This dataset can build the\ninternational capacity for prototyping and evaluating new CT ventilation imaging technologies. For\nthis study, 20 lung cancer patients underwent exhale/inhale breath hold CT (BHCT), free-breathing\nfour-dimensional CT (4DCT) and Galligas PET ventilation scans in a single session on a combined\n4DPET/CT scanner.All image acquisitions were performed on a Siemens Biograph mCT.S/64 PET/CT scanner\n(Siemens, Knoxville, USA) at the Royal North Shore Hospital between 2013 and 2015. A total of 20\n4DCT scans, 20 inhale/exhale BHCT scans, 20 Galligas PET scans and 19 attenuation CT scans (missing\nfor CT-PET-VI-07) were successfully acquired for the 20 patients and included in this dataset.\nPlease see the CT-vs-PET-Ventilation-Imaging (https://doi.org/10.7937/3ppx-7s22) wiki page to learn\nmore about the images and to obtain any supporting metadata for this collection.","patients":20,"studies":22,"series":119,"instances":29491,"size_TB":0.015,"modalities":["CT","PT","RWV"],"licenses":[{"license_short_name":"CC BY 4.0","series":119,"size_TB":0.015}]}
