Brief Summary
A prospective non-invasive data/image collection for evaluation of the performance of the Advanced Scanners 3D scanner during brain surgery. The primary objective is to evaluate the performance of the scanner in determining the brain surface shape over multiple time points during craniotomies (surgical opening into the skull), and present those shapes in full color, with high resolution in all three coordinates of 3D space. A secondary objective is to use the measurements to determine brain shift as a function of time.

Outcome Measures
Primary Outcomes (1)
Brain-shift measurement
Measure brain-shift in human subjects' brains with our scanning technology, and compare with preoperative MRI or CT, and, optionally, with inter-operative or postoperative MRI or CT scans. Measurements will include changes, measured in millimeters, of the surface anatomic features of the brain from the optical scans. Overall topological changes will also be measured between pre- and post-operative CT/MRI imaging of the patient with the optical scans. All these measurements will be performed using co-registered surfaces, reporting specifically computer-determined measurement of distances between those surfaces.

The study cohort
The study will enroll 10 subjects meeting the eligibility criteria, with the expectation to obtain complete data from at least 6 subjects.
Interventions
For use to monitor brain shift during craniotomy
Eligibility Criteria
Subjects seen by Dr. Anat I. Patel (neurosurgeon) and scheduled for craniotomy at St. David's North Austin Medical Center are the potential population for this study.
You may qualify if:
- Male or female ≥ 6 years of age at Visit 1.
- Clinically planned for craniotomy, including for malignant tumors, whether awake or under general anesthesia.
- Able to provide written informed consent (and assent when applicable) - by subject or subject's legal representative - and agrees to comply with the requirements of the study.
You may not qualify if:
- Language problems that would prevent from properly understanding instructions.
- Requirement of an interpreter.
- Patients who are excluded from consideration for the clinical operation are therefore excluded from the research study.
- Special populations: pregnant women, prisoners.
