Product Overview
EXCELLENT
image quality
Zeedas CT equips with highly reliable liquid metal bearing X-Ray
tube,ultra low noise detector system and high definition image
reconstruction engine.These three key elements build a solid
foundation for the excellent image quality.
● X-ray Tube
Liquid metal bearing effectively reduces the wear and tear,
significantly extending the lifetime of X-ray tubes and reducing
maintenance cost for hospitals.
● Detector System
With 9 US and China utility patents,Aegis CT detector system is
characterized by light weight,small size,and high integration,
showing performance,quality and ingenuity of design.
● Reconstruction Engine
Equipped with GPU and SSD,reconstruction engine has higher
performance,faster computing speed and lower energy
consumption compared with traditional computer with only
CPU and hard disk drives. POWERFUL 。
system performance
Zeedas CT with 50 kW HVPS,864 kHU/min X-ray tube,and 60 fps
reconstruction engine,is ideal for facilities with high volume
patient diagnosis.BOZWIN also safeguards the quality and reliabil-
ty by controlling the process of development,production,sales
and services.Zeedas CT 128 Version 2.0
EASY
workflow
Zeedas CT ergonomic design embeds intelligence into workflow to make it easy for operators to use,reducing work load by improving efficiency.
● Operator user interface can intelligently recommend scan protocols for past patients by automatically searching scan records.
● Starting a scan with as few as three clicks,reducing patient wait time.
● Workflow is designed with navigation functions to make it simple to learn,allowing a novice operator to complete a CT scan right away.
● One-click filming saves 30%work load so that a technician can spend more time on patients.
● High definition screen on the gantry displays patient information and highlights target scan area.It facilitates operator’s verification process thus minimizing errors.
LOW
operating cost
Liquid metal bearing has higher reliability and longer lifetime compared with traditional ball bearing x-ray tubes.It is projected to save 27%of X-ray tube replacement cost over lifetime of a CT system.
Zeedas CT has a compact design,requiring a minimum footprint for a CT room.
The low energy consumption design also saves hospitals’electricity.
Key Specifications
Detector System
Zeedas CT’s detector system is characterized by lightest weight,
smallest size,and highest integration among CT detector systems
in the industry with 9 US and China utility patents.
Zeedas CT system’s anti-scatter grid (ASG)features 13 mm high
tungsten plates,absorbing at least 97%scattered X-ray.The inside
temperature of the detector system is kept within +/-0.2℃ via
intelligent temperature control mechanism minimizing tempera-
ture’s impact on detector’s performance.
Zeedas CT realizes the shortest analog signal path through highly
integrated design.This greatly reduces noise interference along
analog signal path for A/D conversion and lays solid ground for
excellent image quality.
Zeedas CT’s 0.625 mm slice thickness is among the thinnest in the
industry allowing a radiologist to see smallest structure clearly and
provide accurate diagnosis.

X-ray Tube
Zeedas CT equips with liquid metal bearing X-ray tubes,previously only available to high end CTsystems.Compared with the traditional ball bearing technology,liquid metal bearing features ultra-high heat dissipation and ultra-low performance degradation over time.
Per IEC60613 standard,heat capacity no longer represents the true performance of X-ray tubes.Instead it defines CTSPI (CT Scan Power Index)to reflect the continuous scanning capability by assessing multiple factors including heat capacity and cooling rate.

CT Gantry
High definition screen on top of Zeedas CT’s gantry displays
patient information and highlights target scan area.It facilitates
operator’s verification process thus minimizing errors.
When a CT scan requires a patient to hold breath,Zeedas CT not
only supports multiple languages to prompt the patient,but also
has indicator light and visible countdown timer to help the patient
get best images.

Zeedas CT is designed with special cover for the table cushion,
making it easy to clean and sanitize with flaps to prevent fluids
from entering the scanner.This improves the reliability and

Image Reconstruction
Real-time Reconstruction
The GPU and SSD in Recon engine enables real-time image reconstruction at 60 fps making high definition image avail- able real-time during a scan.This allows technicians to optimize scan procedures.
Post Reconstruction
Zeedas CT allows image reconstruction after scan is complete.This allows radiologists to perform additional image reconstruction using the same raw data.The image reconstruction user interface allows users to adjust priority of the image reconstructions.
