Piranha & QABrowser Reference Manual
Note 1: This is valid for a tube with 14° anode angle. The HVL for a 22° anode is typically 0,5 mm
lower (@ 80 kV, 3 mm TF).
Note 2: All kerma and kerma rate ranges, inaccuracy, and resolution figures are valid for product
version 2 and higher of the Piranha.
Note 3: The Kerma rate is calculated as the Kerma (Dose) divided by the Irradiation time. See
also Waveforms and Triggers .
Note 4: The HVL range is valid if also the TF is within its specified range. For high TF at high kV
the HVL range may be limited by this.

also Waveforms and Triggers .
Note 3: The M6 (W / 50 µm Rh), M10 (W / 50 µm Ag), and M15 (W / 0.70 mm Al) calibrations are
suitable for the Hologic Selenia Dimensions and Fuji Amulet.
Note 4: The M16 (W / 50 µm Ag (Sel)) and M17 (W / 50 µm Rh (Sel)) calibrations are suitable for
Hologic Selenia with W anode..
Note 5: The M7 (W / 0.5 mmAl) calibration is suitable for Philips MicroDose Mammography
(Sectra).
