Computer Systems
AVW is designed to run on all modern workstation platforms and today’s powerful “PC” systems. The effectiveness of AVW on these platforms without requiring special hardware has significantly contributed to its worldwide, multi-disciplinary distribution, acceptance and utilization. AVW is supported on the following computer platforms:
- Sun Microsystems workstations running Solaris 2.5+
- SGI workstations running IRIX 5.3+ and IRIX 6.2+
- Hewlett-Packard workstations running HP-UX 10.02+
- Compaq (DEC) Alpha workstations running Digital UNIX 4.0+
- IBM RS/6000 workstations running AIX 4.2+
- PC (Intel) systems running Linux (Red Hat 6.0+ or compatible)
- PC systems running Windows 95, 98, NT 4.0 and 2000
Imaging Modalities
AVW can be used effectively for almost any conceivable image visualization and/or analysis task, independent of the source of the image data. It is not restricted to biomedical images, having been successfully used for image processing and analysis tasks in non-biomedical fields such as geology, archeology, meteorology and photography, to name a few. However, it has been and is most commonly used in and provides procedural support for the following biomedical imaging modalities:
- X-ray Computed Tomography (CT)
- Magnetic Resonance Imaging (MRI)
- Positron Emission Tomography (PET)
- Single Photon Emission Computed Tomography (SPECT, ECT)
- Ultrasound Imaging
- Biomagnetic Imaging
- Radiographic Imaging
- Auto-radiographic Imaging
- 2-D and 3-D Microscopy Imaging (Light, Electron, Confocal, Atomic Force)
Image File Formats
AVW provides support for reading most standard computer image and picture formats, including the emergent DICOM standard for radiologic images. It also supports exporting (writing) image data in several of these formats. More formats are added continuously as they are identified and user demands dictate.
