Surgical navigation processors and systems

Abstract

Disclosed are methods and systems used with surgical navigation systems that enable a user to generate an optimized anatomical dataset for a spine level of interest. The systems and methods allow users to determine a target geometry for a spinal level targeted for spinal surgery. Additionally, the user can project loads across the spinal orthopedic implants and determine a projected subsidence over time.

What is claimed is: 
     
         1 . A processor for use with a surgical navigation system used for spinal surgery wherein the processor is programmed to execute:
 receiving an input dataset comprising one or more medical images containing a spinal level of interest and one or more image-derived measurements for each medical image, wherein the one or more image-derived measurements are selected from an alignment measurement, a lordosis measurement, a translation measurement, an angulation measurement, and a disc height measurement;   allowing a user to specify a data presentation by selecting one or more of the image-derived measurements and by further selecting at least one of a minimum value and a maximum value;   identifying a specific image view corresponding to the data presentation wherein an output of an identification process is a reference to an image that corresponds to the user specified data presentation; and   generating comparative data between a current status of the patient wherein the generated comparative data uses a measurement from one or more image captured intra-operatively via the surgical navigation system and the data presentation.   
     
     
         2 . The processor of  claim 1 , wherein the image-derived measurement includes measurements that are derivative to the measurements included in the input dataset. 
     
     
         3 . The processor of  claim 1 , wherein the comparative data generated includes one or more of a generated image with a template, a generated image without a template, and a generated image compiled from multiple imaging modalities. 
     
     
         4 . A processor for use with a surgical navigation system used for spinal surgery wherein the processor is programmed to execute:
 receiving a pre-operative dataset and an inter-operative dataset, wherein each of the pre-operative dataset and inter-operative dataset comprises one or more medical images containing a spine region of interest as well as a dataset of location values associated with a four-point registration of each vertebral body visible within the spine region of interest;   allowing a user of the surgical navigation system to specify an input dataset for each vertebral body pair within the spine region of interest; and   rendering a block diagram of a spine, by using the four-point registration dataset from the input dataset selected by the user.   
     
     
         5 . A machine readable medium containing instructions stored on a non-transitory computer readable medium that, when executed by a computing device, cause the computing device to perform a method, the method comprising:
 receiving an input dataset comprising one or more medical images containing a spinal level of interest and one or more image-derived measurements for each medical image, wherein the one or more image-derived measurements are selected from an alignment measurement, a lordosis measurement, a translation measurement, an angulation measurement, and a disc height measurement;   allowing a user to specify a data presentation by selecting one or more of the image-derived measurements and by further selecting at least one of a minimum value and a maximum value;   identifying a specific image view corresponding to the data presentation wherein an output of an identification process is a reference to an image that corresponds to the user specified data presentation; and   generating comparative data between a current status of the patient wherein the generated comparative data uses a measurement from one or more image captured intra-operatively via the surgical navigation system and the data presentation.   
     
     
         6 . The machine readable medium of  claim 5 , wherein the image-derived measurement includes measurements that are derivative to the measurements included in the input dataset. 
     
     
         7 . The machine readable medium of  claim 5 , wherein the comparative data generated includes one or more of a generated image with a template, a generated image without a template, and a generated image compiled from multiple imaging modalities. 
     
     
         8 . A machine readable medium containing instructions stored on a non-transitory computer readable medium that, when executed by a computing device, cause the computing device to perform a method, the method comprising:
 receiving a pre-operative dataset and an inter-operative dataset, wherein each of the pre-operative dataset and inter-operative dataset comprises one or more medical images containing a spine region of interest as well as a dataset of location values associated with a four-point registration of each vertebral body visible within the spine region of interest;   allowing a user of the surgical navigation system to specify an input dataset for each vertebral body pair within the spine region of interest; and   rendering a block diagram of a spine, by using the four-point registration dataset from the input dataset selected by the user.   
     
     
         9 . A product comprising one or more tangible computer-readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one processor, enable the at least one processor to cause an experience management system to:
 receive an input dataset comprising one or more medical images containing a spinal level of interest and one or more image-derived measurements for each medical image, wherein the one or more image-derived measurements are selected from an alignment measurement, a lordosis measurement, a translation measurement, an angulation measurement, and a disc height measurement;   allow a user to specify a data presentation by selecting one or more of the image-derived measurements and by further selecting at least one of a minimum value and a maximum value;   identify a specific image view corresponding to the data presentation wherein an output of an identification process is a reference to an image that corresponds to the user specified data presentation; and   generate comparative data between a current status of the patient wherein the generated comparative data uses a measurement from one or more image captured intra-operatively via the surgical navigation system and the data presentation.   
     
     
         10 . The product of  claim 9 , wherein the image-derived measurement includes measurements that are derivative to the measurements included in the input dataset. 
     
     
         11 . The product of  claim 9 , wherein the comparative data generated includes one or more of a generated image with a template, a generated image without a template, and a generated image compiled from multiple imaging modalities.
