Conquest as an automatic image-converter?

in your dicom.ini file you can add an export converter:
Export converter:

# Make directory using bat script# Convert images and add them in the correct directory##################################Exportconverters  = 2ExportConverter0 = "mkdcmdir.bat %i"ExportConverter1 = "dcmj2pnm.exe +oj +Wm --scale-x-size 600 %f D:\www\temp\%i\%b.jpg"

mkdcmdir.bat file:

@ECHO OFF
REM %1 = name of the directory to create


REM # CREATE DIRECTORY TO HOLD JPG IMAGES IN WWW FOLDER
mkdir D:\www\temp\%1
@ECHO ON

this should do the trick for you. - just hollar if you need any help.

With exportconverters you can surely do this! Just slightly edited the post.

hello
i am interested in this functionality but I wonder what are the variables %i , %f, etc.
would it be possible to create the JPEG in a folder with the patient name and a subfolder with the date?
thanks

Hi,

Sure, you can use a number of predefined tags like %f (filename) and %i (patient ID) in the converter string, but also any entry in the DICOM header (%V0010,0010), this is the patient name. Just look the syntax up in the manual.

Marcel

Thank you very much !
I'll have a look

I'm not at work I can't try it for now but do you have a sample file of a Linux bash script?
I fear there will be a problem with the spaces when creating a folder with the patients name.
will this command work?
mkdir /home/jpegimages/$1
$1 being the first argument containing %V0010,0010 (patname)

It's out of topic but if anybody know...

Probably you can use quotes around the directory name.
Marcel

Hum,
Is ther something wrong in my syntax?

What i tried:
In dicom.ini:

ExportConverters = 2ExportConverter0 = ./mkdcmdir.sh '%V0010,0010' '/%V0008,0020'ExportConverter1 = dcmj2pnm +oj +Wm +Sxv 1024 %f /home/dicom/jpeg/%V0010,0010/%V0008,0020/%b.jpg

In mkdcmdir.sh

#!/bin/bashcd /home/dicom/jpegmkdir "$1"cd "$1"mkdir "$2"cd "$2"mkdir "$3"cd "$3"

Note that if ina shell i run

./mkdcmdir.sh 'name firstname' 'year month day'

it works.

You don't need a separate script to make the directories. mkdir with the switch --parents will make necessary parent directories so this should do what you want

ExportConverters = 2
ExportConverter0 = mkdir --parents "/home/dicom/jpeg/%V0010,0010/%V0008,0020"
ExportConverter1 = dcmj2pnm +oj +Wm +Sxv 1024 %f "/home/dicom/jpeg/%V0010,0010/%V0008,0020/%b.jpg"

Just perfect!
Thank you very much!!!!!
I hope it will help other people

Hi,

Im trying to do the same thing with windows but i cant seem to get any jpeg images
my dicom ini is as follows

ExportConverters = 2
ExportConverter0 = mkdir "R:\LOCALPACS\Data\jpeg\%V0010,0010\%V0020,0011"
ExportConverter1 = dcmj2pnm +oj +Wm +a %f "R:\LOCALPACS\Data\jpeg\%V0010,0010\%V0020,0011\%b.jpg"

the server log shows
[CONQUESTSRV2] Exportconverter0.0 executes: mkdir "R:\PACS_SERVERS\LOCALPACS_MR_2\Data\jpeg\DandyWalker\4"
[CONQUESTSRV2] Exportconverter1.0 executes: dcmj2pnm +oj +Wm +a R:\LOCALPACS\data\0110817\1.3.12.2.1107.5.1.4.54546.30000006060500411659300011191_0004_000084_12384099970053.dcm "R:\PACS_SERVERS\LOCALPACS_MR_2\Data\jpeg\DandyWalker\4\1.3.12.2.1107.5.1.4.54546.30000006060500411659300011191_0004_000084_12384099970053.jpg"

but when i look at the directory it only shows the dicom image files. There are no jpeg files

anyone with an idea what going on?

ajg

Just a few correction the dicom ini is

ExportConverters = 1
ExportConverter0 = cmd /c mkdir "R:\LOCALPACS\Data\jpeg\%V0010,0010\%V0020,0011"; dcmj2pnm +oj +Wm +a %f "R:\LOCALPACS\Data\jpeg\%V0010,0010\%V0020,0011\%b.jpg"

The directories are properly created but there are no jpeg images

We're having the same problem...

We'd like to de-identify the images, then export as standard jpgs to a folder named for the accession number.

Any ideas?

Hi,

This is a typical de-identification routine for 1.4.15alpha (all on one line):

ImportConverter0 = newuids; set 0010,0010 to ""; set 0010,0020 to "%A0010,0020_%A0010,0030"; set 0010,0030 to "%V0010,0030[0,3]0101"; set 0010,1040 to ""; set 0010,2154 to ""; set 0032,4000 to ""; set 0032,1030 to ""; set 0033,100e to ""

The accession number can be accessed with %V0008,0050

So combining the two should be doable.

Marcel

We're good with the de-identify process. We're just unable to get something similar to the process below to work. A folder is created, but no jpegs live there...

So, in essence, we'd like to be able to send studies to a conquest instance, change the patient name to the accession number, then output images of that accession number as standard jpegs to a folder of that name (accession number not patientname)

Quote from jasonslan

in your dicom.ini file you can add an export converter:
Export converter:

Code

# Make directory using bat script# Convert images and add them in the correct directory##################################Exportconverters  = 2ExportConverter0 = "mkdcmdir.bat %i"ExportConverter1 = "dcmj2pnm.exe +oj +Wm --scale-x-size 600 %f D:\www\temp\%i\%b.jpg"

mkdcmdir.bat file:

Code

@ECHO OFF
REM %1 = name of the directory to create


REM # CREATE DIRECTORY TO HOLD JPG IMAGES IN WWW FOLDER
mkdir D:\www\temp\%1
@ECHO ON

this should do the trick for you. - just hollar if you need any help.

Hi,

I believe placing an export converter in "" is wrong. "" are used around strings inside the export converter.

For debugging, if you precede your exportconverter1 with a nop (no operation), the log will show what line it wanted to execute....

ExportConverter1 = nop dcmj2pnm.exe +oj +Wm --scale-x-size 600 %f D:\www\temp\%i\%b.jpg

In 1.4.15alpha, there is also a convert to jpg dgate command:

Try

ExportConverter1 = dgate.exe "--convert_to_jpg:%f,600,D:\www\temp\%i\%b.jpg,//0"

This should print frame 0 with automatic level and window.

Marcel

Marcel,

Thanks again, that worked great. We made some changes as shown below. When we set %i, it used the patient's real ID. We therefore used import converters to change the name field to the accession number, then used that as folder name for the jpegs. We wanted larger images, so we experimented with the scale-x-size setting. Setting it to 5000 gives us 600K-600K images which we think will be okay. How does that setting work? What if we wanted larger jpegs?

ExportConverter1 = nop dcmj2pnm.exe +oj +Wm --scale-x-size 5000 %f D:\retinal\%V0010,0010\%b.jpg

Thanks again!

Mike.

Hi,

You will have to look that up for dcmj2pnm wich is not my product. For dgate --convert_to_jpg, the software does an integral (1, 2, 3, ..) downsize to below the specified size for the horizontal axis.
