Established surgical navigation systems for pedicle screw placement have been proven to
be accurate, but still reveal limitations in registration or surgical guidance. Registration of …

During the last two decades, intra-operative ultrasound (iUS) imaging has been employed
for various surgical procedures of the spine, including spinal fusion and needle injections …

The large-scale reference system (LRS) based on multiple measuring stations is widely
used to estimate the position and orientation of the aligned components of aircraft. The …

The accurate measurement of surfaces of large aviation components is vital for the
assessment of manufacturing and assembly quality of such components. To satisfy the …

Registration is the process of computing the transformation that relates the coordinates of
corresponding points viewed in two different coordinate systems. It is one of the key …

The laser tracker is widely used in a large component measurement. In practical application,
due to the large size and complex shape, the laser tracker relocation is usually performed …

Purpose Image-guided surgery systems are limited by registration error, so practical and
effective methods to improve accuracy are necessary. A projection point-based method for …

Ultrasound (US) imaging has been widely utilized for guiding puncture procedures in spinal
interventions. However, conventional methods that confine puncture within the US plane …

In this paper, we investigate the estimation of the maximum target registration error (TRE)
magnitude of the target location while using point-based rigid registration in the image …

The rigid registration is a key step of Image Guided Surgery (IGS), and the point-pair method
is the main way used for registration. However the configuration of fiducial points has a great …
