Ultrasound and model based acquisition of knee morphology

Orthopedics can profit from precise patient-specific reconstructions in many ways. For example operations can be navigated, executing a pre-operative planning. This increases the reliability as well as precision of the intervention. Use cases include arthroplasty as well as osteotomy. Furthermore an analysis of the patient’s biomechanics requires the bone geometry.

State of the art techniques rely on computed tomography (CT) or magnetic resonance imaging (MRI) in order to obtain the 3-dimensional surface models. However, both techniques suffer from downsides: In case of CT, the patient as well as the clinical personal is exposed to radiation. MRI however can only visualize healing processes of the bone to a certain extent. Ultrasound in contrast allows for real-time visualization of the dynamic behavior of soft tissue like the cruciate ligaments.

At the chair for medical engineering we develop a system that allows for a precise reconstruction of the bone surface. Apart from a registration of the ultrasound images this requires the segmentation of the bone surface. Our model and data based techniques concentrate on the knee joint but are extendable to other body parts.
