Abstract
The subject of this invention is a system and method for distortion adaptation for use with an imaging grid alignment apparatus (analogue or digital) and method of intra-operative use for joint replacements, spine, trauma fracture reductions and deformity correction and implant placement/alignment. The system provides for real time dynamic position tracked distortion-adaption grid.
Claims11
A computer-implemented method, performed by a processor configured by a readable program code to perform the method, comprising the steps of:
- capturing an image acquired by an imaging device of a patient's anatomy;
- registering the image of the patient's anatomy to a dimensioned digital grid by selecting an at least one anatomical landmark to provide a dimensioned digital grid with at least one grid indicator;
- wherein the digital dimensioned grid is selected from the group consisting of a line, a geometrical pattern, a number, a letter and a complex pattern of multiple lines and geometries corresponding to a surgical variable configured to be superimposed on an intra-operative image anatomical image;
- providing a calibration array selected from the group consisting of a line and a shape matching an anatomical feature;
- calibrating the dimensioned digital grid to the image of a patient's anatomy to provide a calibrated dimensioned digital grid;
- deforming the calibrated dimensioned digital grid to correct for the distortion of the patient's anatomy to generate a deformed calibrated dimensioned digital grid image;
- and
- displaying the registered image with reference to the deformed calibrated dimensioned digital grid image.
A digital grid distortion calibration array based intra-operative system comprising:
- a non-transitory computer-readable storage medium encoded with computer-readable instructions which form the application software and a processor to process the instructions, wherein the application software includes:
- a data capture module configured to capture and store a digital radiographic image of a patient acquired intra-operatively by an imaging device;
- a grid registration module configured to register an anatomical image from said digital radiographic image of a patient with a digital grid and calibrate a digital representation of the digital grid to the image a patient's anatomy to provide a calibrated digital grid, said grid registration module comprising a calibration array selected from the group consisting of a line and a shape matching an anatomical feature and a digital dimensioned grid selected from the group consisting of a line, a geometrical pattern, a number, a letter and a complex pattern of multiple lines and geometries corresponding to a surgical variable configured to be superimposed on an intra-operative anatomical image, wherein the deformed digital dimensioned grid matches a quantitative warp amount within an intra operative anatomical image;
- a distortion adaptation module configured to deform the digital representation of the digital grid to correct for distortion in the anatomical image;
- and an outcome module configured to provide at least one intraoperatively instruction to a user and intraoperatively displaying the anatomical image of the patient's anatomy with reference to the deformed calibrated digital grid image.
