Purpose:
With single room proton centers uprising throughout the world, it is very important for the administration and hospital to determine the appropriate size of the proton team to support the state-of-art proton unit with PBS technique. Based on our half year operation with IBA ProteusONE, the first compact PBS proton unit in the world, we recommend a compact proton infrastructure which could ensure the single room proton center’s daily clinic operation, commission and technique development.
For the machine acceptance and commission, we would recommend 2 to 4 physicists working two-shift. The basic acceptance and commission normally take around 2 to 3 months. Currently we are treating 10 patients per day with 60% prostate patients 40% cranial and head&neck patients. The infrastructure of the current ProteusONE proton team includes: 1 full time physicist for proton planning and daily clinic operation, 1 full time physicist for chart checking and QA, 0.5 physicist for continuing technique development and 2 therapists for daily treatment. Although current our proton unit uptime is 98.5%, proton machine is a complex unit which has some unexpected down time due to the technique challenges. It is very necessary for the individual clinic to establish contingency plan in case of the proton machine down time.
For a hospital to consider building a team for operate a single room PBS proton unit for daily operation treating 20 – 25 patients:
2.5 proton physicists
During daily operation: 1. Oversee the daily proton therapy performance. 2. Planning support physicist ensure the plan accuracy and robustness 3. Chart Check and patient QA.
During machine commission: 1. In charge of CT calibration and device calibration 2. In charge of PBS beam modeling and commission. QA procedure developments. 3. In charge of planning technique development .
1 to 2 Proton Dosimtrists, 4 proton therapists.
