China Full Body Scanner Machine for Hospital

The system employs multi‑detector computed tomography (MDCT) with a 128‑slice gantry rotating at 0.4 s per revolution, delivering isotropic voxel sizes down to 0.5 mm. This configuration enables rapid acquisition of whole‑body datasets in under 10 seconds for adult patients while maintaining a dose‑length product (DLP) below 300 mGy·cm for standard protocols.

Detector panels utilize cadmium‑telluride (CdTe) semiconductor material, providing a detective quantum efficiency (DQE) above 65 % at 3 lp/mm and enabling low‑contrast detectability of 5 mm lesions at 0.5 % contrast.

The motorized patient table supports a load capacity of 220 kg, with longitudinal travel of 2100 mm and vertical adjustment range of 400 mm to accommodate bariatric and pediatric positioning. Table movement speed is programmable from 5 mm/s to 30 mm/s.

Clinical Applications in Hospital Settings

In emergency departments, the scanner enables trauma protocols that capture head, cervical spine, chest, abdomen and pelvis in a single helical run, reducing patient transfer time and facilitating rapid decision‑making for surgical intervention.

For oncology follow‑up, whole‑body PET/CT fusion benefits from the scanner’s high‑resolution CT component, allowing accurate attenuation correction and localization of lesions as small as 4 mm in soft tissue.

In pediatric imaging, dose‑reduction techniques such as iterative reconstruction and kVp modulation achieve effective doses below 1 mSv for routine whole‑body surveys, aligning with ALARA principles while preserving diagnostic quality.

Customization Options

• Can the gantry aperture be increased for bariatric patients? Yes, the standard 70 cm aperture can be optionally expanded to 75 cm without affecting rotation speed or image uniformity.
• What information is required before quotation? Required details include anticipated patient throughput, desired slice thickness, preferred detector technology (CdTe vs. conventional scintillator), and any site‑specific constraints such as ceiling height or floor load rating.
• How is quality inspected? Quality inspection involves factory acceptance testing (spatial resolution, low‑contrast detectability, CTDI), software verification per IEC 62304, and final mechanical alignment checks using laser tracker.
• What packaging methods are available for export? Units are packed in shock‑absorbent wooden crates with internal foam bracing, sealed with humidity‑indicating cards, and marked for handling according to ISPM‑15 standards.
• What is the typical production lead time? Lead time ranges from 12 to 16 weeks after receipt of purchase order, depending on configuration complexity and factory schedule.

Quality Assurance and Testing

Each unit undergoes factory acceptance testing (FAT) that includes spatial resolution measurement using a line‑pair phantom, low‑contrast detectability assessment with a 5 mm iodinated insert, and CTDI verification across three phantom sizes (16 cm, 32 cm, 38 cm).

Software validation follows IEC 62304, with unit tests covering reconstruction algorithms, dose‑reporting accuracy, and DICOM conformance. Field service engineers perform periodic calibration using a calibrated ion chamber and a uniformity phantom every six months.
