Method for the automated and assisted acquisition of anatomical surfaces

A method for peri-operative assisted and automated acquisition of anatomical surfaces, said method comprising the steps of:

• peri-operatively manually displacing a robotized arm supporting a coordinate identifying member;
• manually identifying a plurality of noteworthy points on anatomical surfaces of a patient using the robotized arm and the coordinate identifying member, and recording coordinates of the plurality of noteworthy points and constructing a reference frame;
• creating an intermediate three-dimensional model from the reference frame;
• preliminarily bringing into correspondence the intermediate three-dimensional model with a first three-dimensional model of the anatomical surfaces acquired prior to the manually displacing step from patient medical images;
• determining a path for an automatic scanning process using the reference frame;
• automatically scanning, without manually displacing the robotized arm, a scanning zone along the path using the robotized arm;
• creating a second three-dimensional model from the automatic scanning step;
• and
• bringing into correspondence, the second three-dimensional model and the first three-dimensional model.
