Quantitative stereology and radiologic image analysis. Part I: Computerized tomography and ultrasound.
The interpretation of two-dimensional radiographs or computerized tomography (CT) or ultrasound (US) sections with inferences made about three-dimensional anatomy is the foundation of diagnostic radiology. A large variety of estimation methods which can be applied to two-dimensional CT/US sections to estimate their three-dimensional properties is presented. The techniques are easily utilized in a research or clinical setting, do not require computerization, and can provide statistically accurate three-dimensional information based on two-dimensional sampling with a minimum of effort. Although the examples are directed at diagnostic radiology, the estimation procedures may be employed in analogous fields such as microscopy or section anatomy.
