METHODS AND APPARATUSES FOR GRAPHIC PROCESSING IN A VISUAL DISPLAY SYSTEM FOR THE PLANNING AND EXECUTION OF FUSION OF THE CERVICAL SPINE
Disclosed are methods, apparatuses and software products for graphic processing using a visual display system and image analysis for sizing of surgical implants in the planning and execution of spinal surgery, such as spinal fusion surgery of the cervical spine. The graphic processing includes determining a trajectory line for one or more target spine levels captured and measured by one or more measuring system to generate a 3D motion dataset for use in a range of diagnostic and therapeutic applications.

extract parameter information of at least one of the first vertebral body and the second vertebral body from the target spine level of the input image;
derive a vertebral body motion from at least one of the first vertebral body and the second vertebral body of the input image of the target spine level;
determine a trajectory line for a motion of at least one of the first vertebral body and the second vertebral body of the target spine level; and
analyze the vertebral body motion and the trajectory line to determine a range of size parameters for surgical implant devices.
2 . The image processing apparatus of claim 1 comprising one or more processors to provide size parameter for surgical implant devices to at least one of a surgical planning system and an intra-operative system.
3 . The image processing apparatus of claim 1 comprising one or more processors wherein the parameter information is a box drawn from a four point markup of at least one of the first vertebral body and the second vertebral body.
4 . The image processing apparatus of claim 1 comprising one or more processors wherein a first trajectory line extends from a first corner point of a selected vertebral body of the at least one of the first vertebral body and the second vertebral body.
5 . The image processing apparatus of claim 4 comprising one or more processors wherein a second trajectory line extends from a second corner point of the selected vertebral body.
6 . The image processing apparatus of claim 1 comprising one or more processors wherein the parameter information is an outline of a first spinous process and a second spinous process.
7 . The image processing apparatus of claim 6 comprising one or more processors to determine an extension parameter information which corresponds to the first spinous process touching the second spinous process.
8 . A method of processing an image for use by an image processing apparatus having one or more processors, the method comprising:
selecting an input image of a target spine level having at least a first vertebral body and a second vertebral body;
extracting parameter information of at least one of the first vertebral body and the second vertebral body from the target spine level of the input image;
deriving a vertebral body motion from at least one of the first vertebral body and the second vertebral body of the input target spine level of the input image;
determining a trajectory line for a motion of at least one of the first vertebral body and the second vertebral body of the target spine level; and
analyzing the vertebral body motion and trajectory line to determine a range of size parameters for surgical implant devices.
9 . The method of processing of claim 8 comprising providing size parameter for surgical implant devices to at least one of a surgical planning system an an intra-operative system.
10 . The method of processing of claim 8 wherein the parameter information is a box drawn from a four point markup of at least one of the first vertebral body and the second vertebral body.
11 . The method of processing of claim 8 wherein a first trajectory line extends from a first corner point of a selected vertebral body of the least one of the first vertebral body and the second vertebral body.
12 . The method of processing of claim 11 wherein a second trajectory line extends from a second corner point of the selected vertebral body.
13 . The method of processing of claim 8 wherein the parameter information is an outline of a first spinous process and a second spinous process.
14 . The method of processing of claim 13 comprising one or more processors for determining an extension parameter information which corresponds to the first spinous process touching the second spinous process.
15 . A non-transitory computer readable medium having stored thereon a software program for causing a computer to perform a method of processing an image, the method comprising:
selecting an input image of a target spine level having at least a first vertebral body and a second vertebral body;
extracting parameter information of at least one of the first vertebral body and the second vertebral body from the target spine level of the input image;
deriving a vertebral body motion from at least one of the first vertebral body and the second vertebral body of the input target spine level of the input image;
determining a trajectory line for a motion of at least one of the first vertebral body and the second vertebral body of the target spine level; and
analyzing the vertebral body motion and trajectory line to determine a range of size parameters for surgical implant devices.
16 . The non-transitory computer readable medium of claim 15 comprising providing size parameter for surgical implant devices to at least one of a surgical planning system and an intra-operative system.
17 . The non-transitory computer readable medium of claim 15 wherein the parameter information is a box drawn from a four point markup of at least one of the first vertebral body and the second vertebral body.
18 . The non-transitory computer readable medium of claim 15 wherein a first trajectory line extends from a first corner point of a selected vertebral body of the least one of the first vertebral body and the second vertebral body.
