PTP-IQ: Paired texture phantom & image quality data for CT

We present PTP-IQ, a public repository of Paired Texture Phantom and Image Quality data. The dataset consists of paired CT acquisitions of image quality and texture phantoms acquired under identical specified conditions across multiple scanner models and protocols. This dataset uniquely enables researchers to directly correlate traditional image quality metrics (3D modulation transfer function, 3D noise power spectrum, and contrast-to-noise ratio) with QIF measurements, particularly texture features that are inherently sensitive to image quality variations. The details of this dataset have been submitted for review to Medical Physics. We will update the repository with details from the manuscript upon publication.
