AbstractDigital medical informatics and images are commonly used in hospitals today,. Because of the interrelatedness of the radiology department and other departments, especially the intensive care unit and emergency department, the transmission and sharing of medical images has become a critical issue. Our research group has developed a Java-based Distributed Object Medical Imaging Model(DOMI...

The radiation spectrum includes forms of radiation that carry various energy levels. Radiation forms, such as x-radiation, which carry sufficient energy to overcome binding energies of electrons and to eject them from their atomic orbits, can cause the formation of ions in the matter through which they travel, and are termed ionizing radiation. Ionizing radiation may also dissociate molecular b...

Medical imaging is a broad field and we shall focus here primarily on only two areas: x-ray transmission tomography (CAT-scans); and emission tomography (PET and SPECT scans). We use transmission tomography to illustrate the non-iterative filteredbackprojection (FBP) approach to imaging, and emission tomography, mainly singlephoton emission computed tomography (SPECT), to illustrate iterative m...

Filtering is always the root process in many medical image processing applications. It is aimed at reducing noise in images. Any post-processing tasks, e.g., visualization, segmentation may benefit from the reduction of noise. Bilateral filtering smoothes images while preserving edges, by means of a nonlinear combination of nearby image values. This method is noniterative and simple. It combine...

Physicians are often faced with the dilemma of trying to do what is best for the patient, sometimes deciding to use a technological innovation. The profession has drawn up guidelines for common methods in imaging. These include informed consent, intravenous use of contrast media, ten-day rule, invasive procedures like angiograms (peripheral, cerebral, coronary, renal and so on), and image-guide...

Medical imaging is essential to screening, early diagnosis, and monitoring responses to cancer treatments and, when used with other diagnostics, provides guidance for clinicians in choosing the most effective patient management plan that maximizes survivorship and quality of life. At a gathering of agency officials, patient advocacy organizations, industry/professional stakeholder groups, and c...

The concepts and realization of the medical imaging workstation are described. The following concepts are described: presentation and processing pipeline, resource management (CPU and memory), including caching and antifragmentation strategy, software process decomposition and decomposition rules. The actual realization figures serve as illustration for the justification of some of the concepts...
