Dexela exhibits DexTop, its state of the art 3D mammography workstation, at the DRK conference in Berlin, 30 April – 3 May 2008

Dexela, a technology leader in the development of 3D medical imaging, will be exhibiting DexTop, its state of the art 3D mammography workstation at the DRK conference in Berlin. The annual radiology event combines both a trade fair for equipment manufacturers and a scientific conference about the latest advances in radiology.

The DexTop Mammography Workstation, which will be displayed at the Planar booth (A26), encompasses up to date computer hardware with ground up design of a mammography specific workstation. It provides high speed access to large datasets ensuring highly flexible workflow. The use of 64 bit Windows operating system allows the use of far more memory than has been available so far. The multi-core CPU technology that is fast becoming the norm has also been harnessed to provide the best hardware platform using off the shelf and inexpensive components.

The architecture of the DexTop workstation means that it can be deployed as a central base station with satellite workstations all using the same user configuration store and image data. This flexibility means that a radiologist is no longer confined to one room or to configuring more than one workstation.

The workstation offers extremely flexible hanging and workflow for today's radiologists. The emphasis on speed to screen for the image is complemented by the highly configurable hanging system in conjunction with work lists creation and definition. The radiologist can group cases together in any order and define what type of reading the work list should present itself as. This is combined with the user defined hanging associated with the work list type. The hanging system allows full use of as many screens as are available with absolute flexibility over image placement. Unlimited hangings can be defined per user. DexTop's Smart-Merge Protocol means that modality specific hanging details are combined with the current hanging to provide truly flexible hanging protocols that adapt to the data of individual cases.

Image manipulation has been thoroughly provided for. Along with the normal zoom, pan and flip DexTop provides inverted grayscale views, a magnifying cursor that provides a magnifying glass and a Hot Lamp that brings out the detail in darker areas with altering the overall contrast settings.

Images can be viewed at 1:1 data to pixel relationship, at life size and in regions making sure the radiologist sees every pixel. The handling of planar images with multiple images frames per image has been designed into the workstation from day one and as such DexTop has very fast and flexible display of these images despite their very large data sizes.

The use of linear and sigmoid curves in look-up tables and the adherence to the imaging standards with respect to VOI LUTS and the further adjustment of contrast after their application mean that DexTop provides the highest level of support for image display.

DexTop is an up to date, standards compliant, fully flexible mammography workstation already equipped to deal with the future of mammography. The product is currently awaiting 510K approval.
