Industry News: Definiens takes CAD into the lymph nodes


Definiens introduced its latest CAD system as a way to judge the effects of therapy on some cancer patients.

Definiens introduced its latest CAD system as a way to judge the effects of therapy on some cancer patients. Dubbed LymphExpert, the CAD technology helps detect the metastatic spread of cancer by better identifying, analyzing, and measuring volumetric changes in the size of lymph nodes. The CAD software promises to save time and make study results more consistent by automating segmentation and analysis of the nodes.
LymphExpert is brought in after a radiologist has manually detected lymph nodes in a CT image, automatically segmenting and quantifying the nodes according to established guidelines, then reconstructing a volumetric image. Definiens contends that a precise 3D picture of a lymph node's growth or shrinkage over time indicates cancer progression or remission. The Munich-based company, founded in 1986 by Nobel Laureate Gerd Binnig, develops "cognitive emulation" software that automates and quantifies challenging image analysis challenges.
