Digital Data Capture Interface captures the data from the ‘printer end” of the printer cable of the instrument and sends it to computer memory.
This digitally captured data is converted to a PDF document or a set of JPEG images, based on
the contents of data. Final results are available to the integrated Acquisition Modality Importer
Software for further action.
Acquisition Modality Importer Software:
This software simulates acquisition modality interface for the instrument and communicates with
the information system and DICOM archive in a DICOM network. The software allows operator
to retrieve patient demographics and ordered procedures from the information system through a
worklist query/retrieve protocol.
Operator selects a workitem for a patient from the retrieved worklist or creates a new patient
entry in the worklist for performing a procedure. Comprehensive information for the selected
workitem is displayed, including procedure protocols and any instructions from the doctor to
guide the operator. When the operator accepts a workitem for performing a procedure, software
sends a message to the information system that procedure has started. Operator performs the
procedure normally, using the instrument.
After completing the procedure, operator prints the results normally as per standard operating
procedure of the instrument. Results from the instrument, instead of physically printing, appear
as DICOM encapsulated PDF document or SC image set on the user interface of the computer
display screen.
At this stage, operator may further add his/her observations and any other data on materials
consumed for billing purposes, and then press a “button” to communicate completion of
workitem. Software takes the following further actions automatically:
1. Make DICOM object(s) of the results and transfer to image archive for storage
2. Seek commitment for safe storage of DICOM object(s) from image archive.
3. Send “workitem completed” message to the information system
4. Save DICOM object(s) in its local storage.
Types of printer ports:
TAMI can be used for instruments with many types of printer ports. Its implementation depends
upon printing facility of the instrument in terms of physical printer port used and the way the
result data is structured for printing.
TAMI can be configured to capture data from physical printer ports such as “Parallel”,
“Serial”, “Ethernet”, etc. Captured data is converted into a PDF document in the same format and appearance as it
would have physically printed.
If software can identify images and fields of data items in the captured data, TAMI can be
configured to create ophthalmic specific DICOM objects or DICOM SC objects instead of
DICOM encapsulated PDF objects.
Instruments with display only capability:
For instruments that only display the results, and have no printing facility, TAMI provides an
interface for operator to enter the results through keyboard of the computer. For such
instruments, TAMI always creates ophthalmic specific DICOM objects.
