*QSP-1 is a product developed jointly by Fuyo Co. Ltd., Hong Kong Yowa Hospital and Beijing Hospital.
Quantitative Standard Pulsating Phantom QSP-1 has been developed for function evaluation of CT spectral imaging and dual energy imaging, which enables simulation of organ movement. Also, it can be used to quantitatively evaluate beam hardening artifact.

The phantom moves upward and downward by a motor. The movement is selected from six preset patterns (mock respiration and ventricle movement) or the phantom is manually controlled.
The phantom part is made up of pp and it can hold up to nine small containers inside. Various substances like contrast agent can be put into those small containers in a fixed amount. Nine small containers each of which has an inner diameter of 18mm are available as standard. Containers with smaller inner diameters are optionally available (Inner diameter smaller than 0.5mm is OK).

The vertical movement can be controlled by adjusting the cum within the range of 0 to ±20mm.
Pulsating synchronized pulses can be transmit- ted by ECG interface.
