Siemens Symbia T6 SPECT/CT

The Siemens Symbia T6 is a dual-detector SPECT/CT scanner featuring a 6-slice diagnostic CT, high-definition (HD) detectors, and a 500 lb (227 kg) weight limit. Designed for optimized cardiac, oncology, and general imaging, it offers rapid imaging with low dose, {Link: IQ SPECT technology, and automated workflows. 

System Software: VB10B

Tube Type/Model: Dura 422-MV / 5534776

Tube DOM: February 2011

System Specifications:

• Modality: Dual-head SPECT camera integrated with a 6-slice diagnostic CT scanner. The CT is upgradable to 16 slices.
• Gantry Aperture: The gantry has a 70 cm (27.6 in) aperture.
• Patient Bed: The patient bed utilizes a 15 mm thick carbon fiber pallet for minimal attenuation and can support patients weighing up to 227 kg (500 lbs). The minimum bed height is 53 cm (21 in) for easy patient access.
• Collimation: The system is compatible with various collimators, including Low-Energy High-Resolution (LEHR) and Medium-Energy Low-Penetration (MELP). It features an integrated automatic collimator changer.
• Image Reconstruction: Employs advanced reconstruction technologies such as Flash 3D iterative reconstruction, which can offer up to 24% higher resolution compared to conventional methods. It also features IQ•SPECT for faster cardiac imaging. 

Key Technical Specifications:

• Detector Type: Dual-head Variable Angle (76° or 90° for cardiac, 180° for general).
• Crystal Thickness: 3/8" or 5/8" options.
• Detector Size: Large field of view (LFOV), 21" x 15.25".
