Summary
A group of Vanderbilt University researchers have developed a solution that will correct for the mis-registration of image data in image-guided surgery. The solution uses software to correct for any mis-registration that is caused by the presence of intraoperative deformations. This invention helps to improve the performance and capabilities of image-guided surgery.
Technology Description
Prior to the operation, a pre-operative image of the organ of surgical/interventional interest is acquired. Prior to surgery a computational model of the organ of interest is generated. During the surgery, the physical organ is presented for surgery/intervention which can often experiences deformation or shape change when compared to its pre-operative state. The shape change can be digitized by the image-guided system. Using the digitized data and the computer model based on pre-operative images, a nonrigid alignment relationship is established among pre-operative model, corresponding image data, and intraoperative organ presentation. This process allows for the physician to better use pre-operative information and to localize tissue for the performance of surgery/intervention.
Unique Properties and Applications
- This technology would be the first commercially available image-guided system that accounts for deformation during surgery.
- This approach can be tailored to individual organs.
- This approach can be used to improve the accuracy of tool use for surgery and intervention.
Technology Development Status
Technology has been fully developed, tested and validated in clinical practice.
