Figure Lengend Snippet: Signal amplitude from the CROSSmini detector with signal fitting and zoomed in views. Figures A, B and C, on the left, shows the signal amplitude from the CROSSmini detector of a spill duration for energy level 70.2, 150.2, and 228.7 MeV, respectively, with nominal beam current 8 MU/s. The red line represents the original signal from CROSSmini and the black line represents the piecewise fitting for the edges. On the right is the zoomed in view of the fitting. The piecewise fitting quantifies the risetime ( t rise ) and measured nominal beam current ( I 0 , measured ).

Article Snippet: The beam current was measured using a CROSSmini 2D strip ionization chamber detector array (Liverage Biomedical Inc, Taiwan) positioned at the isocenter plane.

Figure Lengend Snippet: Signal amplitude from the CROSSmini detector with signal fitting. shows the signal amplitude as a function of time measured by the CROSSmini detector and the piecewise fittings. Figures A, B, and C are measurements for energy level 70.2 MeV with nominal beam current 8, 14, and 20 MU/s, respectively. Figures D, E, and F are the measurements for energy level 228.7 MeV with nominal beam current 8, 14, and 20 MU/s, respectively.

Figure Lengend Snippet: (a) Measurement device combined with a 2D ionization chamber array and an accordion-type water phantom. (b) Typical results for PSQA. The upper and lower panels show the PC and HNC cases, respectively. The arrows on the dose distribution indicate the dose profile’s direction. (c) The gamma passing rate in the clinical cases.

Article Snippet: We performed the measurements using the PinPoint chamber and a commercial 2D ionization chamber array (OCTAVIUS Detector 1500 XDR, PTW-Freiburg GmbH, Freiburg, Germany) mounted on an accordion-type water phantom that enables the water-equivalent thickness to be changed easily [ ].
