Philips BrightView XCT SPECT/CT

The Philips BrightView XCT is a hybrid Single-Photon Emission Computed Tomography/Computed Tomography (SPECT/CT) system designed for nuclear medicine, featuring a compact footprint and high-resolution, low-dose CT imaging capabilities, combining a 3/4-inch crystal gamma camera with a flat-panel cone-beam CT for attenuation correction and anatomical localization. It features a 205 kg (450 lbs) patient weight limit, 91.4 cm gantry aperture, and 12-second CT rotation. The system is designed for high-resolution imaging with 1 mm isotropic voxels. 

Gantry and Physical Specifications

Patient Table

• Weight Capacity: 500 lb (227 kg).
• Dimensions: 243 cm (L) x 47.5 cm (W).

SPECT & CT Performance

• Detector Geometry: Dual-head variable angle.
• Detector Material: Sodium Iodide (NaI) crystal, typically 9.5 mm (0.375") thick.
• CT Technology: Utilizes a flat-panel X-ray detector for cone-beam CT (CBCT).
• CT Slice Thickness: Achieves high-resolution CT images with slices as thin as 0.33 mm.
• CT Dose Level: Low-dose CT, with typical attenuation correction dose of < 1 mGy CTDIVOL.
• Co-planar Imaging: Features a CoPlanar FP design, allowing SPECT and CT acquisitions without table indexing between many scans, which improves registration confidence.
• Image Reconstruction: Uses Astonish reconstruction technologies (an option) to potentially cut acquisition time in half. 

Operation and Workflow Features

• Body Contouring: Includes BodyGuard automatic contouring technology to position detectors optimally to the patient's body.
• Breathing Protocols: Supports flexible protocols that allow patients to breathe normally during both SPECT and CT for attenuation correction, enhancing patient comfort.
• User Interface: Compatible with the Philips NM Application Suite and Extended Brilliance Workspace for streamlined review and analysis.
