Detailed Description

template<class EventDataType>
class stir::SAFIRCListmodeInputFileFormat< EventDataType >

Class for reading SAFIR coincidence listmode data.

It reads a parameter file, which refers to

• optional crystal map containing the mapping between detector index triple and cartesian coordinates of the crystal surfaces (see DetectorCoordinateMap)
• the binary data file with the coincidence listmode data in SAFIR format (see CListModeDataSAFIR)
• a template projection data file, which defines the scanner

If the map is not defined, the scanner detectors will be used. Otherwise, the nearest LOR of the scanner will be selected for each event.

An example of such a parameter file would be

CListModeDataSAFIR Parameters:=
        listmode data filename:= listmode_input.clm.safir
        template projection data filename:= <projdata-filename>
; optional map specifying the actual location of the crystals
        crystal map filename:= crystal_map.txt
        ; optional random displacement of the LOR end-points in mm (only used of a map is present)
LOR randomization (Gaussian) sigma:=0
END CListModeDataSAFIR Parameters:=

The first 32 bytes of the binary file are interpreted as file signature and matched against the strings "MUPET CListModeData\0", "SAFIR CListModeData\0" and "NeuroLF CListModeData\0". If either is successfull, the class claims it can read the file format. The rest of the file is read as records as specified as template parameter, e.g. CListRecordSAFIR.

Member Function Documentation

read_from_file() [1/2]

template<class EventDataType >

std::unique_ptr<data_type> stir::SAFIRCListmodeInputFileFormat< EventDataType >::read_from_file ( std::istream &  input ) const

inlineoverridevirtual

read data from a stream

This function should throw an exception if the read fails.

Warning

This member throws for most implementations. Use a filename instead.

Implements stir::InputFileFormat< ListModeData >.

References stir::error().

read_from_file() [2/2]

template<class EventDataType >

std::unique_ptr<data_type> stir::SAFIRCListmodeInputFileFormat< EventDataType >::read_from_file ( const std::string &  filename ) const

inlineoverridevirtual

read data from a filename

This function should throw an exception if the read fails.

Default implementation used open_read_binary and read_from_file(std::istream&).

Reimplemented from stir::InputFileFormat< ListModeData >.

References stir::info().

post_processing()

template<class EventDataType >

bool stir::SAFIRCListmodeInputFileFormat< EventDataType >::post_processing ( )

inlineoverrideprotectedvirtual

This will be called at the end of the parsing.

Returns

false if everything OK, true if not

Reimplemented from stir::ParsingObject.
