Exploring Electromagnetic and Magnetic Technologies 🧲⚡ Electromagnetic and magnetic testing are cutting-edge techniques in non-destructive evaluation (NDE). They involve applying electric currents and magnetic fields to examine conductive materials, revealing surface and sub-surface defects. These defects alter electrical conductivity and magnetic permeability, leading to changes in flow patterns, intensity, and phase that we can leverage for identification. Recent research has made significant strides in generating powerful magnetic fields, with developments allowing the activation of fields exceeding 8 Tesla within mere femtoseconds using all-optical methods, as noted by Sederberg et al., 2020. The world of electromagnetic and magnetic testing encompasses a range of techniques, including Alternating Current Field Measurement (ACFM), Eddy Current Testing (ECT), Magnetic Flux Leakage (MFL), Remote Field Testing (RFT), Magnetic Barkhausen Noise (MBN), Electromagnetic Ultrasonic Guided Wave Testing (EUGW), Metal Magnetic Memory (MMM), Tangential Eddy Current (TEC), Pulsed Eddy Current Testing, Eddy Current Array (ECA), Remote-Field Eddy Current Testing, Low-Frequency Eddy Current Testing, and Electromagnetic Acoustic Transducer (EMAT).

The only true standard out there for the Certification in Airborne / Structureborne Ultrasound is ISO 18436 Part 8 Ultrasound Certification. The training that so many companies take for certification has been portrayed as meeting the intent of ASNT SNT TC-1A and ASNT Does Not have a standard for airborne / structure-borne Ultrasound! Never have. While this is a good course you attended and I may have taught you in the past let you learn a lot about the use of Ultrasound Detection Equipment, the claim is not fact-based that this training meets the intent of ASNT SNT-TC-1A. Under Table 6.3.1A Recommended Initial Training and Experience Levels the standards are only for the following; Acoustic Emissions Electromagnetic (AC Field Measurements, Eddy Current, Remote Fields) Ground Penetrating Radar Guide Wave Laser Methods ( Profilmetry, Holograph/Shearography) Leak Testing ( Bubble Testing, Pressure C change, Halogen Diode, Mass Spectrometer) Penetrant Testing Magnetic Flux Leakage Magnetic Particle Microwave Technology Neutron Radiography Thermal/Infrared Pulse Echo Ultrasonic Testing (Basic Course {Angel Beam, Straight Beam, Contact, Immerison} Phase Array, Time of Flight Diffraction) When I learned this in 2016 it made me question how I could continue with this misrepresentation of the training that I was providing for that company. Fortunately, I found a company that let me develop content that follows the guidelines outlined in the ISO 18436 Part 8 Ultrasound Certification Recommendations. This material is far superior to the content I developed for the last company in 2010. Come check out our CAT 1-3 ASU or IRT certification which has been reviewed by 3rd Parties to confirm our conformity to the ISO 18436 outline for Ultrasound and Infrared Training. #UltrasoundCertifiaction #ISO18436Part8 #IRISS

Did you know that a lot of great #inventions have been discovered by accident? Such as #xrays! Do lets celebrate the International Day of #Radiology taking place today! 🤔 When and how did it happen - and who made it happen? On November 8, 1895, Wilhelm Conrad #Roentgen, a German physicist, accidentally discovered X-rays while conducting experiments with cathode-ray tubes. He noticed that a fluorescent screen in his lab was glowing even when the tube was covered, indicating the presence of invisible rays. He named these rays "X-rays" (X for unknown) and began studying their properties. Roentgen conducted further experiments to understand the properties of X-rays. He found that X-rays could pass through most materials, including #human tissue, and create shadow images on photographic plates. This discovery opened the door to their use in #medicine. X-rays quickly found applications in the medical field for #diagnosing fractures, locating foreign objects within the body, and visualizing internal anatomical structures. Roentgen's work earned him the first #NobelPrize in Physics in 1901. Today, X-rays are an integral part of #medical #diagnostics, #dentistry, materials #science, #airport security, and various #industrial applications. They have saved countless lives and continue to be a powerful tool for exploring the invisible world of the human body and beyond.

Training for intrapartum sonography using optical ultrasound simulation - The Optical Positioning Ultrasound Simulator and user interface The intrapartum Optical Positioning Ultrasound Simulator consists of (A) a scanning pad, webcam, and replica probe. The scanning pad was mounted vertically to replicate real-life probe positioning, and the pad orientation was rotated 45 degrees to accommodate the probe movements between the sagittal and transverse planes. B, Intrapartum simulator user interface with target plane, main scan image ‘cervical dilatation’, probe movement instructions, and reference image. C, Intrapartum angle of progression module demonstrating an acceptable image and measurement (score ≥7/10) with simulator feedback. D, Intrapartum angle of progression module demonstrating an unacceptable image and incorrect measurement (score <7/10) with simulator feedback. https://ow.ly/6bLj50RnTwi

Basic concept of Radiography Test (RT) is explained in this article!!! https://lnkd.in/dugeRNCw

My new paper : This Study compares the diagnostic quality of CT body scout views with cranial CT versus conventional X-ray radiography.

Could anyone recommend a comprehensive CT simulation software suitable for training radiographers in both basic and advanced CT techniques? #computedtomography #simulation #radiographers

The X-ray Tube: X-ray tubes are found in a wide variety of imaging devices, Computed Tomography (CT), portable x-ray machines, mammography machines, fixed position x-ray machines, fluoroscopy units, and c-arm x-ray machines. Medical x-rays are produced in a glass enclosed vacuum tube. A high voltage differential is applied across a gap in a vacuum tube between a cathode and an anode. The anode is the target for the electrons that are accelerated across the vacuum and the anode is usually made of a metal, often tungsten. When the voltage differential results in an electron crossing over the gap and impacting the metallic anode the electron slows down and liberates energy as heat and x-rays. The majority of the energy is liberated as heat. This type of interaction that results in x-ray generation, has been called by the “braking of the electron”, the bremsstrahlung effect. #radiology #xraytube
