Concerning the two issues of data-acquisition timings and interpolation, several dosimetric approaches exist in clinical practice, as shown in Table 4.
Industrial-type programmable controllers were used for plant control and monitoring, computers with CAMAC front-end for data acquisition and timing.
The synchronous interrupts are generated in the main loop and they are timed every 5, 10, and 80 ms by the CMT peripheral; in particular, the first timing slot is used for each data acquisition, the second timing slot is used for both data acquisition and control algorithm, and the third timing is used to manage the communication with an external device or PC.
As the data acquisition dead time is greater than the time between physical events, timing information is essential.
The paper addresses two important aspects: event-driven data acquisition and accurate timing reconstruction.
In this work we have shown that data-collection/image-acquisition timing and the method for data interpolation cannot be overlooked, since calculation of absorbed dose could lead to errors even greater than 20% and greater than those originating from activity quantification.
Amplitude information of the signals from the electronics attached to the scintillator-coupled multi-anode PMTs was collected using a data acquisition board cDAQ-91788), and the timing information was sent to a FPGA (SPARTAN3E).
To achieve real time data acquisition, we have developed a new implementation utilizing a high resolution timing module (HRMTime, SensL) to record the pulse sequence representing detected photons.
Low energy heavy ion elastic recoil detection work has been carried out in Jyväskylä since 2009 using home made timing detectors, a silicon energy detector and a timestamping data acquisition setup forming a time-of-flight energy time-of-flight energy
