11Compared to conventional automatic exposure control (AEC) - e.g. available with Artis Q. In clinical practice, the patient dose reduction obtained by the feature described depends on the clinical task, patient size, C-arm angulation, and anatomical location. The dose reductions stated were assessed by using uniform phantoms and including mathematical models of the object sharpness and motion. Data on file and results may vary.
12Requires external 3rd party software applications.
13The dose reductions were achieved with the CNR-driven exposure control comparing to the detector-driven exposure control. They were obtained using a phantom composed of PMMA and aluminum plates to reproduce x-ray absorption and scattering in 2.5-40 cm ofpatient equivalent thickness. Contrast produced by a 0.25 mm thick iron foil, located in the isocenter, and the surrounding noise were measured. The contrast to noise ratio was calculated, considering the contrast- reducing (blurring) effects of the tube focus and object motion. Patientequivalent thickness refers to the physical thickness along the x-ray path excluding air cavities of a body having chemical element compositionidentical to the human body.

21The dose reductions were achieved with the CNR-driven exposure control comparing to the detector-driven exposure control. They were obtained using a phantom composed of PMMA and aluminum plates to reproduce x-ray absorption and scattering in 20-40 cm ofpatient equivalent thickness, here referred as middle and high attenuations. Contrast produced by a 0.01 mm thick platinum foil, located in theisocenter, and the surrounding noise were measured. The contrast to noise ratio was calculated, considering the contrast-reducing (blurring) effects of the tube focus and object motion. Patientequivalent thickness refers to the physical thickness along the x-ray path excluding air cavities of a body having chemical element compositionidentical to the human body.
