The development of new ultrasound (US) probes based on Capacitive Micromachined Ultrasonic Transducer (CMUT) technology requires an early realistic assessment of imaging capabilities. We describe a repeatable experimental protocol for US image acquisition and comparison with magnetic resonance images, using an ex vivo bovine brain as an imaging target.

Blood pressure monitoring is one of the essential vital signs, and for a majority of patients, measuring it utilizing non-invasive techniques provides accurate values. However, there are situations in which the blood pressure requires more exact, specific, and reliable measurements.

Glaucoma is a chronic disease with progressive degeneration of optic nerve fibers resulting in decreased visual field. Elevated intraocular pressure is considered the most important and the only treatable risk factor. This manuscript describes a simple, surgeon-friendly, non-incisional technique, named Ultrasound Cyclo Plasty, for reducing intraocular pressure in glaucoma patients.

However, there are many factors that can complicate placement of a peripheral intravenous cannula (PIV), and it is extremely common for PIV attempts to fail. PIV placement may be technically challenging in small...
FAQs
Cranial acoustic windows provide routes through which emitted sound waves can enter the brain with less obstruction from the skull. Selecting and aligning the probe with an appropriate window helps limit the effects of skull-related attenuation and distortion. This directly influences whether returning echoes form interpretable signals during transcranial imaging or ultrasound-based interventions.
Small changes in probe angle, applied pressure, or imaging depth alter how sound enters tissue and how returning echoes are captured. Appropriate adjustments help the operator obtain usable signals despite the skull’s attenuation and distortion. Maintaining suitable settings is therefore important for visualizing brain structures, assessing blood flow, and supporting consistent experimental or clinical targeting.
Applying a coupling medium is an early step in preparing the probe for transcranial examination or intervention. It supports the acoustic connection between the transducer and the examination region, allowing emitted waves and returning echoes to participate in signal formation. Consistent use helps the operator focus on positioning, orientation, pressure, angle, and depth.
Both applications require an appropriate cranial acoustic window and careful control of probe orientation, but their goals differ. Imaging placement aims to produce interpretable echoes for structures or blood flow, whereas neuromodulation placement supports accurate targeting with focused ultrasound. In either case, skull-related attenuation and distortion make deliberate positioning important for reliable results.
The operator first applies coupling medium, then places and orients the transducer at an appropriate cranial acoustic window. Pressure, angle, and depth are adjusted to help sound waves enter the brain and to improve returning signals. The final position should provide interpretable data or support the intended intervention while remaining consistent across examinations or experimental sessions.
Consistent placement supports transcranial imaging of brain structures and blood flow, as well as targeting for focused ultrasound neuromodulation. It also improves reproducibility across examinations, experiments, and treatment protocols. By reducing variation in how the probe is positioned and oriented, researchers can more reliably compare acquired signals or intervention conditions within neuroscience studies.
