February 9, 2016 ― HUS Medical Imaging Center in Helsinki, Finland, is undertaking the first European clinical test study of the new Carestream OnSight 3D Extremity System in pre- and post-operative cases. The study of the new cone beam computed tomography (CBCT) scanner and image reconstruction technology, applied within orthopedic imaging, will last six months and will yield valuable data for both HUS and Carestream regarding pre- and post-trauma studies involving new algorithms and advanced technology.
The Carestream extremity CBCT system (which is investigational and not available for commercial sale) captures low-dose, high-quality CT images for orthopedic medicine, delivering pristine 3-D weight-bearing images at the point of care, not otherwise possible with traditional CT.
During the research work, experienced radiologists at HUS will evaluate the image quality in bone structure, fractures and the level of metal artifacts. In addition, a medical physicist will contribute to the physical image and radiation exposure assessment.
“CBCT can be utilized as a low-dose 3-D imaging method in both pre- and post-operative diagnostics,” explained David Chan, Carestream’s global product line manager, DMS. “New iterative image reconstruction helps to mitigate image artifacts caused by metallic implants that can typically be present in many orthopaedic cases. Thus, diagnostically relevant structures such as bone fractures of different size and shape, and joint surfaces, can be evaluated more clearly. We also expect to see improvements in the characterization of soft tissue.”
Helsinki University Central Hospital is part of HUS (Helsinki-Uusimaa District), serving a population of 1.5 million people around Helsinki and the surrounding area. It includes the largest trauma imaging center in Finland, which specializes in the treatment and rehabilitation of orthopedic and trauma patients. Procedures include hand surgery, plastic surgery and neurosurgery and the imaging center performs about 90,000 operations each year.
