Abstract:
Based on photon counting mode,a multi-channel continuous-wave(CW) diffuse optical tomography(DOT) system is designed for galactophore inspection.For the acquisition of dynamic information,the instrument adopts the non-intermittent counters to achieve the function of width-adjustable moving gate.The width of the moving gate can be changed from 50 microseconds to about 10 seconds,and correspondingly the total temporal span of the measurement ranges from several milliseconds to tens seconds,depending on the preset gate number.The data transfer as well as the system control is through the universal serial bus(USB) 2.0 technique,with which the system can readily extended for a variety of applications requiring different spatial resolution.
