Abstract

A method, apparatus and computer program code for automatically planning at least a part of a surgical procedure to be carried out on a body part of a patient are described. A virtual model of the body part is provided, in which the model has data associated with it representing at least a part of a planned surgical procedure. The virtual model is then morphed to the body part using data derived from the patient'"'"'s real body part thereby also adapting the part of the planned surgical procedure to reflect the anatomy of the patient'"'"'s real body part.

Claims

1. A computer implemented method of automatically planning at least a part of a surgical procedure to be carried out on a body part of a patient, comprising:

providing a virtual model of the body part, the model having data associated with it representing at least a part of a planned surgical procedure to be carried out on a corresponding real body part of the patient; and

morphing the virtual model of the body part using data derived from the patient'"'"'s real body part to thereby adapt the part of the planned surgical procedure to reflect the anatomy of the patient'"'"'s real body part.

2. The method of claim 1, wherein the virtual model is based on at least one of X-ray, CT, electromagnetic and ultrasound scan data.

3. The method of claim 1, in which the morphing step comprises identifying the closest scan data from a data library to anatomical data from the patient.

4. The method of claim 1, further comprising the step of incorporating in the virtual model a representation of a component of hardware that is to be used in the procedure.

5. The method of claim 4, wherein the component of hardware comprises a surgical instrument.

6. The method of claim 4, wherein the component of hardware comprises an implant.

7. The method of claim 4, wherein the position and orientation of the component of hardware is represented by data in at least five degrees of freedom.

8. An apparatus for automatically planning at least a part of a surgical procedure to be carried out on a body part of a patient, comprising a data processing device and a memory storing computer program instructions that can configure the date processing device to:

provide a virtual model of the body part, the model having data associated therewith representing at least a part of a planned surgical procedure to be carried out on a corresponding real body part of the patient; and

morph the virtual model of the body part using data derived from the patient'"'"'s real body part thereby also adapting the part of the planned surgical procedure to reflect the anatomy of the patient'"'"'s real body part.

9. A method for creating a statistical shape model incorporating surgical planning information for a body part, comprising:

generating anatomical data representing the anatomical shape of the body part from images of a plurality of training subjects;

generating planning data that can be used to describe at least one planning property for a surgical procedure from images of the plurality of training subjects; and

creating a statistical shape model from the anatomical data and planning data.

10. A method of instantiating a statistical shape model and automatically generating surgical planning information, comprising:

creating a statistical shape model according to the method of claim 10; and

instantiating a model of an actual patient using information derived from the actual anatomy of the patient, whereby instantiating the model generates surgical planning data that directly or indirectly provides surgical planning information adapted for the patient'"'"'s actual anatomy.

11. An apparatus for automatically planning at least a part of a surgical procedure to be carried out on a body part of a patient, comprising a data processing device and a memory storing computer program instructions which can configure the date processing device to:

instantiate a model of an actual patient from a statistical shape model incorporating surgical planning information for the body part using information derived from the actual anatomy of the patient; and

generate surgical planning information adapted for the patient'"'"'s actual anatomy from the instantiated model.
