Computed tomograph GE Healthcare Optima CT540

At the heart of the Optima CT540 is ASiR technology, a revolutionary iterative reconstruction method. The Optima CT540 Computed Tomography System is a reliable and cost effective solution for high quality diagnostic imaging. The ergonomic design of the system provides a comfortable user experience and allows patients and clinicians to stay in the comfort zone while conducting examinations. In addition, a wide network of technical support services using digital technologies and remote access to the system, as well as numerous training opportunities, allow the user to receive assistance at any time and be confident in the results of their work.

Advantages

• Speed with IQE technology

With IQE technology, scanning speed becomes unsurpassed - a 70 cm chest, abdominal and pelvic region can be examined in 10 seconds. Increasing the pitch of the spiral allows you to cover more anatomical regions while maintaining high image quality. In addition, GE's Varispeed feature helps you select the right acquisition speed for your procedure requirements. The method of direct multiplanar reconstruction allows obtaining images almost instantly - at a speed of 22 images per second.

• High image quality with Volara Digital acquisition system

With a 20% increase in sampling rate, image quality remains superior in undersigned areas (shoulder, hip, metal objects, overweight patients, etc.).

• Optima CT540 with built-in ASiR enables dose reduction

The ASiR reconstruction algorithm makes it possible to reduce the current in the process of obtaining diagnostic images and, consequently, to reduce the radiation dose. Using the ASiR feature can also allow scanning at lower currents and with less anode heat, reducing the chance of tube cooling delays.

• A new level of workflow optimization

The Optima CT540 is packed with features that streamline and simplify your workflow while maintaining a high level of clinical efficiency and accuracy throughout your workflow. You can quickly switch between standard patient positioning and emergency computed tomography, work in real-time pre-scan or auto-start contrast study - the result is consistently high image quality and accuracy.

• Built-in ASIR function. A revolution in radiation dose management.

The ASiR feature can help clinicians reduce radiation dose while maintaining diagnostic image quality. In addition, it allows you to increase low-contrast resolution. The ASiR feature changes your idea of dose when scanning various anatomical structures. According to customer feedback on the ASiR function, its use allows you to achieve excellent diagnostic image quality at a low radiation dose, regardless of the type of examination being performed and the location of the study area.

• VISR function

Image Space Volumetric Reconstruction (VISR) is based on 3D filters that reduce image noise (standard deviation) without compromising spatial resolution, providing clear visualization of the structures of the nervous and cardiovascular systems and obtaining high-quality diagnostic images at lower current values.

• OptiDose function

Radiation dose reduction is achieved by combining ASiR with GE Healthcare's proven OptiDose technologies to reduce dose at the source level. They include 3D modulation that automatically adjusts the current while scanning along the x-y-z axes. For imaging purposes, collimation prior to irradiating the patient to block X-rays is not required; the width of the radiation beam is optimized to improve the geometric parameters of the radiation. Color-coded pediatric protocols make examining pediatric patients easy, dividing pediatric patients into eight color-coded categories based on their height and weight to help clinicians choose the right scan method for a particular child's body size . After each scan, an easy-to-store, structured DICOM dose report is generated that contains dose parameters and a summary of the procedure performed.
