Medical image processing and analysis for nuclear medicine diagnosis

摘要

The design and implementation of Medical Image Processing and Analysis for Nuclear Medicine Diagnosis on personal computer which was developed using software such as Borland Delphi 6.0 for image processing and analysis. This research provides the following facilities: (1) DICOM viewer which can display various standard formats of digital image data both single frame, multiframes and cine loop such as DICOM, INTERFILE, BITMAP, JPEG and JPEG2000. (2) Image processing which has also the capabilities to zoom in/out and contrast/color map. (3) Image analysis which determine the pixel values in a ROI that can be set up in various forms such as rectangle, ellipse, line and polygon. Thence, Semi-auto ROI setting that sets ROI semi-automatically on region of expected disease. Additionally, more than one ROI can be set in a single image. (4) Nuclear medicine diagnosis which are more functions on nuclear medicine for renal study such as calculation of Glomerular Filtration Rate (GFR), Effective Renal Plasma Flow (ERPF), and plot of the Time Activity Curve or Renogram. Finally, This research was tested with the DICOM 3.0 standard image compared the APEX-XPERT Program. The result showed that no significant difference can be found (α= 0.05).
