Detailed Description

Dynamic projection data.

Somewhat preliminary

Todo:

Move read_from_file, write_to_ecat7 to usual registry methods

Interfile support currently doesn't set start_time_in_secs_since_1970

Member Function Documentation

◆ get_start_time_in_secs_since_1970()

const double stir::DynamicProjData::get_start_time_in_secs_since_1970 ( ) const

Return time of start of scan.

Returns: the time in seconds since 1 Jan 1970 00:00 UTC, i.e. independent of your local time zone.

Note that the return type is a double. This allows for enough accuracy for a long time to come. It also means that the start time can have fractional seconds.

The time frame definitions should be relative to this time.
