Abstract
A training system for central venous injection is proposed. Central venous
injection is a part of central venous catheter (CVC) placement. In the
CVC placement first, the needle is inserted to the vein. Then catheter
is passed along the needle. During the insertion of the needle, pneumothorax
and damages to the vein should be avoided. In proposed training system,
we can virtually perform the injection to the human which is visually and
haptically rendered. The 3D structure of human body was reconstructed from
CT images using surface rendering technique. Using stereoscopic glasses,
the life sized virtual human is displayed. Calculation method of haptic
texure which defines the hardness at human surface is proposed. We realized
virtual palpation by using haptic texture. Measurement method of the parameter
used in haptic texture model is also proposed. PHANToM haptic device is
used for recording and reproducing the sense of touch to cancel out the
error each other. We also applied the calculation method of haptic texture
to medical training system for the lumber puncture.
