About this study

Official title: An Automated Deep Brain Electrode Implantation System Assisted by Simultaneous Imaging and Electrophysiology Navigation

  1. Analysis of the correlation between imaging and electrophysiological signals.
  2. Real time analysis method for optimal implantation position.
  3. Simultaneous Imaging and electrophysiology navigation.
  4. Accuracy and security verification of navigation system.

Expectation(Hypothesis):

Develop an automated DBS surgical navigation system based on multimodal brain imaging data and neural electro-physiological signals, which can achieve real-time linkage navigation between imaging and electrophysiology, and automatically generate the optimal implantation position of DBS electrodes based on imaging and electrophysiological information through deep learning algorithms, thereby reducing DBS electrode implantation position errors and improving surgical efficacy.

Read the detailed description

Firstly, we choose patients who voluntarily participate in this clinical study and sign an informed consent form, whose age range from 35 to 75 years old, regardless of gender. Their clinical diagnosis is consistent with typical Parkinson's disease or muscle tone disorders, and the medical history is within 20 years. Additionally, their MRI examination excludes obvious structural changes. Last but not least, patients should have basic normal vision and hearing, and good compliance.

Then, we collect general information of enrolled patients, input preoperative MRI images of the head and thin-layer CT scans with a head rest on the surgical day into the system for image processing. Connect this system to the electrophysiological signal acquisition system during DBS surgery and record the electrophysiological signals. The first one is to analyze the degree of matching between the position and length of nuclei displayed by electrophysiological signals and imaging information, and verify the matching of the intraoperative imaging electrophysiological linkage tool. At the same time, compare the position and length information of nuclei prompted by the tool with the judgment of the surgeon, and analyze the differences between it and the judgment of clinical doctors. The second one is to using an automatic analysis tool for electrophysiological signals, record the analysis results, compare the optimal electrode implantation position automatically calculated by the system with the final implantation position selected by the surgeon, calculate the differences between the two, and further analyze the differences with the judgment of clinical doctors.

Finally, This study will test the accuracy and usability of the two tools involved in DBS surgery, and collect the following indicators: 1) the length of nuclei and the position of nucleus boundaries on imaging data, the length of nuclei and the position of nucleus boundaries on electrophysiological data, the matching degree between imaging and electrophysiology, and the consistency of nucleus information interpreted by clinical doctors after imaging electrophysiology integration; 2) Using an automatic analysis tool for electrophysiological signals, record the analysis results, compare the optimal electrode implantation position automatically calculated by the system with the final implantation position selected by the surgeon, calculate the differences between the two, and further analyze the differences with the judgment of clinical doctors.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The accuracy of automatic electrode position analysis tools

    The best placement of the electrode (indicated by coordinates) is compared with the final placement of the implant selected by the surgeon (indicated by coordinates), then the difference between the two is calculated in millimeters as the outcome measures.

    Measured: 2025.12

Secondary outcomes (1)
  1. The matching of image-electrophysiology linkage tools

    Record the boundary of the nucleus (in millimeters) on the imaging data and the boundary of the nucleus (in millimeters) on the electrophysiological data. The difference between these two nuclear information data is calculated as the outcome measures to verify the image-electrophysiological matching.

    Measured: 2025.12

Questions about this trial

What is this clinical trial studying?

An observational study of Advanced Parkinson's Disease and Refractory Epilepsy, run by Beijing Tiantan Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 2 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The accuracy of automatic electrode position analysis tools (time frame: 2025.12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 May 2024.
