Brain-Shift Monitoring Using 3D Scanning

September 29, 2025 updated by: Advanced Scanners Inc.

Pre-pilot Study of Brain-Shift Monitoring Using 3D Scanning

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed 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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

6 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

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.

Description

Inclusion Criteria:

  1. Male or female ≥ 6 years of age at Visit 1.
  2. Clinically planned for craniotomy, including for malignant tumors, whether awake or under general anesthesia.
  3. 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:

  1. Language problems that would prevent from properly understanding instructions.
  2. Requirement of an interpreter.
  3. Patients who are excluded from consideration for the clinical operation are therefore excluded from the research study.
  4. Special populations: pregnant women, prisoners.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Brain-shift measurement
Time Frame: Throughout the surgical procedure
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.
Throughout the surgical procedure

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Brain-shift measurement accuracy
Time Frame: Throughout the surgical procedure
Measurement of brain-shift in human subjects' brains with sub-mm accuracy using our scanning technology
Throughout the surgical procedure

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Operation of the 3D scanner
Time Frame: Throughout the surgical procedure
