## Dataset description
This dataset contains same-day repeat CT scans of 32 non–small cell lung cancer patients, each reconstructed at six imaging settings varying in slice thickness and reconstruction kernel. Radiologist-annotated lesion contours are included as reference standards, enabling evaluation of quantitative imaging biomarkers across different reconstruction parameters.

**Number of CT volumes**: 59

**Contrast**: Unenhanced

**CT body coverage**: Chest

**Does the dataset include any ground truth annotations?**: Yes

**Original GT annotation targets**: Lung tumors

**Number of annotated CT volumes**: -

**Annotator**: Human

**Acquisition centers**: Memorial Sloan-Kettering Cancer Center, New York

**Pathology/Disease**: Non–small cell lung cancer with measurable primary or metastatic lesions

**Original dataset format**: DICOM
