1 Scope This international standard specifies the format of binary list-mode data at the output of digital data acquisition devices used for the detection and measurement of radiation. Such data acquisition devices may employ digital signal processors (DSPs) and field-programmable gate arrays (FPGAs) in combination with memory and a communication interface with a computer. This document is applicable to those data acquisition devices which are able to record and present interaction data of radiation in detectors on an event -per- event basis, with data stored in an output file or streamed to a remote computer. Such list-mode data typically contains timestamp and energy information, but may also contain digital signals or properties like rise time or sub-areas of signals computed by the DSP or FPGA from the signal samples. It is not the scope of this document to specify the communication protocol between data acquisition hardware and the instrument drivers. Instead, it specifies a standard format for the presentation of data acquired by one or more acquisition devices , to the user or user application. This document only specifies the binary formatting of data. The formatted data may be sent or stored as specified by other protocols. Also, commands to control data acquisition devices are not included in this document. This document does not put requirements on encryption or authentication of dat...
