Siemens Biograph mCT Flow

Description

The Siemens Biograph mCT Flow PET/CT System represents a major technological paradigm shift in hybrid molecular imaging by replacing conventional stop-and-go bed positions with FlowMotion™ continuous patient table movement. This continuous acquisition architecture allows clinicians to customize scanning speeds dynamically based on specific anatomical zones—slowing down over areas requiring higher sensitivity while speeding past lower-priority regions. Built upon a wide 78 cm bore and paired with a high-performance CT subsystem (up to 128 slices), the mCT Flow delivers sub-2 mm spatial resolution, continuous 4D motion management, and reproducible quantification.

Key Features

• FlowMotion™ Continuous Bed Technology: Replaces bed-position overlaps with continuous, smooth movement, enabling organ-focused protocols and flexible range planning without step artifacts.

• OptisoHD Detector Array with LSO Crystals: High-density Lutetium Oxyorthosilicate scintillation crystals engineered for high photon stopping power and fine spatial resolution.

• ultraHD•PET (HD•PET + Time-of-Flight): Combines point spread function (PSF) modeling with Time-of-Flight (TOF) reconstruction to improve signal-to-noise ratios (SNR) by up to 2x and deliver crisp lesion contrast.

• Spacious 78 cm Bore & Short Tunnel: Expansive gantry aperture accommodating bariatric patients (up to 227 kg / 500 lbs), pediatric exams, and complex radiation therapy positioning setups.

• Organ-Based Protocol Customization: Software controls allow users to adjust bed speed, resolution matrix (up to $400 \times 400$), and respiratory gating parameters for individual organs in a single continuous scan.

• Adaptive Dose Reduction & CARE Dose4D: Integrated CT radiation management tools automatically adapt tube current to lower patient dose while maintaining diagnostic image sharpness.

Key Benefits

• Personalized & Organ-Specific Imaging: Scan speed and resolution can be tailored to the target disease (e.g., slower speed for head/neck, faster for legs) within a single seamless workflow.

• Enhanced Small Lesion Detectability: Continuous motion and ultraHD•PET technology remove overlap artifacts and motion blur, making it easier to identify subtle micro-metastases and primary tumors.

• Superior Patient Comfort: Smooth, uninterrupted table travel gives patients a sense of continuous progress, reducing claustrophobia and movement-related re-scans.

• Streamlined Radiation Oncology Planning: Zero-deflection patient table and wide 78 cm bore facilitate co-registration with radiation therapy positioning boards and external laser systems.

• Maximized Facility Throughput: Eliminates wasted table-stepping time, lowering overall scan duration by up to 25% and boosting daily patient volume.
