Abstract
We determined Hounsfield numbers, using cone beam CT (CBCT), in the bladder of 27 muscle invasive bladder cancer patients treated with online adaptive radiotherapy using a Varian linear accelerator. The CBCT number of urine was found to increase by 130 from the thinnest to the largest patient (249mm to 346mm average diameter) demonstrating the effect of patient size on Hounsfield number in CBCT in vivo. © 2010 The Royal Australian and New Zealand College of Radiologists.
