For user of EchoPAC PC Software Only:
It is possible in Windows to start several instances of
EchoPAC PC. I.e. the same application is launched more than
once. It is strongly recommended not to do this, as this will
cause several functions and features in EchoPAC PC not to work
properly. Only ONE instance of EchoPAC PC should be running.

Searching a Patient record
When the login procedure is completed, the Search/Create
patient window is displayed (see Figure 2-1).
About dataflow
Refer to page 311
for further information on connectivity
setup.
EchoPAC PC can
be configured to
generate patient ID.
The automatic
searching tool displaying matching
patient information
in the Patient list
can be turned off.
The connectivity on EchoPAC PC is based on the dataflow
concept. Each dataflow defines the transfer of patient
information from an input source to the unit, and from the unit to
an output source. Patient information can include demographic
data and images, as well as reports and Measurement and
Analysis data. A dataflow is a set of pre-configured services.
When beginning a search, the user selects a pre-configured
dataflow (see page 311 about connectivity) that will
automatically customize EchoPAC PC to work according to the
services associated to the dataflow and search in the archive
associated.
To find a patient record
1. Type the patient Last Name, and/or ID.
When default configured, EchoPAC PC automatically
searches to see if the patient is already in the database.
The result of this search is displayed in the Patient list field.
2. If necessary, select another dataflow to search in other
databases.
3. In the Patient list field, Double-click the desired patient
record (or click once on the patient record and press Select
Patient)
Or
Press [+] in front of the actual patient record and select the
desired examination.
The Examination List window is displayed (see
Figure 2-2).
In a network environment, if the user tries to open a patient
record or an examination that is already opened by another user,
CAUTION
EchoPAC PC User's Manual 13

a warning message is displayed. Do NOT attempt to open the
study that is already opened by another user.
Patient record management
1. Press one of the headings to sort the list
accordingly.
2. Select new archive and other pre-defined
services
3. The system can be configured to display the
Advanced search tool as default (see page 322)
The Search/Create patient window may be slightly different depending on the Dataflow selected.

Patient record management
Editing demographic data
If you modify the Patient ID, Last name, First name or Date of
birth on a patient in the archive, be aware that the contents of the
WARNING
CAUTION
archived images for that patient is not updated. If the images are
still in the buffer and not yet archived, the image files are updated
if you modify any patient information, but not if the images are
archived. So if any of these images are later on exported to
DICOM media or DICOM server, they will still contain the original
patient information, as it was before you did the modification in
the archive. The system does not alter the contents of the image
files at all when doing DICOM export.
The demographic data for a selected patient record can be
edited from the Patient Information window.
Do NOT use '\' or '^' in patient information fields, as these
characters might cause problems with some DICOM devices.
1. Select a patient record (see page 13) and press Patient
Info in the Examination List window (see Figure 2-2).
The Patient information window is displayed (see
Figure 2-5).
2. Edit the information using the keyboard or by choosing a
new selection from the drop-down menus.
Select the patient information category to enter application
specific patient information (Displayed when the button
More is depressed, see Figure 2-5.).
