VistA Imaging Issues/RPC Calls

Here are some points I have learned about VistA imaging. 

TIU EXTERNAL DATA LINK (file 8925.91)
 1  0;1                .01  DOCUMENT                        <-Pntr  [RP8925']
 2  0;2                .02  IMAGE                            <-Pntr  [P2005']
 3  1;1                  1  LINKED DATA OBJECT                            [F]

 field .01 will point to a specific TIU document
 field .02 can link to an entry in the IMAGE file
 field 1 can hold the path to a fileserver (e.g. i:\images\jr042696.bmp, etc.) 
       But note: this is not where the filename is stored.  It is in the IMAGE file record.

IMAGE (file 2005) 
 Holds metadata about stored images

If there in an entry in TIU EXTERNAL DATA LINK (file #8925.91), then the corresponding document in CPRS will show a picture icon beside it.

Entry in IMAGE file will point to TIU EXTERNAL DATA LINK file, like this: 

 Here are NOTES about IMAGE file:
 PARENT GLOBAL ROOT D0 <-- contain IEN of TIU document this links to (E.G. 14321)
 PARENT DATA FILE#  <-- 8925 (for images linked to notes)
 PARENT DATA FILE IMAGE POINTER <-- should hold IEN of entry in TIU EXTERNAL DATA LINK
   used to check existence of ^TIU(8925.91,IEN,0)

Here is a sample successful Record in the IMAGE file

The main, top-level imaging menu option is: MAG SYS MENU It is locked with key: MAG SYSTEM


Note: the file IMAGING SITE PARAMETERS (2006.1) should be set up.

Here are some potentially relevant RPC calls 


MAGGADDIMAGE                   This is the RPC call used by VistA Imaging to add an image.
MAG3 CPRS TIU NOTE             Returns a list of all images for a TIU document
MAG3 TIU DATA FROM DA          Get TIU data from the TIUDA.
                               Returns Document Type, and Document Date/Time
MAG3 TIU IMAGE                 Files the TIU pointer in Imaging and the Imaging Pointer in TIU.
MAG4 ADD IMAGE                 Adds a new entry to the IMAGE File ^MAG(2005
MAG4 CP CONSULT TO TIUDA       Imaging Capture workstation calls this RPC to get a TIU IEN 
                               to attach images to.
                               This call simply calls a CP API, which accepts DFN, Consult #, 
                               Visit String (optional), Complete|Do not Complete the |transaction.
MAG4 CP GET VISITS             This RPC call simply call a CP Routine that lists visits for a patient.
                               Imaging prompts the user with this list when a Visit String
                               is needed by CP to create a Note.
MAG4 DATA FROM IMPORT QUEUE    This call returns the Array of Data from the Import Queue, 
                               given a QUEUE Number Called from Delphi and 'M'
MAG4 REMOTE IMPORT             Called from MS Windows Application.
MAG4 STATUS CALLBACK           This RPC is called from the Imaging Delphi component when
                               an image/images have been imported via the Imaging Import API
                               being developed for use by Clinical Procedures.
                               This call is used in the test version of Import API, it will be
                               replaced in the released version.  In the released version the
                               Imaging BackGround Processor will be calling the Status Callback 
                               routine of CP.

From the VistA Imaging technical manual (edited)... 

7.2.4 Further Information
Every individual object (i.e., an image, audio clip, waveform, or scanned document) 
is an entry in the Image file (2005), where the object's attributes are managed. In
addition, three auxiliary files are used:
• Object Type (2005.02)
• Network Location (2005.2)
• Parent Data (? 2005.03--PARENT DATA FILE ?)

The objects are then related to the patient's VISTA text data (medicine, surgery, 
laboratory, radiology reports or progress notes) through the use of pointers, both 
forward from the VISTA package file to the Image file, and backwards from the Image
file to the VISTA package file.

Software allows new objects to be added and displayed.
Several additional files are used by the system. These include:
• Imaging Workstations file that contains information about every workstation on the network.
• Image Histologic Stain file, and a Microscopic Objective file used by anatomic pathology.
• Imaging Site Parameters file.
