About this trial

The overarching objective of the project is to develop a new C-arm interventional x-ray imaging platform that integrates both a photon counting detector and a flat panel detector to provide high image quality and quantitative spectral computed tomography (CT) image guidance will be developed to enable more accurate and safe interventional procedures for patients.

Trial outcomes

Primary outcomes

1

Mean Confidence Score for Calcifications

MDCT, PCD-CBCT, and FPD-CBCT images will be co-registered and displayed on a clinical monitor using a customized software that allows the users to toggle between energy bin images. At least 4 readers with a broad spectrum of clinical experiences (radiology residents, interventional radiology and neurosurgery fellows, and experienced physician co-investigators) will independently identify calcifications and extravasated iodine contrast (if available) and provide a 1 (low) to 5 (high) confidence score on each image.

Time frame
after participant data collection is complete (up to 1 year)
2

Mean Confidence Score for Metal Artifacts

MDCT, PCD-CBCT, and FPD-CBCT images will be co-registered and displayed on a clinical monitor using a customized software that allows the users to toggle between energy bin images. At least 4 readers with a broad spectrum of clinical experiences (radiology residents, interventional radiology and neurosurgery fellows, and experienced physician co-investigators) will independently identify metal artifacts (if any) and provide a 1 (low) to 5 (high) confidence score on each image.

Time frame
after participant data collection is complete (up to 1 year)
3

Area Under the Curve (AUC) for Calcification Detection

For all reading studies, the order of subjects and imaging modality (MDCT, FPD-CBCT, and PCD-CBCT) will be randomized; three separate reading sessions will be implemented with a washout period of at least 3 months between sessions. For calcification and iodine staining detection in the human subjects, the receiver operating characteristic (ROC) curves will be calculated using the maximum-likelihood method with the binormal model. The 95% confidence interval (CI) of each ROC curve will be estimated and the area under the curve (AUC) and its 95% CI will be calculated.

Time frame
image analysis will proceed after participant data collection is complete (up to 2 years)
