What is C-arm?
The introduction of C-arm revolutionized the surgery-room imaging and became the modality of choice for many surgeons and physicians. Right after its discovery, X-ray made its way into medicine and became an inseparable part of almost every medical procedure. From micro-computed tomography (micro-CT) in pre-clinical studies to radiography, fluoroscopy, and computed tomography in clinical studies, X-ray machines play a […]
Who is Wilhelm Röntgen?
The beginning of the history of radiology can be considered the story of discovery of X-rays by the German physicist Wilhelm Röntgen in 1895. Although before him, scientists such as Arthur Goodspeed, an American physicist, had also observed evidence of the existence of X-rays, but none of them focused on this issue and did scientific […]
Discovery of X-Rays
X-rays were accidentally discovered in 1895 by Wilhelm Roentgen, a German physicist, who received the first Nobel Prize for the discovery of X-rays, in 1901. Wilhelm Roentgen At the age of 50, while doing research at the University of Würzburg, Röntgen accidentally discovered X-rays while working with cathode ray tube. According to Philip Lenard²’s earlier […]
X-ray Based Imaging Modalities
Radiography, mammography, fluoroscopy, CT and micro-CT are the most important X-ray based imaging modalities. Radiography Radiography[1] or as called by some, plain X-ray, has made so many advancements since the discovery of X-rays by Wilhelm Roentgen[2] in 1895. Nowadays radiology facilities are an inseparable part of any hospital and emergency center. A radiography room contains […]
What do you know about X-ray and its applications?
X-rays are a type of electromagnetic wave with the ability to penetrate different objects. The atomic number and density of an object are the two main factors controlling the degree of photon absorption and penetration. This means that the photon penetration differs in different materials. A medium with a small atomic number and low density […]
X-ray Production (X-ray Tube)
After the discovery of X-rays by Wilhelm Röntgen in 1895, X-ray has been widely used in medicine, industry, and engineering. An X-ray production tube is an essential part of any X-ray imaging system. X-rays are produced when moving charged particles collide with a material (target) and are deviated from their original path, or a […]
How the cat knows what it’s smelling, discovering the secret to complex function of the cat’s nose structure using micro-CT
Micro-computed tomography (micro-CT) is an advanced and non-destructive imaging method that visualie the internal structure of objects in a three-dimensional manner similar to clinical CT scanning, but on a smaller scale and with very high resolution. Researchers can understand the functioning of complex structures in the body of living organisms such as mammals by imaging […]
Researchers Create Method to Detect Cases of Anemia in Archaeological Remains
Diagnosing anemia in living people is typically a matter of a routine blood test. Retrospectively diagnosing anemia in people who died decades or even centuries ago is much more challenging since there is no blood left to test. Anthropologists at McMaster University and the University of Montreal, working with a hematologist colleague, have overcome that […]
Mapping the Vagus Nerve: Researchers Look to Pave the Way for Bioelectronic Breakthroughs
Researchers have their sights set on creating a first-of-its-kind anatomical map of the vagus nerve. Stavros Zanos of the Feinstein Institutes for Medical Research is leading a three-year-long research study called Reconstructing Vagal Anatomy (REVA), along with collaborators at the Feinstein Institutes, the Zucker School of Medicine at Hofstra/Northwell Health, and Temple University. The NIH-supported […]
How can molecular micro CT imaging revolutionize drug discovery?
“Micro-CT imaging can revolutionize the quality of current drug discovery procedures, while it requires less labor and expertise.” Introduction In the pharmaceutical industry, the process of drug development is very expensive and time-consuming. Typically, the US $1–1.5 billion and several years are estimated to be needed for the development of a new drug before extensive […]
