 DICOM = Digital Imaging and Communications in Medicine. Is a
 medical standard for distributing any kind of medical image.

 flair has a capability to process the DICOM files with the use of
 the pydicom module (available as an add-on package for your OS
 distribution) and convert them to FLUKA VOXEL and/or USRBIN compatible
 files. As well convert the RTPLAN and RTDOSE to a full input
 for simulating a treatment planning.

 The interface contains a tree browser on the left side that one
 needs to fill with the appropriate DICOM files. The tree browser is
 going to classify the files based on their modality and group them
 with the same SOP UID class

 add.gif   Add  will allow you to insert DICOM files to the project
 x.gif   Will remove DICOM files from the project

 Adding DICOM files in the project
 Click on the add.gif Add button.
 The following dialog will allow you to select the files


 Select a parent directory containing the dicom files, up to a
 "Depth" nesting of subfolders.
 Warning: Do not increase a lot the depth as it can take considerable
          amount of time to scan the sub-folders.

 Dynamic Tabs
 dicom32.gif     Display information on the selected dataset

 edit32.gif     Show in a tabular text editor the dataset

 slice32.gif     Graphical dicom viewer

 voxel32.gif     Convert a CT/NM/PT scan to a voxels file

 xray32.gif     Visualize and compare RTDOSE with USRBIN and their DVH

 plan32.gif     Convert an RTPLAN to input

 Dicom Information

 Selecting tab dicom32.gif Dicom will display some generic
 information on the selected dicom dataset.
 The displayed information will depend on the selected modality.

 e.g. when selecting an RTSTRUCT it will calculated and display all
 ROIS and their respective volumes

 Dicom Editor

 Shows in a multi-list tree as text the data stored in the selected dataset.
 The Editor permits to change the value of the data and save the file.

 For easier browsing you can filter and display only the items
 matching a specific filter pattern.

 Selecting multiple datasets (Shift+Right click) on the dataset
 left-tree, the Editor will display the "common" entries of all

 Entries that are varied will be marked with a small dice-character

 With multiple selected files, changing an entry will change this
 entry to ALL selected datasets.
 Can be used to anonymize the selected datasets.

 Slice Viewer

 The viewer depending on the modality is able to show also the ROI

 Voxel Generation

 You can convert the CT scan and the associated RTSTRUCT to a voxel
 format to be read by FLUKA

 1. Hounsfield Units
 You will need to provide a file containing the mapping mapping information
 on how to convert the DICOM units (normally Hounsfield) to materials.

 This can be done by editing the table below and save it to a file.

 Click on <new> to add a new Units range

       <  Unit     specify the upper limit (+1) of the range
                   Every entry will correspond to a range from the
                   previous upper limit until the current upper

       Material    select any of the predefined FLUKA materials as
                   well the ones in the Materials input loaded before

       Optionally you can specify correction factors for the density
       and dE/dx

       Crho_min    density correction factor to be applied on the
                   lower limit of the unit range
       Crho_max    density correction factor to be applied on the
                   upper limit of the unit range

       CdEdx_rel_min  relative correction factor on dE/dx for the
                      minimum unit in the range
       CdEdx_rel_max  relative correction factor on dE/dx for the
                      maximum unit in the range

~~~~~~ - The program will sort the Unit ranges in ascending order - The first entry will correspond to all units from the minimum in all slices to the upper limit defined by the user - All units above the last entry will be assigned to the same material as the last entry and a warning will be displayed on the output window - All intermediate units within a range will be scaled linearly - dE/dx is applied relative to the correction of density (negative
in CORRFACT) 2. RTSTRUCT and Material ~~~~~~~~~~~~~~~~~~~~~~~~ This tab allows to override some structures with a fixed material e.g. Everything outside the skin convert to Vacuum grab-dicom-voxel2.gif You need to fill in the Material override table a combinatorial operation of the rois. i. select the material override, e.g. VACUUM ii. add pairs of operation operations and ROI Operation can be: + inside of the ROI - outside of the ROI Buttons ------- VOXEL Will create the voxel file Card Will insert(or update) a VOXEL card in the input with the correct coordinates of the VOXEL RTPlan creation ~~~~~~~~~~~~~~~ grab-dicom-rtplan.gif Allows the conversion of an RTPLAN dicom file to the equivalent multi-spot beam input for FLUKA. Limitations: Currently it can create the files for one fraction and it does not create the MLC structure in case of photon plans. Beam model file: Optionally you can provide a beam model file with additional information on the beam, like momentum, angular and spatial spread per beam energy. The program will create a list of SPOTBEAM, SPOTPOS, SPOTDIR, SPOTTRAN cards converted to the patient orientation system. For each Beam it will create a separate #include file with all the necessary cards. The normalization for each beam will created with a special #define variables that can be automatically used by the DVH converter and RTViewer The program will tag all cards generated with a special variable in order to be able to delete and replace in case is needed. RTViewer ~~~~~~~~ grab-dicom-rtviewer.gif is a module linked with the RTDOSE modality to allow the comparison of the planned dose vs the calculated dose from the MC. You can load any RTDOSE and any USRBIN as planned or calculated, provide the necessary normalization factor and compare the results. When an RTDOSE or a USRBIN is loaded the program will try to automatically create the DVH histograms, provided a voxels file is present.
