In our Image Reconstruction team we develop state‑of‑the‑art algorithms and software for cone‑beam computed tomography (CBCT) image processing and reconstruction. Varian’s treatment delivery systems use our software to reconstruct 3D and 4D images of the patient’s anatomy. The images are nominally used for patient positioning on the treatment machine, with recent advances in image quality opening up their potential to be used also for replanning and adaptive radiotherapy. Our work focuses on further optimizing 3D and 4D image quality and developing innovative, product‑oriented algorithms in Varian’s clinical solutions.
Job Responsibilities
Implement new methods, conduct feasibility studies and integrate selected algorithms in Varian’s product line
Use parallel programming (GPU) to enhance performance of existing reconstruction algorithms
Perform imaging experiments in the lab for testing, proof‑of‑concept and troubleshooting investigations
Document design and test specifications of CBCT reconstruction algorithms
Assist product support engineering (PSE) in troubleshooting
Conduct literature research in the CT/CBCT reconstruction domain
Job Qualifications
