Diagnostic ultrasound imaging has proven to be effective in diagnosing various respiratory diseases in human and animal subjects. We demonstrate a comprehensive ultrasound protocol utilized by Dr. Zuo's lab to analyze diaphragm kinetics specifically in mouse models. This is also a non-invasive research technique which can provide quantitative information on mouse respiratory muscle function.

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: Ali Bazzi, Department of Electrical Engineering, University of Connecticut, Storrs, CT. Three-phase wound-rotor synchronous generators are the main source of electrical power worldwide. They require a prime mover and an exciter in order to generate power. The prime mover can be a turbine spun by fluid (gas or liquid), thus the sources of the fluid can be water running off a dam through a long nozzle, steam from water evaporated using burned coal, etc. Most power plants including coal,...

Source: Ali Bazzi, Department of Electrical Engineering, University of Connecticut, Storrs, CT. Three-phase wound-rotor synchronous motors are less popular than permanent magnet rotor synchronous motors due to the brushes required for the rotor field. Synchronous generators are much more common and available in most existing power plants, as they have excellent frequency and voltage regulation. Synchronous motors have the advantage of almost 0% speed regulation due to the fact that the rotor...

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...
FAQs
The piezoelectric transducer alternates between sending sound pulses and detecting echoes that return from internal structures. The system uses the timing of each echo to estimate where a structure lies and uses echo strength to create visual patterns. Because this processing occurs continuously, clinicians can observe anatomical structures as they are examined in real time.
Doppler techniques provide information about moving blood rather than only showing stationary anatomy. They assess both the direction and velocity of blood flow, giving clinicians a way to examine circulation within the body. This capability expands ultrasound assessment beyond organ structure and supports applications in which blood movement is clinically relevant, including cardiovascular evaluation.
Ultrasound produces images with high-frequency sound waves rather than ionizing radiation. That distinction makes it useful when clinicians need repeated or real-time examinations of organs, soft tissues, blood flow, or fetal development. Its safety-related imaging characteristic also helps explain why ultrasound has a broad role across medical settings, alongside its ability to display ongoing motion.
During an examination, the transducer sends sound pulses into the body and receives the echoes returning from internal structures. The machine immediately processes echo timing and signal strength into an image for clinical interpretation. This workflow allows the operator to examine anatomy dynamically, rather than relying only on a static image captured after the examination.
Clinical uses include examining organs, assessing blood flow, monitoring fetal development, and investigating soft-tissue abnormalities. The same imaging platform can therefore support both structural and motion-related assessment, especially when Doppler information is added. Its value extends across medicine because these targets represent different types of findings that can be visualized without ionizing radiation.
Portable systems extend ultrasound beyond conventional imaging locations, making the technology useful in emergency care and other settings where access and speed matter. Ultrasound guidance also supports procedures in anesthesia and contributes to care in cardiology. These applications connect real-time imaging with immediate clinical decisions and with procedures that benefit from visualizing relevant anatomy.
