NM ImageNM Image The ProblemThe Problem
Product support is inconsistent DICOM NM object coding techniques very NM full-body display needs misunderstood NM cardiac display needs misunderstood Clinical Analysis Applications results distribution unsupported
Poor communiction during product purchase NM Users are not adept at getting these requirements accurately
included in RFPs Vendors (especially of general purpose systems) are not adept at
accurately representing their support for such features

Render Dynamic Result Screens Capture Dynamic Results using the following DICOM Objects:
• Multi-Frame Secondary Capture– Grayscale Byte– True Color
Render Static Result Screens Capture the Static Results using either
• single frame• Multi-frame (preferred)
Must generate appropriate Secondary Capture objects from any Result Screens rendered.

Scale “intelligently” to avoid presenting postage-stamp size NM images
Allow user to select different vectors/framesets of complex multi-frame images
Allow user to separately adjust intensity for different framesets (eg, phases) in the same “image”
