Gemstone Spectral Imaging (GSI) improves image quality over conventional imaging techniques due to higher contrast to noise ratio (CNR), reduced beam hardening artifacts, enhanced material separation, and quantitative material information all at a full 50cm field of view.
GSI provides information about the chemical composition of body materials, allowing the user to separate calcium, iodine and water to aid in the characterization of pathology.
A new spectrum of information and abilities across areas of clinical diagnosis including:
- Quantitative lesion characterization
- Beam hardening reduction
- Enhancing contrast quality with monochromatic spectral image
- Virtual non contrast like images
- Enhanced coronary visualization in the presence of calcification
- Beam hardening reduced myocardial perfusion assessment
GSI is a unique dual energy technique that uses rapid kV switching and Gemstone Detector technology to acquire and generate material density data. Both high and low energy data sets are acquired simultaneously for near perfect anatomical registration throughout the full 50cm field of view.
This data can be used to separate materials and derive monochromatic spectral images using a projection-space reconstruction algorithm.
GSI provides information about the chemical composition of body materials. This capability enables the user to easily separate calcium, iodine and water to aid in the characterization of pathology.
Gemstone Spectral Imaging can subtract iodine from images to generate a virtual non
