A key-pose is determined as an approximate position and orientation of a medical instrument with respect to the patient's organ. Based on the key-pose, an overlay is generated on a 2D image of the patient's organ, acquired by the medical instrument, by projecting the 3D virtual model on to the 2D image. A pair of feature points includes a 2D feature point from the 2D image and a corresponding 3D feature point from the 3D virtual model. The 3D coordinate of the 3D feature point is determined based on the 2D coordinate of the 2D feature point. The depth of the 3D coordinate is on a line of sight of the 2D feature point and is determined so that the projection of the 3D virtual model from the depth creates an overlay approximately matching the organ observed in the 2D image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system of model fusion for laparoscopic surgical guidance","description":"The present teaching relates to method, system, medium, and implementations for fusing a 3D virtual model with a 2D image associated with an organ of a patient.
