES FOR USE IN ORTHOPEDIC SURGICAL PROCEDURE
Document Type and Number:
Japanese Patent JP2021053372
Kind Code:
A
Abstract:
To provide a technology for determining the spatial orientation of input images to produce a three-dimensional model.SOLUTION: The technology includes a device having circuitry to obtain two-dimensional images of an anatomical object (e.g., a bone of a human joint), to determine candidate values indicative of translation and rotation of the anatomical object in the two-dimensional images, and to produce, as a function of the obtained two-dimensional images and the candidate values, a candidate three-dimensional model of the anatomical object. The circuitry is also to determine a score indicative of an accuracy of the candidate three-dimensional model, to determine whether the score satisfies a threshold, and to produce, in response to a determination that the score satisfies the threshold, data indicating that the candidate three-dimensional model is an accurate representation of the anatomical object.SELECTED DRAWING: Figure 1
