MRI systems utilize a combination of advanced magnet and radio wave technology to produce images based on the characteristics of hydrogen nuclei within tissues in the human body. ContextVision is continuously developing image enhancement and image analysis applications to improve the diagnostic value of MRI imaging.
Ultrasound systems capture the reflection of a sound wave as it is reflected by biological tissue. The resulting reflection pattern is converted into diagnostic information via a hand-held ultrasound transducer passed over the anatomy being imaged, and processed by the ultrasound machine.
Ultrasound imaging is favored for studying soft-tissue organs in the chest and abdomen, and for investigating blood flow through the heart and blood vessels. The diagnostic value and imaging data is immediately presented in Real Time. The transition from analog to digital technology is starting to provide greater opportunities to advance image processing in ultrasound equipment, allowing advanced image enhancement to reduce noise and speckle.
The digitalization of ultrasound systems has also opened up possibilities for demanding and difficult image analysis applications, such as the assessment of blood perfusion in the heart muscle.
X-ray is a general term that applies to a broad spectrum of imaging techniques that utilize X-rays to provide diagnostic information. An X-ray image is produced by sending radiation through the body and registering differences in absorption on a film or a detector. The introduction of indirect and direct digital systems has facilitated the utilization of advanced image enhancement.
CT systems consist of one X-ray source and 16, 32, 64, or even higher numbers of detector arrays, mounted on a circular gantry which rapidly rotates around a patient. During CT scanning, the attenuation of X-rays from various directions is recorded and converted to projections of the linear attenuation coefficient distribution of the patient. Two- or three-dimensional images are reconstructed from these projections.
CUSTOMIZED APPLICATION SOFTWARE
ContextVision has a broad-based application experience and have developed a large number of commercial systems and software products. As a partner, ContextVision can take full project responsibility from start to finish. Feasibility studies are easily made through a flexible internal image analysis platform. Using the elaborated toolbox, customized image processing is possible without initial implementation in the customer's hardware/software.
