Obsah:
- Sketches of the standard imaging modalities : different ways of creating visible contrast among tissues
- Image quality and dose : what constitutes a "good" medical image?
- The creation of two-dimensional x-ray projection maps (shadowgrams) of the body : differential attenuation of x-rays by tissues
- 20th century (analog) radiography and fluoroscopy : capturing the x-ray shadow with a film cassette or with an image intensifier tube plus electronic optical camera combination
- Radiation dose and radiogenic risk : ionization-induced damage to DNA can cause stochastic, deterministic, and teratogenic health effects and how to prevent them
- 21st century (digital) imaging : computer-based representation, acquisition, processing, storage, transmission, and analysis of images
- Digital planar imaging : replacing film and image intensifiers with solid state, electronic image receptors
- Computed tomography : superior contrast in three-dimensional x-ray attenuation maps
- Nuclear medicine : contrast from differential uptake of a radiopharmaceutical by tissues
- Diagnostic ultrasound : contrast from differences in elasticity or density across tissue interfaces
- MRI in one dimension and without relaxation : a gentle approach to a challenging subject
- MRI with T1 and T2 relaxation and in three dimensions
- Evolving and experimental modalities.
