Magnetic field uniformity (homogeneity), also known as magnetic field uniformity, refers to the identity of the magnetic field within a specific volume limit, that is, whether the magnetic field lines across the unit area are the same. The specific volume here is usually a spherical space. The un...
Medical imaging is a very important part of the medical field. It is a medical image produced through various imaging equipment, such as X-ray, CT, MRI, etc. Medical imaging technology has become more and more mature. With the advancement of digital technology, medical imaging has also ushered in...
In the previous article, we discussed the physical conditions that patients may have during MRI and why. This article mainly discusses what patients should do to themselves during MRI inspection to ensure safety.
1. All metal objects containing iron are prohibited
Including hair clips, co...
When we go to the hospital, the doctor will give us some imaging tests according to the need of the condition, such as MRI, CT, X-ray film or Ultrasound. MRI, magnetic resonance imaging, referred to as “nuclear magnetic”, let’s see what ordinary people need to know about MRI.
&...
Radiological imaging is critical to complement clinical data and support urologists in establishing appropriate patient management. Among different imaging modalities, computed tomography (CT) is currently considered the reference standard for the evaluation of urological diseases due to its wide...
AdvaMed, the medical technology association, announced the formation of a new Medical Imaging Technologies division dedicated to advocating on behalf of companies large and small on the important role medical imaging technologies, radiopharmaceuticals, contrast agents and focused ultrasound devic...
Healthcare professionals and patients depend on magnetic resonance imaging (MRI) and CT scan technology to analyze soft tissues and organs in the body, detecting a range of issues from degenerative diseases to tumors in a non-invasive manner. The MRI machine utilizes a powerful magnetic field and...
Here, we’ll briefly delve into three trends that are enhancing medical imaging technologies, and consequently, diagnostics, patient outcomes, and healthcare accessibility. To illustrate these trends, we’ll use magnetic resonance imaging (MRI), which utilizes radio frequency (RF) signa...
In the medical imaging department, there are often some patients with MRI (MR) “emergency list” to do the examination, and say that they need to do it immediately. For this emergency, the imaging doctor often says, “Please make an appointment first”. What is the reason?
F...
As the aging population, emergency departments are increasingly handling a greater number of elderly individuals who falls. Falling on even ground, such as in one’s home, is frequently a leading factor in causing a brain hemorrhage. While computed tomography (CT) scans of the head are frequ...
The previous article briefly introduced the difference between X-ray and CT examination, and let’s then talked about another question that the public is more concerned about at present – why can chest CT become the main physical examination item?
It is believed that many people have ...
The purpose of this article is to discuss the three types of medical imaging procedures that are often confused by the general public, X-ray, CT, and MRI.
Low radiation dose–X-ray
How did the X-ray get its name?
That takes us back 127 years to November. The German physicist Wilhelm ...
