Deformed grid based intra-operative system and method of use

1. 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.

2. The method of claim 1 wherein the step of calibrating the dimensioned digital grid comprises calculating the location of the calibration array relative to the anatomy of the patient and quantifying the amount of distortion in the image.

3. The method of claim 1 wherein a deformation field is computed from the at least one anatomical landmark using a thin-plate spline.

4. The method of claim 3 wherein the step of registering the intra-operative image further comprises: aligning the at least one anatomical landmark of the dimensioned digital grid with an at least one anatomical landmark in a distortion calibration array image using an affine transformation and the deformation field.

5. The method of claim 1 further comprising the steps of

if the surgeon elects to adjust a patient or an equipment,

selecting a point on the anatomy of the patient to direct the placement of the dimensioned digital grid.

6. 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.

7. The system of claim 6 further comprising: an auto-segmentation module configured to automatically select for a successive anatomical image for an at least one anatomical landmark.

8. The system of claim 6 wherein said outcome module comprises a digital grid selected from the group consisting of: mixed, augmented reality, and holographic grid.

9. The system of claim 6 wherein said data capture module is configured to obtain data from a sensor.

10. The system of claim 9 wherein said sensor is in electronic communication with a grid selected from the group consisting of: a mixed reality, an augmented reality, and a holographic grid.

11. The system of claim 9 wherein said outcome module comprises a display selected from the group consisting of: a mixed reality display, an augmented reality display and a holographic display.
