A Machine Vision Platform for Brain Surgery.


 

According to an FDA warning, errors in the navigation systems used by surgeons are leading to “deaths, serious or life-threatening injuries”.

So we built a uniquely capable 3D optical scanner to address the dominant error in open brain surgery, “brain-shift”.

Solving this problem will preserve healthy brain tissue for the patient and reduce their time under anesthesia while saving U.S. hospitals billions in costs associated with failed and aborted procedures, extended recovery periods, and uncompensated readmissions.

Taking the guess work out of brain surgery.


 
 

How our solution for brain-shift works:

Pre-Operative Problem


Preoperative MRI

Preoperative MRI

Surgical navigation systems rely on the patients  preoperative MRI- to guide the surgeon during surgery.

But, the brain is continuously changing shape during the procedure.

Intraoperative Solution


Intraoperative optical scan

Intraoperative optical scan

During surgery, our 3D optical scanner tracks sub-millimeter changes to the exposed brain. We can use this data to simulate brain shift.

Corrected MRI

Corrected MRI

We repeatedly update the navigation system with corrected MRI’s

Post-operative Benefits


For Patients   – preservation of healthy brain tissue, shorter anesthesia time leading to faster recoveries and fewer complications    For Surgeons   – able to perform the planned procedure faster and more precisely    For Hospitals   – reduced cost associated with extended recoveries, failed or aborted procedures, and uncompensated readmissions

For Patients – preservation of healthy brain tissue, shorter anesthesia time leading to faster recoveries and fewer complications

For Surgeons – able to perform the planned procedure faster and more precisely

For Hospitals – reduced cost associated with extended recoveries, failed or aborted procedures, and uncompensated readmissions

 
Navigation systems show where the brain was, not where it is.

Intraoperative Solution

 
Using the patient’s preoperative images, our computer vision platform will construct a 3D computer-based mechanical model of that patient’s brain.

During surgery, our uniquely-capable 3D optical scanner will continually track sub-mm changes to the exposed brain. We will use this data to update the model, simulating brain shift.

Our system will output a corrected MRI reflecting the updated position of the patient’s anatomy. This corrected MRI replaces the old one in the surgeon’s image-guided navigation system. This process is repeated as needed throughout the procedure.

Postoperative Benefits


  • For the patient, we preserve healthy brain tissue and shorten the time under anesthesia leading to faster recoveries with fewer complications.

  • Surgeons can perform the procedure are planned, faster and more precisely.

  • Reduced Hospital costs associated with extended recovery times, failed or aborted procedures, and uncompensated readmissions.
