QuantumEyeTM 789（256-slices）

QuantumEye series include the 256-slices and the high-end 512-slice CT apart from facilitating complex routine scans also has the full capability of becoming a valuable appliance in advanced researches. QuantumEye CT scanner stands out with such features, as DivineLight detector that has a Z-axis coverage up to 160 mm, the DivineArk gantry system that enables a rotation speed up to 0.25 seconds, and AI-empowered workflow. As a result, challenging clinical scans including one-stop stroke imaging, CTA scan as well as emergency CT scans have never been so easy and safe for both patients and clinicians.

DivineArk gantry utilizes a magnetic suspension bearing (so-called „magnetic levitation, or „Maglev”) and a direct-drive motor to achieve high-speed 0.25s rotation speed. This technology facilitates to contact-free operation between the rotor and the stator, resulting in greater acceleration to reach the specified speed quickly in the silent mode (20dB lower than the traditional one). The use of a direct-drive motor also efficiently reduces artifacts, resulting in more stable and precise imaging.

Efficient dose management:

– imA (Implemented imA technology enables the automated adjustment in the output of the tube according to the scanned anatomical region and patients’ size and weight, effectively reducing the radiation exposure while preserving the image uniformity of each slice image      .

– NanoDose Iteration Algorithm (NDI) is an innovative iterative technique for image reconstruction. It’s model-driven iteration involving tube and detector in projection space, and aims to generate sharp high-resolution images at the lowest dose possible.

– Pediatric protocol – QuantumEye 789 provides dedicated care for pediatric with 70 kV pediatric protocol, which effectively reduces the radiation while ensuring the quality of images.

 

  • Optimal design:

– Thermal Airflow Isolation Design – Effectively isolates the hot air from the outer (including the X-tube and HV generator) and inner detector.

– Ensures the thermal stability of the detector during continuous scanning.

– Greatly extends the service life of the detector and reduces the degradation of the image quality.
