Problems solved by technology

Although much of the following discussion uses surgical procedures in the brain as an example, similar problems arise in surgery on the spine and other orthopedic applications and the techniques are generally applicable
[0008] The complexities associated with tissue displacement that occurs during surgery are not well addressed by currently available systems and methods

[0119] Example: Medical Procedures Involving the Brain

[0120] Figure 6 A flowchart illustrating the present method of modeling fiber bundle deformation comprising a DTI image and a surgical tool shape model. Figure 6 is an implementation for the specific case of only generating a fiber bundle deformation model and does not involve Figure 5 other tissue types as described in . exist Figure 6 , two data streams (comprising DTI image data (step 302) and tool shape model (step 310)) are received as input data.

[0121] After receiving the DTI image set data (step 302), the system then preprocesses the data (step 304), typically using streamline tractography algorithms. After preprocessing (step 304), a fiber bundle map is created (step 306). A tissue model is then generated (step 308) using the fiber tract map generated in step 306.

Abstract

Disclosed herein is a method for producing an evolvable tissue model of a patient and, using this model, modelling physical transformations of the tissue (e.g. deformation) of the tissue model by interacting the tissue model with influence models which model interactions with the tissue such as surgical instruments, pressure, swelling, temperature changes etc. The model is produced from a set of input data of the tissue which includes directional information of the tissue. The directional information is used to produce an oriented tissue map. A tissue model is then produced from the oriented tissue map such that the tissue model reflects the directionality of the tissue component. When the tissue model is subjected to an influence that causes tissue deformation over a period of time, the tissue model directionally deforms over the period of time in a manner which reflects a trajectory of the influence interacting with the directionality of the tissue component.
