Cedara Software, a Merge Healthcare company, highlighted at RSNA 2006 several new applications for deformable registration and image fusion such as PET/CT image fusion, lung SPECT/CT image fusion, and MRI/SPECT image fusion for the brain. The company also demonstrated its new C4 integration platform, which is a system that allows OEM companies to tightly integrate applications into their existing technologies.
The company said the works-in-progress applications have been applied to neurology, oncology, radiology and other clinical disciplines for the analysis of lung cancer, emphysema, pulmonary embolisms, general neural conditions, Alzheimer's, stroke, brain cancer and more. Cedara said its deformable registration solution for PET/CT imaging has obtained FDA 510(k) clearance.
Rigid registration provides one method of aligning images by magnifying, rotating or translating one image to match another. Non-rigid or deformable registration is a method that can warp, shear, bend and otherwise transform an image to gain a correspondence, Cedara said. For example, breathing causes a patient's lungs to be shaped differently between imaging sessions; in this instance, a select anatomical region changes its volume and shape in a different manner from the rigid rib cage that surrounds it. In order to align these images, a complex warping transformation is required.
Cedara also introduced a new development platform named C4 (Cedara Clinical Control Center) that is designed for OEM/VARs to further unite image and information management in the healthcare industry. The C4 platform allows clinical applications and plug-ins to be tightly integrated into a single workstation, sharing system resources. Operating through a single patient study list, each clinical application can be launched manually or automatically based on user preferences. While C4 can be used to quickly integrate clinical applications into any information system, it was demonstrated at RSNA with Cedara’s web enabled PACS system Cedara I-Reach, a diagnostic information system Cedara aXigate, and in a standalone capacity.
According to Cedara, the clinical needs addressed by C4 currently include breast imaging, PET/CT imaging, orthopaedic planning, virtual colonoscopy, calcium scoring, oncology therapy response and lung nodule analysis.
