The American Society of Echocardiography (ASE) is a professional organization dedicated to advancing the practice of echocardiography and improving patient care through education, research, and advocacy. Established in 1975, ASE aims to promote the science and practice of the field of echocardiography, which utilizes ultrasound technology to create images of the heart and assess its function and structure.
Cranial ultrasound, also known as a cranial sonogram, is a non-invasive imaging technique used to visualize the brain and other structures within the cranium. It employs high-frequency sound waves to create real-time images and can be particularly useful in assessing conditions affecting the brain in infants, especially in newborns whose fontanelles (soft spots on the skull) are still open, allowing for better ultrasound penetration.
Doppler ultrasonography, often simply referred to as Doppler ultrasound, is a medical imaging technique that uses high-frequency sound waves to assess the flow of blood within the body. This technique leverages the Doppler effect, which is the change in frequency or wavelength of sound waves in relation to an observer moving relative to the source of the sound. In Doppler ultrasonography, sound waves are emitted towards moving blood cells.
Medical ultrasound, also known as sonography, is a diagnostic imaging technique that utilizes high-frequency sound waves to create images of internal structures within the body. It is a non-invasive and safe procedure commonly used in various medical fields, including obstetrics, cardiology, and abdominal imaging. ### Key Features of Medical Ultrasound: 1. **How It Works**: A device called a transducer emits high-frequency sound waves that travel through the body and reflect off tissues and organs.
Roger Sanders may refer to multiple individuals, as it is not an uncommon name. One notable figure is Roger Sanders, an American lawyer and author known for his work in intellectual property law.
Tissue Doppler echocardiography (TDE) is an advanced echocardiographic technique used to assess myocardial (heart muscle) function. It utilizes the Doppler effect to measure the velocities of the heart muscle as it contracts and relaxes, providing critical information about the health and function of the heart.
Nuclear medicine physicians are medical doctors who specialize in diagnosing and treating diseases using radioactive materials and imaging techniques. They utilize a variety of nuclear medicine procedures, which often involve the administration of small amounts of radioactive substances to patients. These substances help in the visualization of physiological functions and processes within the body.
Hair removal refers to the process of eliminating unwanted hair from the body. This can be done using a variety of methods, each with its own advantages and disadvantages. Common hair removal techniques include: 1. **Shaving**: Using a razor or electric shaver to cut hair at the skin’s surface. It's quick and easy but may lead to irritation or ingrown hairs.
Laser ablation is a process in which material is removed from a solid (or occasionally liquid) surface by irradiation with a laser beam. The laser energy is focused onto the material, causing it to heat and vaporize, or to be ejected in particles or as a plume of vapor. This technique is widely used in various fields, including materials science, surface engineering, and medical applications.
Mode locking is a technique used in lasers to generate short pulses of light (typically in the picosecond to femtosecond range) by forcing different longitudinal modes of the laser cavity to oscillate in phase. In a typical laser, multiple longitudinal modes (which are different frequencies of light that can oscillate in the cavity) can be present, but they may not be in sync with each other. This lack of synchronization results in a continuous wave output.
The Pascal Photocoagulator is a type of laser device used primarily in ophthalmology for the treatment of various eye conditions, particularly those involving the retina. The term "Pascal" refers to the specific technology used in the device, which allows for a more efficient and effective method of laser photocoagulation. Photocoagulation is a procedure that uses laser energy to create small burns in specific areas of the retina.
A computational human phantom is a digital or virtual representation of the human body used in various fields such as medical imaging, radiation therapy, and dosimetry. These phantoms simulate the anatomical and physiological properties of human tissues and organs, allowing researchers and medical professionals to study and analyze interactions between radiation, electromagnetic fields, and biological tissues without the need for physical trials on real human subjects.

Elscint is known for its innovation in design and efficiency in supplying customized solutions tailored to specific customer needs. They serve a range of industries, including automotive, electronics, and pharmaceuticals, among others.
Dynamic angiothermography is a medical imaging technique used to assess the vascularity and blood flow in tissues, particularly in the context of oncology and other vascular-related conditions. It combines dynamic thermography, which measures temperature changes on the skin's surface, with angiographic techniques that visualize blood vessels. The "dynamic" aspect refers to real-time monitoring of changes in blood flow and temperature in response to various stimuli or conditions.
Functional imaging is a type of medical imaging that provides information about the physiological and functional processes of the body, particularly the brain and other organs. Unlike structural imaging techniques, which focus on the anatomy and structure of tissues—such as X-rays, CT scans, and conventional MRI—functional imaging assesses how various tissues and organs are functioning in real time.
Medipix is a family of radiation detection chips developed for various applications, primarily in medical imaging and scientific research. The technology was originally developed by the CERN (European Organization for Nuclear Research) collaboration in the late 1990s, with a focus on high-resolution and high-rate particle tracking.
RTI-51 is a designation that can refer to various things depending on the context, but it is primarily associated with specific research and development projects or materials in scientific, industrial, or technological fields. Without further context, it's difficult to pinpoint a specific definition. It could involve an identifier for a research initiative, a type of technology, or an experimental program.
A semiconductor detector is a type of radiation detector that uses semiconductor materials to detect and measure ionizing radiation, such as alpha particles, beta particles, gamma rays, and X-rays. These detectors operate based on the principle that when ionizing radiation interacts with the semiconductor material, it generates electron-hole pairs (electrons and the absence of electrons, which acts as positive charges).
The Standardized Uptake Value (SUV) is a quantitative measure used in positron emission tomography (PET) imaging to assess the uptake of radiotracers, typically a form of glucose labeled with a radioactive isotope (such as FDG, or fluorodeoxyglucose). The SUV helps evaluate metabolic activity in tissues, which can be particularly useful in diagnosing and monitoring cancers.
Videokymography (VKG) is a high-speed imaging technique used to visualize and analyze rapid movements, often in the context of biological systems. It combines elements of video recording and kymography to capture dynamic processes. In particular, it is commonly used in the study of vocal fold dynamics in speech and voice research.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
