(Python) Base module for parsing DICOM files in the pf* family.
Project description
Quick Overview
pfdicom is primarily a base module for other, more specialized classes. It typically is never used on its own.
Overview
pfdicom in and of itself provides minimal end value. This module/class is intended to be a building block for deeper functionality. Its purpose is to probe a given directory filesystem for DICOM files and construct a tree representation (using pftree), and then, for each directory provide the means to read in a given DICOM file (using pydicom) to provide some minimal tag extraction and output file templating.
Most importantly, derived classes of this parent class can provide detailed and powerful methods to process the directories containing DICOM files, saving results to an output file tree.
Dependencies
The following dependencies are installed on your host system/python3 virtual env (they will also be automatically installed if pulled from pypi):
pfmisc (various misc modules and classes for the pf* family of objects)
pftree (create a dictionary representation of a filesystem hierarchy)
Installation
The best method of installing this script and all of its dependencies is by fetching it from PyPI
pip3 install pfdciom
Command line arguments
-I|--inputDir <inputDir>
Input DICOM directory to examine. By default, the first file in this
directory is examined for its tag information. There is an implicit
assumption that each <inputDir> contains a single DICOM series.
-i|--inputFile <inputFile>
An optional <inputFile> specified relative to the <inputDir>. If
specified, then do not perform a directory walk, but convert only
this file.
[-O|--outputDir <outputDir>]
The directory to contain all output files.
-e|--extension <DICOMextension>
An optional extension to filter the DICOM files of interest from the
<inputDir>.
[-t|--threads <numThreads>]
If specified, break the innermost analysis loop into <numThreads>
threads. Please note the following caveats:
* Only thread if you have a high CPU analysis loop. Since
most of the operations of this module will entail reading
and writing DICOM files, and since these operations are
the bulk of the execution time, adding threading will not
really help.
* Threading will change the nature of the innermost looping
across the problem domain, with the result that *all* of the
problem data will be read into memory! That means all of
DICOMs across all of the subdirs! In non-threading mode,
only DICOMs from a single directory at a time are read
and then discarded.
This flag is less applicable to this base class. It is here
to provide fall-through compatibility with derived classes.
[-x|--man]
Show full help.
[-y|--synopsis]

-v|--verbosity <level>
Set the app verbosity level.
-1: No internal output.
0: All internal output.
