Modern imaging techniques
Description
Modern imaging techniques for medical diagnostics
Some modern imaging techniques for medical diagnostics will be presented:
- X-ray imaging technique originally started with direct exposure of a photographic plate and today uses a scintillation crystal screen combined with a digital light-sensitive chip the size of the area to be imaged.
- The X-ray technique was extended with the CT (Computer Tomography) scanner in which the X-ray source including a (later several) circular row of detectors orbits the patient.
- Ultrasound or echoscopy uses acoustic transducers that emit sound waves into the body. The size of the reflected sound depends on differences in acoustic impedance. A probe detects this as an echo. Signal processing SW calculates the image from this.
- Nuclear medicine uses, among other things, organic substances labelled with radioactive isotopes. This specific organic material is injected into the patient. A gamma camera or PET scanner detects the emitted gamma quants at the site of the diagnosis to be made.
- Very recently, the combination of PET-CT has entered the market.
- MRI (1980s) will be discussed in detail. This is an imaging technique that is still under development and relies on imaging the effective proton spin density.
Various clinical applications will be discussed
