abstract = {Experimental evidence on testing a non-ultrasonic-based probe for a new approach in
transluminal elastography was presented. The proposed modality generated shear waves by inducing
oscillatory rotation on the lumen wall. Detection of the propagated waves was achieved at a set of
receivers in mechanical contact with the lumen wall. The excitation element of the probe was an
electromagnetic rotational actuator whilst the sensing element was comprised by a uniform anglewise
arrangement of four piezoelectric receivers. The prototype was tested in two soft-tissue-mimicking
phantoms that contained lumenlike conduits and stiffer inclusions. The shear wave speed of the
different components of the phantoms was characterized using shear wave elastography. These values
were used to estimate the time-of-flight of the expected reflections. Ultrafast ultrasound imaging,
based on Loupas’ algorithm, was used to estimate the displacement field in transversal planes to the
lumenlike conduit and to compare against the readouts from the transluminal transmission–reception
tests. Experimental observations between ultrafast imaging and the transluminal probe were in good
agreement, and reflections due to the stiffer inclusions were detected by the transluminal probe. The
obtained experimental evidence provided proof-of-concept for the transluminal elastography probe
and encouraged further exploration of clinical applications.},
