Abstract:
Medical image diagnosis processes with stereoscopic depth by 3D display have not been developed widely
yet and remain understudied Many stereoscopic displays require glasses that are inappropriate for use in
clinical diagnosis/explanation/operating processes in hospitals. An eye-tracking based glasses-free three-dimensional
autostereoscopic display monitor system has been developed, and its feasibility for medical 3D
images was investigated, as a cardiac CT 3D navigator. Our autostereoscopic system uses slit-barrier with
BLU, and it is combined with our vision-based eye tracking system to display 3D images. Dynamic light field
rendering technique is applied with the 3D coordinates calculated by the eye-tracker, in order to provide a
single viewer the best 3D images with less x-talk. To investigate the feasibility of our autostereoscopic system,
3D volume was rendered from 3D coronary CTA images (512 by 512 by 400). One expert reader identified
the three main artery structure
s (LAD, LCX and RCA) in shorter time than existing 2D display. The reader
did not report any eye fatigue or discomfort. In conclusion, we proposed a 3D cardiac CT navigator system
with a new glasses-free 3D autostereoscopy, which may improve diagnosis accuracy and fasten diagnosis
process.
