Due to limitations of REDCap discussed below, our TORP imaging database was not meant to replace our TOPDP database; rather, it was meant to be utilised in conjunction with the TOPDP database.
The capillary was located approximately 1.8 mm below the imaging surface and at the centre (x = 25 mm) of the phantom.
Time-resolved CE-MRA is an excellent method of assessing small vessel patency, and is particularly useful when imaging the below-the-knee vessels, where it is superior to standard CE-MRA [122, 123].
These include negative, near-zero, and indefinite permittivity or permeability indices; backward waves and backward phase matching in nonlinear optics; and potential applications of metamaterials for perfect absorption, cloaking, and imaging below the diffraction limit using super- and hyperlenses.
Glutaraldehyde-preserved samples were intended for ultrastructural analyses with TEM (see below) and also imaging with light microscopy; formalin-preserved samples were intended for quantification and/or imaging.
The off-the-shelf aspheric singlet that was used as the objective lens was designed for use in air, which increased the specular reflection from the tissue surface and caused spherical aberration when imaging below the tissue surface.
A FSL is capable of optically imaging well below the diffraction limit and works by enhancing and scattering evanescent waves to the far field which is then used to numerically reconstruct the object image [S. Durant, J. Opt. Soc. Am. B. 23(2383) 2383; Z. Liu, S. Durant, H. Lee, Y. Pikus, N. Fang, Y. Xiong, C. Sun, X. Zhang, Nano Lett. 7 (2007) 403].
All neonates were sedated during imaging (see below).
Nerterets et al. [ 24], reported tumor diameters below 0.025 cm via imaging with X-ray phase-contrast micro-CT in-line holography.
Tissues were washed thoroughly in PBT four times for 30 min or longer and mounted on glass slides for imaging (see below for the mounting protocol).
