Hi Jeff

Re DICOM

Parsing a DICOM file is not that hard but it is somewhat more involved than parsing HL7 files in that:

there are options as to how it is encoded

it supports binary data

you have to read the lengths of data elements to determine where the next one starts

can switch between MSB ...

Hi Jeff

I thought the following might be useful information just in case you run into a source of HL7 messages where the preferred deliniators were not used

In HL7 messaging, the separator characters are also known as the message delimiters or special encoding characters. The following are the HL7 ...

Hi Jeff

I forgot to mention that at one time you had to pay to get the HL7 specification but now it can be downloaded free of charge.

BTW the DICOM specification has always been available for download free of charge.

Hi Jeff

In production I am creating HL7 messages not reading them and extracting data. However as part of developing my code I wanted to test it before inflicting my messages on anyone so I wrote some code to read test messages that my software wrote and extract the original data out of them. I'll ...

Hi Guys,

About DICOM/HL7 images, Did you have already looked at this http://www.merge.com/Solutions/Toolkits.aspx ?

Hi Doug,

For HL7, I looking to parse the incoming HL7 message so I can populate my database with the patient info etc..

For DICOM, what I would like to do is take whatever info comes out of a DICOM enabled medical device and again, populate my database.
The DICOM side of things is not too urgent ...

Hi Jeff

Re HL7

I am sending HL7 messages in production use. Currently only 2 message types - from memory (will check when back in at work) REF and LAB2. In practice I found that local (Australian) implementations whilst supposedly following the standards had their own variations. Happy to share ...

Hi Doug,

Did you ever end up creating your code to read/write HL7 messages?
If so, would you be willing to share your code?

Also, same question for DICOM

Hi to all,
I have some old sistems in FW and Clipper and for several resons, I did not convert them to FWH.
Instead, I wrote routines to access internet data in FWH and intended to call them with WaitRun() from the FW Clipper sistems.
The I learned the WaitRun in FW Clipper uses 100% cpu time and ...

Hi Ivan

The HL7 message that I have to generate is a REF message (a referral). You probably need a different message although some of the segments are probably common.

I don't have the HL7 specification (you have to purchase it and it isn't cheap) but I do have sufficient information to generate ...

Hi Doug

At first I think I need to generate an HL7 file to send data automatically to medical devices. This information has to be incorporated to their task lists. Then, after the medical study be done, the DICOM file generated (by de medical machine) is sent to the DICOM file server (PACS).

The ...

Hi Ivan

What is the format of file you need to generate - HL7 or DICOM?

An HL7 file will begin with "MSH" (for Message Header) and if it is using the standard separator will contain lots of "|" characters and should be all text.

A DICOM file will begin with "DICOM " (from memory) and will contain ...

Hi xProgrammer (do not know your name)

I'm just learning about this.

For now what I need (i think) is this part of your answer: "For this application it just needs to be written as a file and dumped into a designated folder for another application to pick up and process..."

Basically I must ...

Hi Ivan

I haven't touched my DICOM code for some time now as other projects took priority. When I last used it I had it correctly requesting a session, processing the reply, requesting a session close and getting the acknowledgment.

I wasn't getting a response to a request for a list of scans so ...

Hi
Are there any developments regarding this topic?

I need to develop an interface between my patient administration software and equipment based on DICOM.
The mechanism appears to be using HL7 but do not know how to deploy.
The idea is to export the data from patients directly to DICOM equipment ...
