Abstract
Described herein are methods, systems and devices for image-guided, computer-assisted surgical procedures, in particular for intra-operative registration of anatomical structures. Embodiments of the invention may enable a user to register the surface of an anatomical structure intra-operatively in an interactive, computer-guided process. The user may send information about acquired data points to the computer, and the computer may evaluate the aggregate of data points, optionally provide instructions to the user for acquisition of additional data points, and signal to the user when sufficient data points have been acquired for registration of the surface of the anatomical structure.
Claims20
A computer-assisted method of registering a surface of an anatomical structure, the method comprising:
- acquiring data points on the surface;
- evaluating quality of acquired data points;
- optionally rejecting unacceptable data points;
- collecting acceptable data points;
- evaluating quantity of acceptable data points;
- assessing if sufficient data points have been collected to achieve convergence of registration of the surface with a previously generated representation of the anatomical structure;
- optionally generating instructions for additional data points to be acquired;
- and
- optionally continuing acquiring data points at least until sufficient acceptable data points have been collected to achieve convergence of registration of the surface with a previously generated representation of the anatomical structure.
A computer-assisted method of registering a surface of an anatomical structure, the method comprising:
- acquiring data points on the surface;
- and
- employing a computer to:
- evaluate quality of acquired data points;
- optionally reject data points of insufficient quality;
- collect data points of sufficient quality;
- evaluate quantity of collected data points;
- and
- assess if sufficient data points have been collected to achieve convergence of registration of the surface with a previously generated representation of the anatomical structure;
A computerized system, comprising:
- A computer having a CPU, the CPU being capable of running a computer algorithm capable of:
- receiving information about acquired data points from a surface of an anatomical structure;
- evaluating quality of the data points;
- optionally rejection data points of insufficient quality;
- collecting data points of sufficient quality;
- evaluating quantity of collected data points for sufficiency for registration of the anatomical surface;
- optionally generating user instructions for acquisition of additional data point;
- and
- generating a signal for stopping acquisition of data points once sufficient data points have been collected;
- an acquisition probe capable of acquiring data points on the surface of the anatomical structure;
- a detector capable of detecting the position of the acquisition probe, and
- a user interface.
An acquisition probe having a detection mechanism for detecting a data point on a surface of an anatomical structure, the acquisition probe being capable of automatically triggering acquisition of the data point by a computer, based on the position of the acquisition probe on the surface of the anatomical structure.
