As more and more CT/MR studies are scanning with larger volume of data sets, more and more radiologists and clinician
would like using PACS WS to display and manipulate these larger data sets of images with 3D rendering features. In this
paper, we proposed a design method and implantation strategy to develop 3D image display component not only with
normal 3D display functions but also with multi-modal medical image fusion as well as compute-assisted diagnosis of
coronary heart diseases. The 3D component has been integrated into the PACS display workstation of Shanghai Huadong
Hospital, and the clinical practice showed that it is easy for radiologists and physicians to use these 3D functions such as
multi-modalities' (e.g. CT, MRI, PET, SPECT) visualization, registration and fusion, and the lesion quantitative
measurements. The users were satisfying with the rendering speeds and quality of 3D reconstruction. The advantages of
the component include low requirements for computer hardware, easy integration, reliable performance and comfortable
application experience. With this system, the radiologists and the clinicians can manipulate with 3D images easily, and
use the advanced visualization tools to facilitate their work with a PACS display workstation at any time.
