hlut | file / import() list num() debug
export() delete eqvpathlength()
read display
write inspect
Purpose
Handles input, output and interpolation of a Hounsfield Look-Up table (HLUT).
Only one single table is supported.
Parameters
- file
-
Name of a file which contains a HLUT.
May contain environment variables.
Usually Hounsfield Look-Up tables have the extension
.hlut
- import()
-
Not yet implemented.
- export(fmt)
-
Exports current HLUT in some other format,
at present only
gd
is implemented to export for the

- write
-
Write the current HLUT to file
- list

- delete
-
Deletes the loaded HLUT.
- display
-
Displays the current HLUT. Not yet implemented.
- inspect
-
Show some internal info about the current HLUT.
- num(hf)
-
Interpolate water-equivalent path length for the
Hounsfield number
hf
.
- eqvpathlength(len)
-
Interpolate the Hounsfield number for the
water-equivalent path length
len
.
- debug
-
Debug switch. Lots of output!
Remark
none
Examples
-
hlut $TRIP98/DATA/*.hlut /read
Reads all files in the directory "$TRIP98/DATA" with the extension
".hlut" and interpretes them as HLUTs. The last one read will
replace all previous ones and become the currently loaded table.
-
hlut / num(-41)
hlut / eqv(1)
First interpolate the equivalent path length for the CT number -41,
then the CT number for equivalent path length 1.
