called focal-plane ray tracing where how an optical ray will be after a lens is determined based on a lens focal plane and how the ray crosses the plane. This...

radioligands allowed single-photon emission computed tomography (SPECT) and positron emission tomography (PET) of the brain. More or less concurrently, magnetic...

by which a suitably designed microscope can produce clear images of focal planes deep within a thick sample. This is used to reduce the need for thin...

Three-dimensional electrical capacitance tomography (3D ECT) also known as electrical capacitance volume tomography (ECVT) is a non-invasive 3D imaging technology...

object moves also. Only points from a particular slice, the so-called focal plane, will be always projected at the same location onto the detector and...

it is the diffraction pattern in the back focal plane that is moving with respect to the back-focal plane aperture. (In traditional ptychography the...

Terahertz tomography is a class of tomography where sectional imaging is done by terahertz radiation. Terahertz radiation is electromagnetic radiation...
