Thank you!

X-Ray

roughly 2k x 2k pixels

around 100μm per pixel

10^-2

10^-3

10^-6

10^-9

micrometer

millimeter

centimeter

nanometer

around 0.1mm per pixel

Typical voxel size:  1x1x1 mm^3

one voxel off -> one mm off!

MRI

MRI       1 mm^3

US        0.1 mm

Fluorescence

light passing / reflection

light scattering

specific wavelength

Confocal

can be 3D

It's all numb3rs...

Electron

Microscopy

Transmission Electron Microscope (TEM)

Scanning Electron Microscope (SEM)

is 3D!

extremely high resolution

100,000 X

5,000,000 X

Electrons instead of visible light

Shorter wavelength -> penetrates objects more deeply
