    Combining Mobile Devices and Workstations for the Reading of Medical Images
    (Mensch & Computer 2012 – Workshopband: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Ritter, Felix; Harz, Markus; Al Issawi, Jumana; Benten, Simon; Schilling, Kathy
    We propose a new concept for the combination of mobile multi-touch devices and diagnostic reading workstations to provide a workstation-grade reading experience of medical images with mobile devices. The patient-centric, workflow-oriented design links a mobile device with dedicated diagnostic monitors and adapts the behavior and the presented content of the mobile device depending on the location and access permission level of the user. The design is based on a breast MRI reading system, exploring the suitability of touch interaction for diagnostic reading of MRI patient cases. In this article we discuss the benefits for the radiologist as well as possible challenges and briefly describe the results of an informal evaluation we conducted with radiologists.

    Real-time breast deformation using non-linear tissue properties
    (INFORMATIK 2011 – Informatik schafft Communities, 2011) Harz, Markus; Georgii, Joachim; Schilling, Kathy; Hahn, Horst
    Localization of target structures in open surgical breast procedures mostly rely on localization wires that give coarse orientation hints together with a set of radiological images to convey the extent and location. Patient positioning, however, is different for image acquisition and surgery. We propose to simulate the breast deformation between these positions to track and visualize the target position. To date no sufficiently fast and accurate methods have been proposed for that purpose, which is caused by the computational expensiveness caused by the non-linear behavior of the material. In contrast, the FEM-based simulation framework employed in our work allows for an online update of material attributes, in particular the per-element elastic modulus, which affects the reaction to forces. Fast breast deformation simulation is thereby for the first time amenable to improve accuracy and confidence of breast surgeons compared to the de-facto standard techniques for localization of target structures.
