Using AQUA to standardize linac QA at the UMCU

26th October 2017 3pm BST


AQUA is a departmental quality management software that centralizes all of the machine QA activities, helping to manage the complexity of quality assurance requirements in a radiation therapy department. As part of an MR Linac research project, Aqua was chosen to standardize and manage QA activities. It uses a centralized database to consolidate all QA tests, procedures and results in one location and offers a workflow manager to guide the users in their day-to-day QA tasks.

In this presentation, we will review how University Medical Center Utrecht utilizes Aqua to manage and monitor QA across the radiation therapy department.




Jochem Wolthaus received his master’s degree in Applied Physics at the University of Technology in Delft (2002). He performed his master thesis project at the NKI-AVL in Amsterdam on the topic of image registration of lung cancer patients for set-up verification. This project continued in a broader PhD project entitled “Four-dimensional imaging in radiotherapy for lung cancer patients” (2009). After his PhD he started his residency in Medical Physics at the radiotherapy department of the University Medical Center Utrecht. Since 2012 Jochem is a staff member and responsible for the QA of the conventional linacs as well as the MR-Linac, which is currently under development and clinically released soon. His professional interests are linac QA, film, QA detectors/devices, image and data processing and analysis, and software development.
