Title: New tools for teleconsultations MediPAS

1
New tools for teleconsultations MediPAS

Dr. Vaidotas Marozas
Institute of Biomedical Engineering
Kaunas University of Technology

2
Objective

To develop a new affordable and integrated
software for acquisition of medical images,
analysis, teleconsultation and archiving.

3
MediPAS development method

Developed by telemedical applications group at
Kaunas University of Technology
With practical consultations from otolaryngology,
ophthalmology and pathology doctors at Kaunas
Medical University Hospital
In cooperation with Euromed Networks AB from
Stockholm
Under supervision of TietoEnator Trigon AB from
Malmo

4
Features of MediPAS software

Main features
Image acquisition
Image editing
Image processing
Review of images
Design of databases
General features
Advances features
Plug-In for Pathology
Conferencing and discussion of images

5
Acquisition of images

Is possible to acquire image from
analog video camera trough frame-grabber,
digital camera trough TWAIN software interface,
file stored on hard disc,
database (local or remote on the server).

6
Acquisition from digital camera

MediPAS using TWAIN standard interface is
compatible to most of modern digital cameras.

Standard features of TWAIN interface enables user
to control camera from MediPAS.
7
Review of images

To facilitate review of images
list of load images with thumbnails
click and drag to scroll image
left/right click or moise wheel to
ZoomIn/ZoomOut
compare side-by-side

8
Image edit

In MediPAS it is possible to
select part of the image
copy
cut
paste
rotate image.

9
Image processing

Basic image processing in MediPAS
brightness
contrast
colour saturation
undo
return to original image.

10
Working with databases

MediPAS supports local (MS Access) and remote (MS
SQL Server) databases.
In databases is possible to store images and
related text information.
User can easily design database forms and tables
him-self.
It is very easy to store image into database -
drag and drop.

11
General features

Languages English and Lithuanian
Selection of toolbars Main, Image, Annotations,
Conferenc, Database)
Image information
Full Screen.

12
Advances features Plug-Ins

There is developed solution to implement
Plug-Ins, the advanced image processing tools
according to doctors order.
We used to code image processing algorithms in
advanced software package MATLAB.
There is designed algorithm and implemented in
MediPAS as the Plug-In the tool for quantative
analysis of pathology images- Labelling Index
estimator.

13
Advances features teleconferencing

Conferencing possibilities in MediPAS
videoconferencing using software and hardware
(Zydacron) codec
sending / receiving images
discussion of image on common desk-top
synchronised drawing on the same image from both
sites
storing drawings and notes into database.

14
Peripherals needed for conferencing
Web camera with USB interface Headset with
microphone Internet connection

Conclusions

MediPAS software assists doctors in
Acquiring of digital images
Reviewing and management of images
Organising of visual and text data in databases
for further research
Automatic quantitative analysis of images using
specialised Plug-Ins
WEB service for pathology assist doctors in
Making quantative assesment of pathology images
Releases doctors from instalation and maintanence
troubles
Easy to upgrade.

27
Conclusions

MediPAS software enables cheap and simple
communications on medical expertise network to
consult complicated interpretation of pathology
images.
We hope that MediPAS software will contribute to
mutual collaboration on pathology network.
