    2.2.1 Gantry The gantry forms the basis of the CardioMD gamma camera. All external devices are connected to the gantry from where the signals are distributed to the various system components. The gantry contains most of the system’s electronics, such as power supplies, motors and motion controllers.

  • Page 19: Motions

    2.2.1.2 Covers The covers of Series III CardioMD systems are slightly different from those of earlier systems, as shown in Figure 2.2 and Figure 2.3. The steel gantry construction has four main covers. Removal of these gives access to all gantry electronics and drives.

  • Page 21: Patient Table

    The height of the table is fixed. The table can be moved along its longitudinal axis by means of a motor controlled from the CardioMD hand controller. This motion is intended for fine tuning of the patient’s position relative to the detectors. There is no manual movement as part of normal operation.

  • Page 22: Power Supply

    2.2.1.5 Power Supply Power to the entire system is applied to the AC mains input on the gantry. The CardioMD has a maximum power consumption of 1800 VA (including the power consumption of the acquisition PC), which allows the CardioMD to be powered from a standard AC mains supply outlet.

  • Page 23: Detectors

    Note. The crystal has a thin aluminum cover which is biased with negative high voltage. On the CardioMD detector heads, a PMT produces an analog current relative to the light input. This current is converted into a proportional voltage signal inside each PMT assembly. Voltage signals from all PMT’s are combined in groups.

  • Page 24: Hand Controller

    A Collision Override button is also provided on the hand controller. 2.2.5 Acquisition PC The acquisition PC is connected to CardioMD via the FireWire control interface. The acquisition PC uses this interface to control detector motions and to receive corrected events from the detector.

These are: • Detector rotate • Detector Y (vertical) • Detector X (horizontal) • Table longitudinal. The table axis needs no calibration. One micro switch is used to detect center position. The state of this micro switch is read by the rotate (master) motion controller and used for automatically centering of the table as part of patient load positioning.

    12.2 Overview The CardioMD AC Option consists of two transmission scanners that mount onto the end piece of each CardioMD detector. The two scanners are identical, with the exception that they contain different software in the motion controller controlling the movement of the line source. For this reason, the two scanners are mechanically coded to prevent them being swapped by mistake.
