[edit] Electron Microscopy

Main article: Electron microscope

The electron microscope is a microscope that can magnify very small details with high resolving power due to the use of electrons as the source of illumination, magnifying at levels up to 2,000,000 times.

Electron microscopy is employed in anatomic pathology to identify organelles within the cells. Its usefulness has been greatly reduced by immunhistochemistry but it is still irreplaceable for the diagnosis of kidney disease, identification of immotile cilia syndrome and many other tasks.

Other proposed or developed techniques include:

• diffuse optical tomography
• elastography
• electrical impedance tomography
• optoacoustic imaging
• ophthalmology
  • A-scan
  • B-scan
  • corneal topography
  • Heidelberg retinal tomography
  • Optical coherence tomography
  • scanning laser ophthalmoscopy

Some of these techniques are still at a research stage and not yet used in clinical routines.

[edit] Non-diagnostic imaging

Neuroimaging has also been used in experimental circumstances to allow people (especially disabled persons) to control outside devices, acting as a brain computer interface.
