Sample text

The speed of light is very fast (30 cm/ns), but a bore diameter of 90 cm means that the difference in arrival times can be as large as 3 nanoseconds. Also, there are statistical fluctuations in the detection process of the gamma ray, and this leads to an additional uncertainty in the measurement of the arrival time. In total, the coincidence timing window is usually set to be 5 to 10 ns. The width of the coincidence window is set large enough to include any two photons that are truly from the same annihilation event—a so-called true event.

The accuracy with which this can be done is related to the energy resolution of the system. The energy resolution de- pends on the number of light photons produced and consequently on the energy of the gamma ray and the type of scintillation crystal used (its light output). TYPES OF EVENTS The signals collected with a PET camera can be categorized into one of several types. A single refers to the detection of a photon whose measured energy falls within the photopeak energy window. The photopeak energy window is wide compared to single-photon imaging, typically 400 to 600 keV.

There is a trade-off between noise reduction and image resolution, as both are in the high-frequency domain. All events or counts collected are represented in the frequency graphics. Applying a low-pass filter to the collected data will remove high-frequency data, reducing noise and image resolution (Figure 1-16). The low-frequency data will have a higher weighting factor, and the resulting image will be too smooth, lacking highresolution details. High-pass filtering, similar to the application of the ramp filter, reduces blur in the image by retaining high-frequency data.
