Quantitative Standard Pulsating Phantom QSP-3DALT-OVAL is a quantitative phantom developed for assessment of spectral CT that simulates behavior of an organ. Also, it enables quantitative assessment of beam hardening artifact.

A phantom part moves upward, downward, forward, backward, rightward and leftward driven by a motor.
The movement is controlled by six preset patterns (simulated breathing and simulated ventricle behavior) as well as manually.
The phantom part is made up of PP and it can hold up to 15 small containers of which has an inner diameter of 18mm inside. Various substances like contrast agent can be put into those small containers in a fixed amount.
Containers with smaller inner diameters are optionally available (Inner diameter smaller than 0.5mm is OK).

The movement can be switched between 2D and 3D modes by a knob. With 2D mode, the movement is limited to upward and downward like QSP-1. With 3D mode, the phantom moves upward, downward, forward, backward, rightward and leftward.
Pulsation synchronizing pulses can be output with an ECG interface.

The upward and downward movement can be controlled by a cam between 0 and ±24mm stroke. The phantom moves forward, backward, rightward and leftward in proportion to the upward and downward movement.
Small containers with special shape are optionally available.
