IDWC file

Background

IDWC format is used for example in Imanet Hammersmith to save the regional tissue time-activity curves (TACs).

Specifications

• IDWC specification 1.0 2007-02-10

Format conversion between IDWC and DFT

Regional TAC data files can be converted from DFT to IDWC format and vice versa using dft2idwc and idwc2dft.

Note that before file format conversion you may need to remove the correction for physical decay, change the sample times from minutes to seconds, or convert the units of radioactivity using dftunit.

Support for IDWC files by in-house software in Turku

Starting in the end of year 2005, recent versions of software that have been compiled with libtpccurveio version 1.2.1 or later (you can check this by giving command line option -v to the program) can identify and read IDWC files instead of DFT files, if filename extension is *.idwc or *.idw. However, software saves TAC data always in DFT format.
