The TOF Revolution in PET CT Imaging
In the rapidly evolving landscape of oncological imaging, Philips Time-of-Flight (TOF) PET CT technology has emerged as the gold standard for molecular imaging. As India's cancer diagnostic needs grow—with an estimated 1.4 million new cancer cases annually—TOF-enabled PET CT systems are becoming essential infrastructure for major hospitals and cancer centers.
What is Time-of-Flight Technology?
Traditional PET scanners detect pairs of gamma rays emitted during positron annihilation but cannot determine the exact location of the event along the line connecting the two detectors. TOF technology measures the tiny time difference (in picoseconds) between when each photon arrives at its detector, enabling precise localization of the annihilation event.
Clinical Advantages of Philips TOF PET CT
- 70% Better Image Quality: Superior signal-to-noise ratio for detecting small lesions
- 50% Faster Scans: Reduced patient scan time from 20-25 minutes to 10-12 minutes
- 40% Lower Radiation: Achieve diagnostic quality with reduced FDG dose
- Better Lesion Detection: Improved sensitivity for lesions <10mm
Philips TOF Models Available at Sunrays
| Model | TOF Resolution | Best Application |
|---|---|---|
| Philips Gemini TF | 585 ps | Oncology, Cardiac PET |
| Philips Ingenuity TF | 502 ps | Research, Advanced Oncology |
| Philips Vereos Digital PET CT | 310 ps | Precision Oncology, Small Lesion Detection |
ROI Considerations for Indian Hospitals
A refurbished Philips TF-series PET CT from Sunrays Medical costs 50-60% less than new equipment while delivering identical clinical performance. With India's PET CT procedure volume growing at 15% annually, the payback period for a refurbished system can be as short as 2-3 years.
