Phase detection imaging

Figure 2. TMAFM phase detection images (2x2 pm ) of the 14,500-63,000-14,500 MBuM copolymer (Sample A) aimealed at 140 C for 48 hours and then either (a), slowly cooled or (b) quenched with liquid nitrogen.

A very large image signal appears in CRAMPS spectra because the x-component of the magnetization is different from the y-component. Therefore, half of the spectral region is abandoned. However, some quadrature-phase detection CRAMPS (QD-CRAMPS) methods which cancel the image signal have been reported. ... 

Measurements were performed with a Nanoscope Ilia/ Dimension 3000 (Digital Instruments) in the tapping mode at ambient conditions, using the electronic extender module allowing simultaneously the phase detection and height imaging. We used Si-tips (model TESP) with a resonant frequency...

By using microbubble destructive techniques, such as stimulated acoustic emission (SAE), or agent detection imaging (ADI), it is possible to exploit the liver specific phase of some agents, which is probably mediated by Kupffer cell uptake. Interaction with...
