About this study

Official title: Clinical Study for Spectral Precise Image (SPI) Algorithm

The goal of the study is to evaluate the Image Quality (IQ), and diagnostic confidence of Spectral Precise Image for CT 7700 Scanner as compared with iDose4 as a standard-of-care reference.

Read the detailed description

Spectral Precise Image is a reconstruction technique where the system uses a trained deep learning neural network to produce an image that reduces noise while improving low contrast detectability and maintaining the appearance of traditional filtered back projection (FBP) images.

Spectral Precise Image in Spectral CT 7700 system supports both conventional and spectral reconstructions.

The study will use raw data of subjects that are over the age of 22 years and scanned by Philips Spectral CT.

Study raw data, following anonymization, will be transferred to Philips for reconstructions, both conventional and spectral images will be reconstructed with iDose4 and with Spectral Precise Image at 100% dose.

What is being measured

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

  1. Image Quality (IQ) of Spectral Precise Image reconstructions non inferior to iDose conventional images

    Primary Endpoint (Co-Primary endpoints):

    1. The Image Quality (IQ) and diagnostic confidence of Spectral Precise Image reconstructions is at least as good as (non-inferior to) iDose4 for conventional images.

    Measured: 1 day

  2. Image Quality (IQ) of Spectral Precise Image reconstructions non-inferior to iDose4 for spectral images of MonoE (MonoE 70Kev for Cardiac and for Body/ MonoE 66KeV for Head).

    Primary Endpoint (Co-Primary endpoints): 2. The Image Quality (IQ) and diagnostic confidence of Spectral Precise Image reconstructions is at least as good as (non-inferior to)-iDose4 for spectral images of MonoE (MonoE 70Kev for Cardiac and for Body/ MonoE 66KeV for Head).

    Measured: 1 day

Secondary outcomes (4)
  1. Evaluation of the differences in Image Quality (IQ) of Spectral Precise Image reconstructions versus iDose conventional images

    1. To evaluate the difference in Image Quality (IQ) and diagnostic confidence between Spectral Precise Image reconstructions for spectral images of MonoE (MonoE 70Kev for Cardiac and for Body/ MonoE 66KeV for Head) and iDose4 for conventional images.

    Measured: 1 day

  2. Evaluation of the success rate for Spectral Precise Image reconstruction

    1. To evaluate the success rate (%) for Spectral Precise Image reconstructions

    Measured: 1 day

  3. Evaluation of the interobserver agreement level for the Co-Primary endpoints

    1. The interobserver agreement level for the Co-Primary endpoints is more than 0.8.

    Measured: 1 day

  4. Evaluation of images artifacts visualization and preservation of important features

    1. Evaluation of images artifacts visualization and preservation of important features and clinical impact on diagnostic ability.

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

An observational study of Head and Body, run by Philips Clinical & Medical Affairs Global at 3 sites in United States.

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 2 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 15 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 3 sites in United States. 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?

Image Quality (IQ) of Spectral Precise Image reconstructions non inferior to iDose conventional images (time frame: 1 day). The study lists 2 primary outcomes in all. 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 15 Dec 2025.
