CE CT data-set

Two different data-sets of lungs infected with tumours of varying stages were available for analysis. The first data-set which was earlier used in our preliminary research was a contrast enhanced (CE) CT angiography DICOM images referring to 11 patients (6 males and 5 females with age 63 ± 8 years old with lung cancer greater than 10 mm2), having a resolution of 12 bits per pixel (bpp). The CE images were acquired using an Elscint CT-Twin scanner ─ after injecting a dose of an iodine contrast agent into one of the large veins of each patient ─ with X-ray tube voltage and current of 140 kV and 200mAs, a 10 mm slice thickness with matrix size 512 x 512, field of view (FOV) 430mm, 0° gantry angulation and B reconstruction filter.
