What is the Green Tube PET-CT?

he Green Tube PET-CT, an advanced medical imaging system introduced by Chancheng Central Hospital, combines cutting-edge PET (Positron Emission Tomography) technology with low-dose, eco-friendly CT (Computed Tomography) technology.

It’s core "Green Tube" features Siemens' exclusive zero-megavolt tube and magnetic levitation drive technology, integrated with multiple low-dose technologies. This system delivers exceptional imaging quality while significantly reducing radiation exposure and operational noise, providing patients with a safer, more comfortable, and environmentally friendly scanning experience.

Outstanding Advantages of Green Tube PET-CT

Ultimate Precision for Detecting Minute Lesions

Ultra-high PET Resolution: Full-field 2mm ultra-HD resolution (HD) with a 512x512 reconstruction matrix, delivering CT-comparable clarity to identify smaller, earlier-stage lesions.

Consistent Quantification Technology: A powerful tool for tumor efficacy evaluation, providing precise quantitative data (e.g., SUV values) for objective treatment assessment.

Best-in-Class TOF Performance: Industry-leading 540ps time resolution (UltraHD 2nd-gen), significantly improving image contrast and signal-to-noise ratio (up to 4x) for more accurate and confident diagnosis.

128-slice CT Platform: Combines z-Sharp flying focal spot and Triangular Prism technology to achieve 384-slice reconstructed images, enabling high-resolution, high-speed CT scanning.

Fast & Efficient, Reducing Examination Time

Ultra-fast PET Acquisition: Exclusive LSO ultra-fast crystal technology + Pico3D ultra-fast electronics double the maximum count rate while halving acquisition time, ensuring quicker exams and enhanced patient comfort.

Fastest CT Rotation: Industry-leading 0.3-second rotation speed dramatically shortens scan time.

Eco-friendly Design, Special Care for Vulnerable Groups

Siemens Green Tube Technology: Zero-megavolt tube with magnetic levitation drive ensures high-speed, quiet CT operation, significantly reducing room noise for improved patient comfort.

Ultra-low Radiation Dose: Exclusive Caredose 4D intelligent dose modulation + Edge Collimator technology minimize X-ray exposure, making it ideal for radiation-sensitive populations (e.g., children, pregnant women when necessary, patients requiring frequent follow-ups).

Sustainability: Green technology reduces energy consumption and environmental impact.

Comfort & Safety, Thoughtful Details

78cm Wide Bore: Spacious design alleviates claustrophobia, accommodating large-body patients and specialized radiotherapy positioning needs.

Magnetic Levitation Exam Table: Single-pivot cantilever design ensures equal-arm movement between PET and CT tables, guaranteeing perfect image fusion and more accurate SUV measurements for precise diagnosis.

Core Clinical Applications of Green Tube PET-CT

The Green Tube PET-CT serves as a powerful tool for precision oncology diagnosis and treatment, particularly indicated for:

1. Early Tumor Detection and Differentiation Evaluation of unexplained tumor marker elevation (e.g., CEA, CA199) Differentiation of benign vs. malignant indeterminate masses Characterization of lymphadenopathy of unknown origin

2. Precise Staging and Treatment Response Assessment in Malignancies Pre-therapeutic determination of tumor extent (staging) Accurate radiotherapy target delineation prior to radiation therapy Post-treatment (chemotherapy/radiotherapy/targeted therapy/immunotherapy) efficacy evaluation (response assessment) Detection of tumor recurrence/residual disease and differentiation between post-treatment necrosis/scar tissue vs. viable tumor

3. Additional Specialized Applications (Expertise-Dependent) Valuable for complex diagnoses in: • Cardiovascular/cerebrovascular diseases • Neurological disorders (e.g., neuroreceptor imaging)
