Contrast, image

Alternatively, we may obtain a -weighted image by setting TE to a value in the middle of the range we are trying [Pg.317]

Although we now have a substantial level of understanding, it is far from complete. [Pg.318]

The contrast AM / M max is defined as the relative difference in image intensities M of neighbouring structures i and j [Manl], [Pg.245]

The relationship between image contrast and resolution was modelled... [Pg.211]

Figure Bl.17.4. Visualization of image contrast fomiation methods (a) scattering contrast and (b) interference contrast (weak phase/weak amplitude contrast). Figure Bl.17.4. Visualization of image contrast fomiation methods (a) scattering contrast and (b) interference contrast (weak phase/weak amplitude contrast).
The factor A has been measured for a variety of samples, indicating that the approximation can be applied up to quasi-atomic resolution. In the case of biological specimens typical values of are of the order of 5-7%, as detemiined from images with a resolution of better than 10 A [37,38]- For an easy interpretation of image contrast and a retrieval of the object infomiation from the contrast, such a combination of phase and amplitude hifomiation is necessary. [Pg.1638]

As was discussed above, the image contrast is significantly affected by the aberrations of the electron-optical... [Pg.1642]

Another specialized application of EM image contrast is mass measurement. Using the elastic dark-field image in the STEM or the inelastic image in the EETEM, a direct measurement of the scattering mass can be performed. Eor reviews on this teclmique see [60.61]. [Pg.1645]
