Larachi et al. (1996) applied their radioactive particle tracking technique to determine the time-averaged solids velocity in a three-phase fluidized bed. Techniques which are similar to CARPT, such as positron emission particle tracking and radioactive particle tracking, have been applied successfully to systems involving particulate solids. 

Powder flow patterns in wet granulation can be studied using positron emission particle tracking. Eventually, this and similar techniques can be used to validate various mathematical and statistical models of the process.

Due to the penetrating power of the emitted SllkeV gamma photons, which can pass through several millimetres of stainless steel, detection is possible from within steel reactors or process vessels. The coincident detection of photons is the principle of techniques such as Positron Emission Tomography (PET), Positron Emission Particle Tracking (PEPT), and Positron Emission Profiling (PEP), which are discussed below.
