The basic process by which imaging particle analysis is carried out is as follows: A digital camera captures an image of the field of view in the optical system.; A gray scale thresholding process is used to perform image segmentation, segregating out the particles from the background, creating a binary image of each particle.
Label-free cell cycle analysis. The phase shift induced by cells has been shown to be correlated to the cell dry mass. The cell dry mass can be combined with other parameters obtainable by digital holography, such as cell volume and refractive index, to provide a better understanding of the cell cycle. [19] Label-free morphology analysis of cells.
Contrary to conventional phase contrast images [citation needed], phase shift images of living cells are suitable to be processed by image analysis software. This has led to the development of non-invasive live cell imaging and automated cell culture analysis systems based on quantitative phase contrast microscopy. [6]
Cytometers are the instruments which count the blood cells in the common blood test.. Cytometry is the measurement of number and characteristics of cells.Variables that can be measured by cytometric methods include cell size, cell count, cell morphology (shape and structure), cell cycle phase, DNA content, and the existence or absence of specific proteins on the cell surface or in the ...
The Coulter counter as invented by Wallace Coulter applies a direct current (DC) in order to count particles (cells), and produces electrical pulses of amplitude dependent on the size of cells. The cells can be modelled as electrical insulators surrounded by a conductive liquid which block a portion of the electrical path thus increasing the ...
A digital microscope is a variation of a traditional optical microscope that uses optics and a digital camera to output an image to a monitor, sometimes by means of software running on a computer. A digital microscope often has its own in-built LED light source, and differs from an optical microscope in that there is no provision to observe the ...

It is specifically a 2D cell migration approach to semi-quantitatively measure cell migration of a sheet of cells. [3] This scratch can be made through various approaches, such as mechanical, thermal, or chemical damage. [4] The purpose of this scratch is to produce a cell-free area in hopes of inducing cells to migrate and close the gap.
