Integration Overview

The MedDream DICOM Viewer ensures a prompt and reliable way to search, view, analyze and diagnose medical images, signals and video files from anywhere and on any device. Web-based DICOM Viewer is developed using responsive design, that enables medical images to be accessed not only on computers, but also on tablets, smart phones or other devices with mobile view functionality.

MedDream is FDA cleared for diagnostic use and is CE Class IIa certified as a medical device that can be used for review purposes or even primary diagnosis. Read more about MedDream certifications. 

As a diagnostic image viewer, MedDream consists of a Viewer component, which runs in a browser and does not require any installation on the client device, and a MedDream application server, which handles communication with the hospital systems (HIS/RIS/PACS/VNA and any other EMR) and prepares images for streaming to the MedDream DICOM Viewer.

MedDream uses a flexible and open integration interface for connecting to HIS and/or EMR systems primarily based on URL calls, thus allowing it to be integrated into any medical application.

The MedDream application server connectivity to the PACS can be achieved using:

  • WADO RESTful services;
  • DICOM Q/R on Study Level;
  • Direct access to the file system and database;
  • Gateway PACS plugins.

The MedDream DICOM Viewer provides not only standard image manipulation tools but also a way to read, manipulate and interpret electrocardiography (ECG) and ultrasound (US) data.

ECG manipulation tools are all presented in an innovative zoom model, which allows zooming in/out, measure and quantify the ECG data:


Measurement (mV, s). Area calculation indicating beats per minute, time, millivolt (mV, s, bpm);


QT points (RR, QT, QTc). QT interval - the RR interval is calculated as well as QT and the QTc (based on Bazett’s formula);


HR. Measure heart rate (HR) and compare its interval variance over the ECG;


QRS axis. Measure the QRS electrical heart axis;


Studies comparison. Compare of two or more ECGs.

For ultrasound data MedDream also supports these features:


VTI. Velocity Time Integral used to measure the distance which the blood was ejected over a date interval of time;


Up to 12 US studies may be opened at once.

Supported ECG devices: 

  • Mortara
  • Custo med
  • Schiller
  • GE
  • Other 12 lead DICOM ECG (Little Endian) or devices that, in conjunction with a gateway, can provide such data.

Other parties’ brand names, with ownerships belonging to Mortara Instrument, custo med GmbH, SCHILLER AG, GE Healthcare, are not authorized by, sponsored by or associated with the MedDream trademark owner.

MedDream can be used to measure the volume of a 2D image by using Simpson’s approximation rule; the 2D area spun around a selected axis to form a 3D shape and the volume is measured. This technique allows volume measurements of a heart in a 2D computed radiography image.

MedDream supports measurement of the Velocity Time Integral (VTI) on ultrasound (US) studies that can quantify the trace of the Doppler flow profile.
