Abstract

Disclosed is a system to assist in a procedure. During the procedure an object may be moved relative to a subject, such as being positioned and/or placed within a subject. The system and related method may be used to assist in displaying and/or determining a pose of the object relative to a subject, such as rigid portions of a subject.

First claim

What is claimed is:

1 . A method of planning an implant configuration for a procedure, comprising:
accessing an image data of a subject having at least a first portion and a second portion of the subject; analyzing a region of interest (ROI) between the first portion and the second portion; determining an ROI volume geometry of the region of interest between the first portion and the second portion of the subject;
accessing a model of an object, the model including at least (i) a dimension of a rigid portion of the object and (ii) a plurality of possible configurations of a configurable portion of the object;
analyzing the accessed model to determine whether the object may achieve the ROI volume geometry; and
outputting a result of the analysis of the accessed model;
wherein outputting the result includes determining if the object fills a selected threshold of the determined ROI volume geometry but not greater than the determined ROI volume geometry.

2 . The method of claim 1 , further comprising:
selecting the region of interest in the image data with an input from a user.

3 . The method of claim 1 , wherein the plurality of possible configurations of the configurable portion of the object includes at least one of a range of motion of the configurable portion, a plastic deformation range of the configurable portion, an elastic deformation range of the configurable portion, or combinations thereof.

4 . The method of claim 1 , wherein outputting the result includes outputting that the object may positively achieve the ROI volume geometry within the selected threshold or outputting that the object may not achieve the ROI volume geometry within the selected threshold.

5 . The method of claim 4 , further comprising:
evaluating for the implant the object based on the output result of the analysis of the accessed first model.

6 . The method of claim 1 , wherein the model of the object is a first model of a first object, the method further comprising:
accessing a second model of a second object, wherein the second model of the second object includes at least (i) a dimension of a rigid portion of the second object and (ii) a plurality of possible configurations of a configurable portion of the second object; analyzing the accessed second model to determine whether the second object may achieve the ROI volume geometry based on the accessed second model; and outputting a result of the analysis of the accessed second model.

7 . The method of claim 6 , further comprising:
comparing the output result of the analysis of the accessed first model and the output result of the analysis of the accessed second model; and outputting a comparison result of the comparing the output result of the analysis of the accessed first model and the output result of the analysis of the accessed second model.

8 . The method of claim 7 , further comprising:
determining an optimal fit of the first object or the second object to the ROI volume geometry based on the comparing the output result of the analysis of the accessed first model and the output result of the analysis of the accessed second model.

9 . The method of claim 1 , wherein the model is a first model and the object is a first object, the method further comprising:
determining whether the output result of the analysis of the accessed first model matches the ROI volume geometry within the selected threshold; if the output result of the analysis of the accessed first model is outside the selected threshold match of the ROI volume geometry: accessing a second model of a second object, wherein the second model of the second object includes at least (i) a dimension of a rigid portion of the second object and (ii) a plurality of possible configurations of a configurable portion of the second object; analyzing the accessed second model to determine whether the second object may achieve the ROI volume geometry based on the accessed second model; and outputting a result of the analysis of the accessed second model.

10 . A system for planning an implant configuration for a procedure, comprising:
a processor system configured to execute instructions to: access an image data of a subject having at least a first portion and a second portion of the subject; analyze a region of interest (ROI) between the first portion and the second portion; analyze an ROI volume geometry of the region of interest between the first portion and the second portion of the subject; access a model of an object, the model including at least (i) a dimension of a rigid portion of the object and (ii) a plurality of possible configurations of a configurable portion of the first object; analyze the accessed model to determine whether the object may achieve the ROI volume geometry; and output a result of the analysis of the accessed first model; and an output device to receive the output; wherein outputting the result includes determining if the object fills a selected threshold of the determined ROI volume geometry but not greater than the determined ROI volume geometry.

11 . The system of claim 10 , further comprising:
a user input device to input a selection of the region of interest in the image data with an input from a user.

12 . The system of claim 10 , wherein the output device is operable to display whether the object is able to achieve the ROI volume geometry within the selected threshold.

13 . The system of claim 10 , wherein the model of the object is a first model of a first object, and wherein the processor system is configured to execute further instructions to:
access a second model of a second object, wherein the second model of the second object includes at least (i) a dimension of a rigid portion of the second object and (ii) a plurality of possible configurations of a configurable portion of the second object; analyze the accessed second model to determine whether the second object may achieve the ROI volume geometry based on the accessed second model; and output a result of the analysis of the accessed second model.

14 . The system of claim 13 , wherein the processor system is configured to execute further instructions to:
compare the output result of the analysis of the accessed first model and the output result of the analysis of the accessed second model; and output a comparison result of the comparing the output result of the analysis of the accessed first model and the output result of the analysis of the accessed second model.

15 . The system of claim 14 , wherein the processor system is configured to execute further instructions to:
determine an optimal fit of the first object or the second object to the ROI volume geometry based on the comparing the output result of the analysis of the accessed first model and the output result of the analysis of the accessed second model.

16 . The system of claim 10 , wherein the model of the object is a first model of a first object, and wherein the processor system is configured to execute further instructions to:
determine whether the output result of the analysis of the accessed first model matches the ROI volume geometry within the selected threshold; if the output result of the analysis of the accessed first model is outside the selected threshold match of the ROI volume geometry: access a second model of a second object, wherein the second model of the second object includes at least (i) a dimension of a rigid portion of the second object and (ii) a plurality of possible configurations of a configurable portion of the second object; analyze the a
