Technical Limits of Applicability

Operating Systems

 

OnyxCeph³™ can be applied on computers equipped with a maintained Windows™ operating system.

 

 

Installation

 

For installation of OnyxCeph³™ server and workstation the requirements described under System Requirements have to be considered.  The setup program for the installation is provided exclusively as download.  Installation can also be executed from other data mediums if the setup was copied there. In any case the program OnyxCDMenu in the main path of the installation folder, that allows calling the respective functions, can be executed.

 

Installing the software is effected in two separate steps: (i) installation of system environment and database on the computer to be used as server and (ii) setup of the workstations on the same or further computers in the network.

 

Both, server and client installation requires administrator privileges. Setting up of local or network clients requires a completed server installation and running the SQL database server OnyxDBServer.exe at the server PC as service (recommended) or as program.  To perform the client installation the program OnyxClientSetup.exe has to be executed at the client PC.  It can be started eithe from a data drive or from the database server's folder "Install" on the server PC. If OnyxCeph³™ is to be used at several workstations in the network, the client installation has to be separately executed for each of them. Detailed installation instruction is available in topic Installation.

 

 

Network and Access Rights

 

The local application can be connected to the network database in different ways. It is recommended to use the pre-set standard connection via internet protocol (TCP/IP).  Separate sharing of directories is not necessary.

 

Data transport between application and database is effected via port address 16300 (Standard).  This port address must not be blocked by local security settings.  It may be changed the program environment requires that.  In case of questions, please, contact the support.

 

 

Data Formats

 

OnyxCeph³™ can read and process image records of different file types and file contents (see table).  If required, the list of accepted formats is upgraded.  All imported records are stored in the OnyxCeph³™ image database in JPG (2D) or II3 (3D) format.  As per the HIPPA specifications and independently of image type-specific settings concerning size and orientation the conformity of the original image data changed.

 

All imported 3D-Data are internally saved in ii3 file format. In case of surface data, during the import process, several topological corrections and improvements can be applied but also operations like e.g. clipping, cutting, smoothing, closing holes, remove bridges etc.

 

Volume data being transformed into surface data during import represents a specific characteristic.  The rendering processes used reproduce the dimensional model as polygonal surface model that can be used for measuring purposes so that quick and meaningful presentation as well as effective storage of the records becomes possible.  Any model can be repeatedly rendered in order to detect different material junctions.

 

Owing to the fact that depending on the type and functioning of the image source the signal intensity (gray scale value) reproduced in the volumetric element (Voxel) cannot unambiguously attributed to the X-radiation's attenuation coefficient and the radiographed tissue the morphological information enclosed in the gray scale distribution may provide additional hints for evaluation (e.g. cephalometry) and further processing (e.g. implant planning).  For this reason a volumetric model is stored as a component of the II3 record when the volumetric record is rendered.  The spacial resolution can be specified depending on the respective record's specifics.

 

The export of image data is primarily offered in the DICOM format specified by law. The export is also possible in other open formats.

 

 

Data Volume and Transfer Rates

 

Depending on the average size of the image data stored at the server, an adequate data transfer rate to the client is a basic requirement for satisfying work with OnyxCeph³™.  In case of regular use of very large data volumes (e.g. records with several surfaces rendered from large CBCT volumes) the use of an additional Onyx server or the setup of a stand-alone workstation may be advisable.

 

 

Interfaces

 

OnyxCeph³™ supports several interfaces for direct data exchange with third party tools.  These interfaces allow interactive exchange of patient data or images or both. Full particulars on these topic are in the Configure Interfaces chapter or in the separate technical documentation.
