Programmable FOV
a. Readout time is for full FOV. Programmable ROI modes readout time is dependent on the programmed matrix size.
b. Max Linear Dose is to be considered a typical value with CsI scintillator and RQA5 beam.
c. 3 × 3 Full FOV modes image area is equivalent to a 1 × 1, 4080 × 3072.

Image Corrections
The X-ray detector includes real-time corrections for offset, gain and defects.
image corrections pipeline.
The X-ray detector will store three calibration files per mode: offset, gain, and defect. These files
are used for on-board corrections during image acquisition. Calibration functions for gain and
offset are provided in the API and can also be performed using Viva Pro. More information can
be found in 05834 Varex Smart Panel (VSP2) Software Interface Specification.
