Lymphoma Staging

86-year-old male, lymphoma staging. 12.5mCi F-18 FDG was injected intravenously. CT and PET images were acquired on a Canon Medical Systems Celesteion PET-CT scanner after a 90 minute uptake period.

Largest PET/CT bore provides more room to move

90 cm CT bore for an improved patient experience and better access for Oncology planning and therapy devices.

  • 90 cm CT bore
  • 88 cm PET bore

Overcome the limitations of a 50 cm field of view.

  • 70 cm True Scan FOV, CT
  • 70 cm PET FOV


The next step in the evolution of noise reduction technology.

PET Detector

A PET/CT scanner built around your patient with safety and satisfaction a primary consideration.

  • Improved lesion detection, time of flight resolution, 394 ps typical TOF
  • 70 cm CT and PET field of view for greater image accuracy
  • 90 cm CT bore and 88 cm PET bore designed for an improved patient experience

New Reconstruction: CaLM
(Clear Adaptive Low-noise Method)

CaLM preserves detail & lesion contrast while reducing overall image noise, and keeps workflow simple & fast.

  • Reduces statistical noise while preventing contrast degradation.
  • The parameters for CaLM are optimized according to the scan condition and the reconstruction condition.
    • Strength can be selected. (Mild / Standard / Strong)
  • No time penalty.

CaLM reduces statistical noise while preventing contrast degradation.
