1.6.3. Dose to Patient
Skin Dose Levels
The skin dose levels in normal use may be high enough to cause deterministic effects. The availability of the different settings has a considerable
effect on the radiation quality, the delivered dose rate and the image quality.
Patient Entrance Reference Point
Air Kerma (Kinetic Energy Released per unit Mass, i.e. Dose) is an indication of the radiation delivered to the patient entrance reference point, a
point in space, and is measured in the units of Grays (Gy). The System determines the patient entrance reference point as a point along the central
X-ray beam axis 70cm from the focal spot (30cm from the image intensifier entrance).
Selection of the patient entrance reference point is based on international convention and typical usage of a multi-use mobile
fluoroscopy system. This point should represent a typical intersection of patient surface and the X-ray beam axis.
Radiation Data
The measurement is performed at patient entrance reference point. Following dosimetric data are typical values in normal use cases. There might
be with some tolerance in actual use cases.
The following data are for Brivo OEC 715, 785 with I.I.(23XZ4ST/BS).
