Detailed Description

A class for storing and using a singles bucket record from a listmode file from the ECAT 8_32bit scanner.

Singles records are emitted by the scanner approximately once per second per bucket. Each record encodes the singles count for one detector bucket over the preceding interval. These are used to estimate dead time and randoms.

The PETLINK singles word has type=1, deadtimeetc=0b10 (i.e. is_other() == true in CListDataAnyECAT8_32bit), so it falls through the existing time/event checks.

Member Function Documentation

get_bucket_index()

unsigned int stir::ecat::CListSinglesECAT8_32bit::get_bucket_index ( ) const

inlineoverridevirtual

Returns the singles bucket index.

Implements stir::ListAccumulatedSingles.

get_singles_count()

float stir::ecat::CListSinglesECAT8_32bit::get_singles_count ( ) const

inlineoverridevirtual

Number of singles in this record.

The ECAT8 record stores this count divided by 8 (the 3 lowest bits are not stored), so it is scaled back here.

Implements stir::ListAccumulatedSingles.
