LOGIS development team works together with Austrian company «Kretztechnik», the world leader in medical 3D ultrasound, under development of software for their world's first real-time 3D ultrasound system V730. Since July of 2001, «Kretztechnik» became subsidiary company of General Electric Medical Systems.
	LOGIS development team participated in following «Kretztechnik's» projects: Development of «Stress Echo Diagnostic Module». Development of device driver for hardware accelerator that provides high-speed medical ultrasound data transfer. Software optimization and performance boosting solutions for real time imaging using «Direct Draw». Development of software engine that controls color touch panel. Enhancing visual presentation of touch panel objects. Software interface between ultrasound system and video recorder. System maintenance software. Online service solution that assist serviceman to get system information anytime and from anywhere. It records system events into local database and provides access to information for remote service offices with web interface. HL7 communication software development.

As a part of collaboration with «Kretztechnik» company we developed mathematical software for processing of echograms acquired as result of ultrasound medical investigation and represented as 3D or 4D digital voxel graphics. Our task was development of the modules that carried out the following functions:

• Echogram spectral analysis for heartbeat frequency extracting.
• Echogram filtering for destructive noise removing.
• Phase echogram processing.
• Echogram phase interpolation for getting smooth animation.
• Echogram rearrangement.
• Electrocardiogram analysis: QRS complexes detection for phase identification of echogram segments. About detection technology you can read in the sample «ECG Processing».
