DxPinnacle Architecture

The DX Family combines powerful architecure with a flexible, modular design.

All members of th Dx Family share the same architecure and software organization allowing full compatibility between Dx Workstations using RISC Technology.

The Unix operating system guarantees multi-user and multi-tasking capabilities. Full programmability is achieved through high level languages such as C and C++.

Application protocols are available through a main menu bar whil display setting may be adusted through the mouse.

	Database Management
	Data is organized in a hierachical method, grouping Patient data into Exams, Studies, Acquisitions and individual Objects, as per compliance with DICOM 3.0. The Oracle Database Management System gives access to any level of information and allows reliable data handling. Selection, search, archival and retrieval becomes straightforward operations.
	Complete Processing Capabilities
	The Dx Family utilizes Dx Image, a general image processing macrolanguage designed specifically for medical image processing.

Dx image allows manipulation of images, ROI's and curves and has a number of function for filtering, arithmetic, convolution, morphology, attribute extraction, annotation and rendering operations.

	Acquisition
	Acquisition mode include : Static : up to 1024 x 1024 resolution Dynamic : 4 groups up to 256 x 256 resolution Whole body : 257 x 1024 resolution Gated : 256 x 256 up to 32 phases SPECT : 256 x 256 up to 256 steps Gated SPECT : 256 x 256 up to 256 steps ans 32 phases

Communications

Communication between the DxPinnacle and the DxMultimodality image management systems within the hospital or at a remote location may be handled by :

• Ethernet network
• Modem communications
• Media transfers
• Direct serial port linkage
• ISDN, ATM
