The Intricacies of MRI Magnets


26 May, 2011 | MRI

The MRI magnet is the largest and the most expensive component of the Magnetic Resonance Imaging System. The Three Main MRI Magnet Types In general, there are three main types of magnets used in MRI systems: resistive, permanent and superconducting. Resistive MRI magnets are wound around a cylinder and create a magnetic field when electricity [...]

CT Scanner Gantry Informational Guidelines


22 May, 2011 | CT Scanner

CT Scanner Gantry Basic Components The largest component of a CT scanner system is referred to as the scan or imaging system. The imaging system primarily includes the CT scanner gantry and patient table or couch. The CT scanner gantry is a moveable frame that contains the x-ray tube, including: collimators and filters, detectors, data [...]

CT Scanner X-Ray Tubes Clarified


15 May, 2011 | CT Scanner Parts

Improved Technologies Lead to Challenging Tasks for CT Scanner X-Ray Tubes. The most current CT scanning techniques place a high heat load on the CT scanner x-ray tube, due to the need for high tube current values to provide enough photons in the image, when scanning with fast rotations and fine slices. Increasing rates of [...]

The Evolution of CT Scanner Detectors


11 May, 2011 | CT Scanner

CT scanners are designed for imaging of the internal structures of the body. They provide detailed anatomical information by utilizing the principle that different types of tissue structures scanned are displayed in the image as different shades of grey. Intravenous or oral contrast media may be used to further enhance differentiation between tissues. The basic [...]

Diagnostic Ultrasound Imaging Technology


1 May, 2011 | Diagnostic Ultrasound

Diagnostic ultrasound is an ultrasound-based diagnostic medical imaging technique used to visualize muscles, tendons and many internal organs to capture their size, structure and any pathological lesions using real-time tomographic images. Ultrasound has been used by radiologists and sonographers to image the human body for many years and has become one of the most widely [...]
