Siemens Symbia E Single Head Gamma Camera

The Siemens Symbia gamma-cams are another of the most used Siemens gamma-cams in the world. Siemens has provided several configurations of the Symbian nuclear medicine camera to meet the various requirements of nuclear medicine imaging. The Siemens Symbia gamma-camara has been offered in four different models by Siemens.
Single-head gamma camera or single head Siemens Symbia E
The Symbia E’s single-head core camera has the smallest size of the four mixed models of the Siemens Symbia E. The Single-Head core camera is suitable for general purpose shooting, featuring a relatively large gantry and fast collimator switching system called BICORE.
The Siemens Symbia E Dual Head
The dual-head Symbia E Dual-Head Variable Angle Camera, which enables the angles of the detectors in 180°, 90° and 76° to allow the system to prepare the sensitivity and power of the Gamacmera device for general scanning, cardiovascular, oncology and neurological scanning.
The Siemens Symbia S Dual Head Gamma Camera
Siemens’ dual-detector gammacamra camera has the same features as the Symbia E Dual-Head, but it also has a number of other additional features, including: It has an automatic collimator switching system, including an in-system ECG option and upgradeable to TruePoint SPECT-CT.
SPECT-CT System Symbia T (T2, T6, T16)
Siemens’ Symbia T system combines a dual-head variable angle gamma camera with a two-slice CT scanner for attenuation correction (piece T or T2=2), advanced imaging of oncology and neurology (with a T6 slice CT 6 slice) or excellent oncology coverage (using a T16 CT 16 slice machine).
The field of view of the Siemens Symbia gamma-camara is large and rectangular with dimensions of 53.3 cm x 38.7 cm with 59 PMT per detector.
The crystal used in the Siemens Symbia system is made of sodium iodide with a thickness of 9.5 mm or 15.9 mm and 59.1 x 44.5 cm.
