• Computed Radiography

  12/20/2010

  Computed Radiography, or CR uses very similar equipment to conventional radiography except that in place of a film to create the image, an imaging plate (IP) made of photostimulable phosphor is used. The imaging plate housed in a special cassette and placed under the body part or object to be examin..

• Medical Ultrasonography

  11/29/2010

  Medical Ultrasonography, or diagnostic sonography (ultrasonography) is an ultrasound-based diagnostic imaging technique used to visualize subcutaneous body structures including tendons, muscles, joints, vessels and internal organs for possible pathology or lesions. Obstetric sonography is commonly u..

• Magnetic resonance imaging

  11/16/2010

  Magnetic resonance imaging Magnetic resonance imaging (MRI), nuclear magnetic resonance imaging (NMRI), or magnetic resonance tomography (MRT) is a medical imaging technique used in radiology to visualize detailed internal structures. The good contrast it provides between the different soft tissues ..

• X-ray image intensifier

  9/9/2010

  An X-ray image intensifier (XRII), sometimes referred to as a C-arm x-ray unit or fluoroscopy in medical settings, is an imaging device which usesX-rays and produces a live image feed which is displayed on a TV screen. The term image intensifier refers to a special component of the machine, which al..

• Flat panel detector

  9/9/2010

  Flat panel detectors are a class of solid-state x-ray imaging devices similar in principle to the image sensors used in digital radiography and video, but due to the impracticability of focusing x-rays, the sensors are hundreds of times larger than those used in digital cameras. X-rays pass through ..

• CCD Detector

  7/19/2010

  A charge-coupled device (CCD) is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for example conversion into a digital value. This is achieved by "shifting" the signals between stages within the device one at a ..

• Components of X-ray machine

  7/1/2010

  An X-ray machine utilizes electromagnetic radiation to produce an image of an object, usually with the purpose of visualizing something located below the object's surface. An x-ray machine is made up of an X-ray source orX-ray tube, an x-ray detection system, and positioning hardware to align these ..

• X-ray generator

  6/22/2010

  X-ray generator is a device which supplies electric power to the X-ray tube and permits selection of X-ray energy (kVp), X-ray quantity (mA), and exposure time. The generator has three main interrelated electric circuits to serve three main functions: 1) The filament circuit supplies the power neede..

• X-ray tube

  6/18/2010

  An X-ray tube is a vacuum tube that producesX-rays. They are used in medical X-ray machines. X-rays are part of the electromagnetic spectrum, an ionizing radiation with wavelengths shorter than ultraviolet light. X-ray tubes evolved from experimental Crookes tubes with which X-rays were first discov..

• Radiography

  6/8/2010

  Description Medical radiography is a broad term that covers several types of studies that require the visualization of the internal parts of the body using x-ray techniques. For the purposes of this page radiography means a technique for generating and recording an x-ray pattern for the purpose of p..

• Types of Medical Imaging(2)

  6/2/2010

  Ultrasound Imaging Ultrasound waves have a frequency just beyond that of audible sound. Similar to sonar used by submarines, these waves are emitted and bounce back once they strike an object. As a clinical tool, ultrasound imaging (ultrasonography) can detect differences between solid and liquid ma..

• Types of Medical Imaging(1)

  6/1/2010

  Various imaging tests are available for diagnostic purposes. What are the different types of medical imaging？ Among the wide array of technologies in modern medicine, medical imaging is a major advancement. The ability to take pictures of the human body has many useful clinical applications. Differe..
