MeasureTime frame
Using 150 of the 170 cases of information obtained, a software system will be created to superimpose liver 3D images on laparoscopically recorded videos of the actual liver by image processing. To verify the accuracy of the software system, we will demonstrate the superimposition of liver 3D images on 20 laparoscopic liver videos and evaluate the results with a questionnaire to about 10 surgeons in our department. The questionnaire will be used to evaluate (1) accuracy, (2) practicality, and (3) time required for superimposition, each on a 5-point scale.
