A cortical visuomotor network, comprising the medial intraparietal sulcus (mIPS) and the dorsal premotor area (PMd), encodes the sensorimotor transformations required for the on-line control of reaching movements. How information is transmitted between these two regions and which pathways are involved, are less clear. Here, we use a multimodal approach(More)
Voreen is an open source volume rendering engine which allows interactive visualization of volumetric data sets with high flexibility when integrating new visualization techniques [Meyer-Spradow et al. 2009]. It is designed with minimal overhead, so that, even for difficult processing networks, high rendering speeds can be achieved. While Voreen is(More)
This paper presents an optimized, robust inverse kinematics solution in a closed form for redundant manipulators with seven degrees of freedom and zero link offsets like the KUKA LBR iiwa lightweight robot. The computation allows for full range elbow self-motion manifold control, defined by an intuitive angle parameter. Furthermore, by using common(More)
PURPOSE Advances in radiation therapy delivery systems have enabled motion compensated SBRT of the prostate. A remaining challenge is the integration of fast, non-ionizing volumetric imaging. Recently, robotic ultrasound has been proposed as an intra-fraction image modality. We study the impact of integrating a light-weight robotic arm carrying an(More)
This paper presents a method to solve - in real time - the three dimensional workspace generation problem for arbitrary serial manipulators. Our approach is based on Monte Carlo simulation, to process a high number of forward kinematics with randomly chosen joint values. This results in an asymptotic coverage of the reachable workspace. Additionally,(More)
This paper presents a detailed dexterity analysis of three different kinematics, comparing six-DoF with seven-DoF robots. The KUKA LBR iiwa 7 lightweight robot represents the seven-DoF kinematics, while the KUKA KR 10 is chosen as a common six-DoF robot with comparable workspace dimensions. Furthermore, the LBR iiwa is simulated as a six-jointed robot to(More)
