Philips has introduced its Astonish TF Time-of-Flight (TOF) technology into its new budget PET/CT scanner, the TruFlight Select, and will be making TOF a standard on the company’s entire PET line. 
By using intelligent timing, Astonish TF pinpoints the location of events with greater precision, leading to what the company claims is an up to 30% greater contrast resolution compared with non-TOF equipped systems.
From the announcement:
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.
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.
