9th International Workshop on Bone Densitometry, Traverse City, Michigan, 26-30 September 1992. Calcified Tissue International, 52:162, 1993.
Computer workstations are now routinely used to diagnostic image data for both viewing and image analysis. Standards of the cmputer industry provide an environment for graphic display and analysis that can be customized for specific applications. Basic principles for minimizing unnecessary graphic content on the screen, manipulating display window and level through mouse control, and selecting options through pop-up control panels provide an easy to use environment for the display of image data. These methods can facilitate a new user's ability to operate a software application, and helps focus visual attention on image data rather than miscellaneous command functions. We have used these approaches extensively in the analysis of three-dimensional bone density data. This exhibit, encorporating a computer workstation, will demonstrate to the participants the computer graphic principles we have applied. Three dimensional regional bone mineral density data describing the spine, proximal femur and temporal bone will be available for the participants to display and analyze. Additionally, these computer tools will be demonstrated using case material involving osteoporotic lateral spine radiographs, in vitro microtomography, and microradiography. Display and analysis functions to be presented will include rapid three-dimensinoal data set reorientation, orthogonal sectioning, image subtraction, and volume of interest analysis.
