Query: Localizing dexterous surgical tools in X-ray for image-based navigation   X-ray image based surgical tool navigation is fast and supplies accurate
images of deep seated structures. Typically, recovering the 6 DOF rigid pose
and deformation of tools with respect to the X-ray camera can be accurately
achieved through intensity-based 2D/3D registration of 3D images or models to
2D X-rays. However, the capture range of image-based 2D/3D registration is
inconveniently small suggesting that automatic and robust initialization
strategies are of critical importance. This manuscript describes a first step
towards leveraging semantic information of the imaged object to initialize
2D/3D registration within the capture range of image-based registration by
performing concurrent segmentation and localization of dexterous surgical tools
in X-ray images.
  We presented a learning-based strategy to simultaneously localize and segment
dexterous surgical tools in X-ray images and demonstrate promising performance
on synthetic and ex vivo data. We currently investigate methods to use semantic
information extracted by the proposed network to reliably and robustly
initialize image-based 2D/3D registration.
  While image-based 2D/3D registration has been an obvious focus of the CAI
community, robust initialization thereof (albeit critical) has largely been
neglected. This manuscript discusses learning-based retrieval of semantic
information on imaged-objects as a stepping stone for such initialization and
may therefore be of interest to the IPCAI community. Since results are still
preliminary and only focus on localization, we target the Long Abstract
category.
