TI  - 3DVIEWNIX-AVS: a software package for the separate visualization of arteries and 
      veins in CE-MRA images.
PG  - 351-62
AB  - Our earlier study developed a computerized method, based on fuzzy connected 
      object delineation principles and algorithms, for artery and vein separation in 
      contrast enhanced Magnetic Resonance Angiography (CE-MRA) images. This paper 
      reports its current development-a software package-for routine clinical use. The 
      software package, termed 3DVIEWNIX-AVS, consists of the following major 
      operational parts: (1) converting data from DICOM3 to 3DVIEWNIX format, (2) 
      previewing slices and creating VOI and MIP Shell, (3) segmenting vessel, (4) 
      separating artery and vein, (5) shell rendering vascular structures and creating 
      animations. This package has been applied to EPIX Medical Inc's CE-MRA data 
      (AngioMark MS-325). One hundred and thirty-five original CE-MRA data sets (of 52 
      patients) from 6 hospitals have been processed. In all case studies, unified 
      parameter settings produce correct artery-vein separation. The current package is 
      running on a Pentium PC under Linux and the total computation time per study is 
      about 3 min. The strengths of this software package are (1) minimal user 
      interaction, (2) minimal anatomic knowledge requirements on human vascular 
      system, (3) clinically required speed, (4) free entry to any operational stages, 
      (5) reproducible, reliable, high quality of results, and (6) cost effective 
      computer implementation. To date, it seems to be the only software package (using 
      an image processing approach) available for artery and vein separation of the 
      human vascular system for routine use in a clinical setting.
