About

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.

Full description

The scanner sterilization will largely follow procedures used currently for cameras and microscopes: the scanner will be draped in a disposable drape custom manufactured for the device by a leading instrument drape manufacturer (Medline). The drape will be windowed with a sterilized shatterproof plastic optical window. Standard hospital procedures will be followed for the disposal of instrument drapes. The drape will be sterile and wrapped in the conventional manner, and the drape itself will be disposable. Prior to surgery, the drape, window and frame will undergo the same sterilization procedure as other equipment. If window transparency is compromised during surgery, it can be cleaned with a cleaning agent.

The scanner will illuminate the craniotomy region with light for the duration of its use, which may be for the duration of the surgery. The scanner will be anywhere from 8 to 12 inches away from the patient, illuminating the subject's brain by the scanner light for 2 minutes at a time, or continuously, either with or without maximum overhead lighting.

For each patient, the duration of obtaining data will last for the duration of the clinical operation procedure. The 3D Scanner on and off time would add less than 5 minutes to the procedure, not including measurement time.

Inclusion criteria

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.

Exclusion criteria

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.
