Source: Amelia R. Adelsperger, Evan H. Phillips, and Craig J. Goergen, Weldon School of Biomedical Engineering, Purdue University, West Lafayette, Indiana High-frequency ultrasound systems are used to acquire high resolution images. Here, the use of a state-of-the-art system will be demonstrated to image the morphology and hemodynamics of small pulsatile arteries and veins found in mice and rats. Ultrasound is a relatively inexpensive, portable, and versatile method for the noninvasive...

We describe a new ultrasound-based vector tissue Doppler imaging technique to measure muscle contraction velocity, strain and strain rate with sub-millisecond temporal resolution during dynamic activities. This approach provides complementary measurements of dynamic muscle function and could lead to a better understanding of mechanisms underlying musculoskeletal disorders.

Source: Joseph H. Donroe, Rachel Liu; Yale School of Medicine, USA Point of care ultrasound (POCUS) is used by clinicians for diagnosis, ongoing monitoring, and/or procedural guidance at the time of patient care. Many medical schools are now teaching POCUS as a part of their basic clinical skills training, in addition to history, physical exams, and clinical reasoning. Besides being an independent skill, POCUS is also an incredibly useful tool for augmenting the teaching and learning of the...

This video demonstrates use of a rail-mounted high-frequency ultrasound probe to perform echocardiography on an anesthetized mouse. The methods describe both conventional two-dimensional and M-mode measurements of cardiac function in addition to newer, more powerful tools such as color Doppler, strain analysis, as well as general and targeted contrast imaging.
FAQs
Image formation depends on how tissues interact with sound. The transducer sends high-frequency waves into the body, then detects echoes returning from internal structures. Differences in tissue acoustic properties alter the returning signals, and the system displays those differences as image patterns. Clinicians can use these patterns to examine structures during the same clinical encounter.
Real-time display lets clinicians connect an observed finding with the patient's current condition and make decisions without waiting for a delayed result. During bedside assessment, this timing supports immediate clinical evaluation and management. The advantage is particularly relevant when patients are being assessed in emergency, critical care, inpatient, or ambulatory settings.
The lack of ionizing radiation is one reason bedside ultrasound can fit directly into clinical assessment. Combined with portability and rapid results, this characteristic supports its use across emergency, critical care, inpatient, and ambulatory environments. Imaging can occur where the patient is being evaluated, providing information during the immediate decision-making process.
The examination can target organs, blood vessels, the heart, lungs, and soft tissues. This broad coverage allows clinicians to select an assessment that matches the immediate clinical question rather than relying on a single anatomical application. In medicine, the same portable approach can therefore contribute to evaluations across multiple body systems and points of care.
During vascular access or fluid drainage, clinicians can use bedside ultrasound to guide the procedure at the point of care. The transducer supplies live anatomical information while the intervention is being performed, linking imaging with the procedural task. This application extends the technique beyond assessment and makes it useful when immediate visual guidance is needed.
Emergency departments, critical care units, inpatient wards, and ambulatory settings all fall within the clinical scope of bedside ultrasound. Its portability allows imaging to occur where the patient is being evaluated, while rapid results can feed directly into the current assessment. The method is therefore suited to situations in which location and timing affect clinical decisions.
