Ultrasound CT registration for positioning

摘要

A bone registration system is disclosed. The bone registration system may have a device including a scanner arranged to scan a target surface area of bone to obtain scan data and a first communication component. The registration system may have also a first marker positionable on a first portion of bone. The first marker may include a second communication component arranged to transmit a location signal for indicating a position of the first marker in a plurality of dimensions relative to the device. The system may have also a registration unit that compares the scan data with surface data of the bone to generate position data identifying overlapping elements of the scan data relative to the surface data, determines location data from the location signal and determines a location of the first marker on a surface of the bone using the position data and the location data.

1. A bone registration system, comprising:
a device including a scanner arranged to scan a target surface area of bone to obtain scan data and a first communication component configured to transmit a first location signal for indicating a position of the device; a first marker adapted to be positioned on a first portion of the bone, the first marker including a second communication component configured to transmit a second location signal for indicating a position of the first marker in a plurality of dimensions relative to the device; a processor configured to compare the scan data with stored surface data of the bone to generate position data identifying overlapping elements of the scan data relative to the surface data, to determine location data from the first and second location signals and to determine a location of the first marker relative to a surface of the bone in the surface data using the position data and the location data; and a second marker adapted to be positioned on a second portion of the bone, wherein the first and second markers are configured to communicate with one another to determine relative marker data including a position of the first marker relative to the second marker, wherein the processor is further configured to process the relative marker data to determine a location of the second marker relative to the surface of the bone in the surface data.
