Introduction

2.1 Introduction

CardioMD is a nuclear medicine gamma camera system intended for cardiac imaging. A dedicated
acquisition PC executes all acquisition protocols.
Acquisition data from the PC can be sent via DICOM to a workstation for further processing.
For use with the CardioMD system, Philips Medical Systems offer a choice of two processing
stations:
•
The Pegasys Ultra™ workstation
•
The JETStream® Workspace Cardiology Module.
For further information on these, please refer to the relevant workstation documentation
DICOM (Digital Imaging and Communications in Medicine) is a NEMA standard that defines a
means of exchanging image files and other information between DICOM compliant devices.
DICOM provides image network file transfer capabilities between the CardioMD acquisition PC
and the workstation.
Note. DICOM data transfer between the CardioMD and any workstation other than those
specified above is not a valid configuration and is not supported.

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.
