4Q is a medical image analysis and annotation tool. It is a DICOM reader that depicts and analyzes volumetric information in 4D. Tissue objects are defined by a region of interest over image objects segmented using single touch (mouse and cursor) or a fully automatic saccadic eye movement model. Both trigger region growing to edges in edge space. Object detection is automatically propagated to neighboring images for multi-image studies. The edge space I am using is defined by an article published by me in Magnetic Resonance in Medicine 37(3):418-24. 1997.
Tissue objects are labeled by creating a memory file and labeling and adding observations from object regions of interest. Object recognition discriminating power is proportional to the number of labeled observations you add. You can create as many memory files as you like.
