4. Refinement Model

• Given an input data space X x1j, x2j,...,xnj,
  where n number of records in dataset and j is
  the dimension

16
4.Refinement Model

• Training data are iteratively modeled in II
  passes
• I. The most important attribute is further
  stretched, so the interval is magnified
• II. fuse the learning criterion for the target
  function and so we combine the local and global
  functional J(f).
• setting J(f) to be the minimising the
  mean-squared error
• the fused (mixed) J(f) is

Segmentation of vessel borders by using a
deformable cylinder
Control points are defined to make the knots
coincide with image planes
Reconstruction of the stent and the vessel wall
from an IVUS image stack

Technical extensions of the multimodal
interfacemagneto-sensor for precise 3D
positioning of the catheter to simplify the image
acquisition
Ascension Technology recently announced a medical
tracking device for transcatheter cardiovascular
intervention - 3D Guidance. The commercially
available device is a 1.3 mm sensor integrated
into the catheter
3D silicon-based magnetometer with simplified
structure and enhanced sensitivity suitable for
miniaturization of size about 1mm
