Quantitative Medical Imaging

The field of medical imaging is undergoing a radical shift, from subjective interpretation to quantitative analysis and measurement. This transformation is well established in the clinical trials arena, and is beginning to enter the diagnostic field as well. This paper will consider the implications of this change in terms of instrumentation, procedure, and analysis. It will include a brief rev...

Quantitative Ultrasonic Tomographic Imaging

An ultrasonic transmission technique is described which images the velocity variation within metal parts. The arrival time of the first ultrasonic pulse to traverse the object is detected and displayed as a gray scale on a cathode ray tube while the part is being scannerJ hori:tontally and vertically. The velocity variation imaged within severa 1 cast turbine parts will be shown. ihe system can...

Quantitative Hyperspectral Reflectance Imaging

Hyperspectral imaging is a non-destructive optical analysis technique that can for instance be used to obtain information from cultural heritage objects unavailable with conventional colour or multi-spectral photography. This technique can be used to distinguish and recognize materials, to enhance the visibility of faint or obscured features, to detect signs of degradation and study the effect ...
