Description
We present our technical studies of an automated slow control system able to control
a small animal PET (Positron Emission Tomography) Gantry. It consists of a
cable-less powered embedded acquisition cards, that include the detectors, that are
wireless and interfaced with the main data acquisition system; both connected to an
event builder computer station.
The gantry angle position is red out trough an opto-scanner allowing angular
precision of 0.0046° for an absolute angle position coding. The Gantry, free and
continuous, rotation is controlled with an embedded microcontroller. The later
ensures real time interface with the global data acquisition system (daq). Individual
absolute detector position can be acquired independently with an under study
dedicated laser calibration system.
