Canon adds enhancements to its Celesteion PET/CT system

Canon Medical Systems has added enhancements to improve workflow and image quality of its Celesteion™ PET/CT system. These include a wide range of new acquisition and reconstruction techniques, according to the Tustin, CA-headquartered company.

The CT, which includes AIDR 3D, the company’s advanced CT dose reduction technology, has a 90 cm bore. The PET has an 88 cm bore. With expansive field-of-view and time-of-flight imaging, the Celesteion combines high-performance PET and CT for all radiation and oncology imaging needs, including tumor detection, treatment evaluation, and CT simulation.

New acquisition features and techniques include:

• Variable Bed Time (vBT), enabling clinicians to adjust scan times and acquisition mode per bed position for optimal results, including faster exams;
• PET Respiratory Gating, incorporating respiratory gating into whole body PET scans to help avoid extra scans and toreduce dose while improving patient experience and workflow efficiency; and
• PET ECG Gated Scanning, offering clinicians the ability to perform PET ECG phase image reconstruction scans.

New reconstruction techniques have been added. These include:

• Clear Adaptive Low-noise Method (CaLM) +PSF. This delivers improved PET image quality by filtering out noise while maintaining contrast, offering greater clarity while preserving detail in the image as compared to Local Means Filtering; and
• Single Energy Metal Artifact Reduction (SEMAR). This software feature utilizes a reconstruction technique to reduce metallic artifact, improving visualization of implants, and supporting bone and the adjacent soft tissues.
