Analysis of the morphology, composition, and spacing of exsolution lamellae can provide essential information to understand geological processes related to volcanism and metamorphism. We present a novel application of APT for the characterization of such lamellae and compare this approach to the conventional use of electron microscopy and FIB-based nanotomography.

This video demonstrates the methodology for performing Reverse Phase Protein Arrays (RPPA) to study protein expression patterns from cell lysate. In RPPA, the lysate containing a mixture of proteins is printed on nitrocellulose slides and proteins of interest are analyzed using fluorescently labeled antibodies.
FAQs
Electronic timing determines when individual elements transmit or receive ultrasound. When wavefronts arrive in phase, they combine constructively in the selected direction, while coordinated timing also concentrates the beam at a chosen focus. This lets the examination sample different directions and depths without requiring physical movement of the transducer.
A small acoustic window helps the probe obtain images through restricted access points, including the spaces between the ribs. In cardiac examinations, this design supports viewing the heart despite the surrounding rib cage. The resulting electronically controlled beam can be directed rapidly to evaluate cardiac anatomy and motion in real time.
Rapid data acquisition allows successive ultrasound measurements to be assembled quickly, supporting real-time visualization rather than isolated observations. This is especially important when anatomy moves, because the examination can display changing cardiac structures and other motion while the beam is electronically directed across selected imaging regions.
Electronic focusing concentrates transmitted and received sound information at selected locations, improving control over where the examination gathers imaging data. Combined with beam steering, this permits targeted assessment of a chosen anatomical region. Clinicians can therefore examine specific structures or directions while using the same relatively small acoustic access point.
In medicine, common uses include cardiac imaging, assessment of blood vessels, examination of abdominal structures, and evaluation of other organs. The probe is particularly useful when the examination requires rapid visualization through a limited acoustic window. Its steering and focusing capabilities support targeted diagnostic studies across these anatomical settings.
The resulting images can show both anatomy and motion, allowing clinicians to assess structures as well as their changing appearance during the examination. In the heart, this supports real-time visualization; in vascular, abdominal, and other organ studies, the same imaging approach helps direct attention to the selected diagnostic region.
