    Article Title: Validation of a 2D dose verification systemfor intensity-modulated arc therapy
    Article Snippet: Objective: The measured dose was shown to be dependent on the angle of beam incidence and influenced by couch absorption when a 2D detector was used in a stationary phantom.. The use of a 2D array (MatriXX) in combination with a solid water phantom (RW3) dose verification system was explored, which could take into account the couch absorption influences, generate correction factors (CFs) for each detector element, and also calibrate the measured dose for accurate validation of intensity-modulated arc therapy (IMAT) treatment plans.. Methods: Based on the introduction of a homogeneous treatment bed model in the Monaco treatment planning system, CFs(θ) were constructed for all incidence angles using 6 MV photon lines in a 28 cm × 28 cm field for MatriXX at different field incidence angles (0–360) as a relative ratio of simulated and measured values.

    Article Title: THE 2023 AAPM ANNUAL MEETING PROGRAM.
    Article Snippet: Using TOPAS generated simple fields, EBT3 film and a MatriXX-PT IC array, both mechanical and dosimetric accuracy were quantified for a set of clinically representative deliveries where the automated positioning of the collimators was synchronized with the scanned position of the proton beam.

    Article Title: Proceedings to the 61 st Annual Conference of the Particle Therapy Cooperative Group
    Article Snippet: The PBS (energies 222-189 MeV) delivered 2 GyRBE to a half-cylindrical phantom with a radius of 12 cm, placed on the MatriXX 2D IC for dose verification.

    Article Title: Validation of RayStation Monte Carlo dose calculation algorithm for multiple LINACs.
    Article Snippet: Purpose: A photon Monte Carlo (MC) model was commissioned for flattened (FF) and flattening filter free (FFF) 6 MV beam energy.. The accuracy of this model, as a single model to be used for three beam matched LINACs, was evaluated.. Methods: Multiple models were created in RayStation v.10A for three linacs equipped with Elekta “Agility” collimator.

    Article Title: Dosimetric delivery validation of dynamically collimated pencil beam scanning proton therapy
    Article Snippet: For the uncollimated case, excellent agreement is observed between simulation and measurements with 2D gamma (2%/2 mm/5% threshold) pass rates of 94.6% and 100% for comparisons with the MatriXX array and EBT3 film, respectively.

    Article Title: Patient-specific quality assurance of dynamically-collimated proton therapy treatment plans.
    Article Snippet: This was accomplished by defining the error vector ⇀ ei = (Δxi,Δyi,Δdi), where Δx = (−4, −3, −2, −1, 0, 1, 2, 3, 4) (mm) represents a dose distribution shift in the xdirection (parallel to the MatriXX-PT detector array), Δy = (−4, −3, −2, −1, 0, 1, 2, 3, 4) (mm) represents a dose distribution shift in the y-direction (parallel to the MatriXX-PT detector array), and Δd = (−4,−3,−2,−1, 0, 1, 2, 3, 4) (%) is the percent change in dose, and i = 1, ..., 93 = 729 is the shift index that identifies all possible combinations of Δxi,Δyi, and Δdi values.
