| 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 (249 mm to 346 mm average diameter) demonstrating the effect of patient size on Hounsfield number in CBCT in vivo. |
