This year at the SNM 2011 Annual Meeting, Royal Philips Electronics (NYSE: PHG, AEX: PHI) is announcing TruFlight Select, the first economical PET/CT system equipped with time-of-flight (TOF) technology. Although the TruFlight Select PET/CT is designed to serve the needs of facilities with budget constraints, the system is equipped with Philips’ premium TOF technology, Astonish TF. Astonish TF is the same TOF technology driving Philips’ new high-end Ingenuity TF PET/CT and PET/MR systems introduced at RSNA 2010. Astonish TF is now being standardized across the Philips PET portfolio, and Philips is offering our current TOF customers a performance upgrade to the latest version of Astonish TF.

TOF technology for positron emission tomography (PET) scanners is designed to enhance image quality by reducing image artifacts and providing higher sensitivity. The resulting images help clinicians better detect and locate lesions to increase diagnostic confidence and preserve healthy tissue during treatment. According to a recent study, TOF scans can help to improve lung and liver lesion detectability. In the study the improvement was more pronounced in heavy patients.    

Philips TOF Legacy
Having launched the first-ever commercially available TOF system, and with more than 260 original systems (GEMINI TF PET/CT) installed worldwide since 2006, Philips is leading the way in the continuous development of TOF technology. Compared to non-TOF systems, Astonish TF allows for up to 30 percent improved contrast resolution while maintaining quantitative accuracy. With 495 picosecond timing resolution on all new systems, Philips provides the fastest timing resolution of all currently available PET systems with TOF. Philips now offers TOF technology for virtually all budgets and clinical needs.
All Philips TOF PET/CT systems that have been purchased since 2006 can be upgraded to the latest version of Astonish TF for improved performance.

University of Freiburg, Germany
Prof. Wolfgang Weber of the Nuclear Medicine department at the University of Freiburg is one of the first clinicians worldwide to upgrade to latest version of Astonish TF.

“The combination of advanced TOF technology with a newer PET/CT system has contributed to significant improvements in image quality which helps us see small lesions in lymph nodes of overweight patients that may have been overlooked on non-TOF systems. We are excited to see how Astonish TF can help us in our daily practice,” commented Prof. Weber.

Vrije Universiteit (Free University) Medical Center (VUMC), in Amsterdam, The Netherlands, The Dutch Cancer Institute - Antoni van Leeuwenhoek Hospital (AVL-NKI), in Amsterdam, the Netherlands and Centre Hospital, Le Mans, France have also installed our latest Astonish TF upgrade. University Hospitals, Cleveland in Cleveland, OH is planning to upgrade its GEMINI TF 16 system and Fletcher Allen Healthcare in Burlington, VT is upgrading its GEMINI TF Big Bore. Additional installations of Ingenuity TF PET/CT, and upgrades to the latest Astonish TF technology are expected worldwide.
