Abstract
Systems and methods are disclosed in which a parallel kinematic robotic manipulator facilitates alignment of an insertable medical instrument according to an intraprocedurally-defined trajectory that is based on the identification, within volumetric image data, of a target location or region associated with a diagnostic procedure or therapeutic intervention. In some example implementations, a patient support is employed to provide access to an anatomical region, such as a pelvic region, and facilitate the placement of the parallel kinematic robotic manipulator in close proximity to the anatomical region, providing a compact configuration that enables intraprocedural imaging for target localization and registration of the frame of reference of the volumetric images with a frame of reference of the parallel kinematic robotic manipulator. In some example embodiments, the robotic system employs includes slider-based prismatically- driven parallel kinematic robotic manipulator, having a set of rails angled inwardly, with at least two carriages per rail.
