Vernier Picket Fence Test : A Non-Imaging Method to Localize the Radiation Isocenter with Submillimeter Accuracy

Creator:

Wong, Jennifer

Abstract:

Vernier Picket Fence (VPF) offers a method to achieve submillimeter accuracy for aligning the QA phantom to the radiation isocenter without the use of x-ray imaging. VPF tests are read similarly to vernier calipers. The maximum detector signal determines the optimal matching between MLC defined dose strips and detector positions....
