Latest Patents

One of Dejongh's latest patents involves updating proton stopping power maps for proton radiation therapy treatment planning. This innovative system performs deformable image reconstruction and updates relative stopping power maps using individual proton measurement data. It does not require the use of an entire proton radiography image, allowing for greater flexibility in treatment planning. The method optimally fits protons while minimizing deviations from the original or deformed RSP map, accounting for uncertainties through a covariance matrix.

Another significant patent is an iterative algorithm for proton CT image reconstruction. This system encompasses both proton radiography and proton CT, aiming to reduce range uncertainties. It provides a fast and efficient check of patient setup and integrated range just before treatment. The system addresses the range inaccuracy problem in proton therapy by directly measuring relative stopping power, significantly reducing uncertainties in treatment planning.
