What a nice visual for demonstrating frequency and energy states.

This is such an impressive demonstration of the MRI concept

The best illustration about the concept of spinning and resonance in MR imaging!

This is really visual and practical process to understand resonance vibration.

Caltech Team Develops First #Noninvasive Method to Continually Measure True Blood Pressure Solving a decades-old problem, a multidisciplinary team of #Caltech #researchers has figured out a method to noninvasively and continually measure blood pressure anywhere on the body with next to no disruption to the patient. A device based on the new technique holds the promise to enable better vital-sign monitoring at home, in hospitals, and possibly even in remote locations where resources are limited. The new patented technique, called #resonancesonomanometry, uses #soundwaves to gently stimulate #resonance in an #artery and then uses #ultrasoundimaging to measure the artery's resonance frequency, arriving at a true measurement of blood pressure. In a small clinical study, the device, which gives patients a gentle buzzing sensation on the skin, produced results akin to those obtained using the standard-of-care blood pressure cuff. "We ended up with a device that is able to measure the absolute blood pressure—not only the systolic and diastolic numbers that we are used to getting from blood pressure cuffs—but the full waveform," says Yaser Abu-Mostafa (PhD '83), professor of electrical engineering and computer science and one of the authors of a new paper describing the technique and device in the journal PNAS Nexus. "With this device you can measure blood pressure continuously and in different sites on the body, giving you much more information about the #bloodpressure of a person." https://lnkd.in/exuEjsMH

𝑩𝒂𝒔𝒊𝒄 𝑪𝒐𝒏𝒆𝒄𝒑𝒕 𝒐𝒇 𝑴𝑹𝑰 The concept of resonance is central to MRI technology. The radiofrequency pulse applied in MRI is designed to match the resonant frequency of hydrogen protons within the magnetic field. This resonance causes the protons to absorb energy and shift from their low-energy state to a high-energy state. As these protons relax back to their original state, they emit signals that are captured by detector coils which then reconstructed by computers into detailed images of Internal structures. This process is a 𝘱𝘳𝘢𝘤𝘵𝘪𝘤𝘢𝘭 𝘢𝘱𝘱𝘭𝘪𝘤𝘢𝘵𝘪𝘰𝘯 of resonance in medical engineering, making 𝐌𝐑𝐈 a critical tool for non-invasive diagnostics. #MRI #RadiologyEquipments #HealthcareTechnology #DiagnosticTools

Scientists at the University of New South Wales (UNSW) are pioneering a revolutionary project to develop a solar panel implant for the human retina, aimed at restoring lost vision. This neuroprosthetic device utilizes gallium-based semiconductors and miniature solar panels to convert light into electrical signals, bypassing damaged photoreceptors and transmitting visual information to the brain. While still in the proof-of-concept phase, the technology shows immense promise in potentially restoring vision for individuals with conditions like retinitis pigmentosa and age-related macular degeneration, albeit facing challenges regarding safety, efficacy, and neural compatibility.

A team of engineers and scientists from Caltech and the Keck School of Medicine at USC has created a noninvasive, headset-based device that can assess a patient’s stroke risk by monitoring blood flow and volume changes during a breath-holding test. The device uses a laser-based system and has demonstrated promising results in distinguishing between individuals with low and high stroke risk. “With this device, for the first time, we are going to have a way of knowing if the risk of someone having a stroke in the future is significant or not based on a physiological measurement,” says Simon Mahler, a co-lead author of the study. #laser #Caltech #headset #device #Predict #strokes #brain #blood #optical #spectroscopy #technique #medicine #breathhold #risk #demonstration #physiological #healthcare #businessdor Caltech Keck School of Medicine of the University of Southern California Caltech Electrical Solutions Headsets Healthcare Series Innovation Match Brain & Mind Hub Medicine Professional Headsets

I'm happy to share the publication of my paper, "Electromagnetic Force from Electric Vehicles: Potential electromagnetic interference source for subcutaneous implantable defibrillator," in Pacing and Clinical Electrophysiology journal. This research focused on EMI from EVs, specifically the Tesla Model 3, and how it could affect the functionality of subcutaneous implantable cardioverter-defibrillators (S-ICDs). This research is a collaboration between Wright State University Boonshoft School of Medicine/BIE Department and the FDA. We used a loop antenna device validated by the FDA to mimic an S-ICD antenna. We measured EMI in various locations and orientations inside and outside the vehicle. The highest voltages, which could potentially interfere with S-ICD operation, were detected around the cup holder inside the car. A Special Thanks to Kamil Salam, Tarun Goswami, and Abdul Wase for their invaluable contributions to this research.
