About this study

Official title: A Deep-learning System for Low-Dose CBCT Image Reconstruction: a Stepwise, Multicentre, Early-stage Clinical Validation Study

The goal of this clinical trial is to learn if the DeepPriorCBCT model ensure high-quality CBCT image while reducing CBCT radiation dose. The main questions it aims to answer are:

  • Can DeepPriorCBCT reduce CBCT radiation doses?
  • Is the image quality of DeepPriorCBCT reconstruction consistent with that of existing clinical reconstruction method? Researchers will compare CBCT images quality reconstruction with DeepPriorCBCT model to CBCT image quality reconstruction with existing clinical protocols to see if DeepPriorCBCT model can improve the CBCT image quality while reducing radiation dose.

What is being measured

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

  1. CBCT Images Quality Score

    CBCT Images Quality Score was analyzed by 5 radiologists using 5-point Likert scale.

    Measured: No more than 1 week

Secondary outcomes (3)
  1. The scores of lesion diagnosis from 5 radiologists

    5 radiologists from 5 medical centers will be invited to diagnosis the lesion of fully sampled machine-reconstructed CBCT images vs. undersampled model-reconstructed CBCT images.

    Measured: No more than 1 week

  2. The agreement scores given by the 25 interventionalists.

    25 interventionalists from 5 medical centers will be invited to analyze fully sampled machine-reconstructed CBCT images vs. undersampled model-reconstructed CBCT images. The scores given by the 25 interventionalists will be used for agreement score analysis.

    Measured: No more than 1 week.

  3. Radiation dose

    Radiation dose is defined as the radiation dose received by patients when undergoing one conventional-dose CBCT scan and one undersampled CBCT scan.

    Measured: No more than 1 day

Questions about this trial

What is this clinical trial studying?

A study testing Participants will receive a 1/6 views undersampling lung CBCT scan. in people with Lung Nodules, run by Union Hospital, Tongji Medical College, Huazhong University of Science and Technology at 5 sites 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 3 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: finished, as of the sponsor's last update on 18 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

CBCT Images Quality Score (time frame: No more than 1 week). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07035977, which also lists 2 linked publications.

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 18 Dec 2025.
