X-ray C-Arm with Angiography Novarex NT-20

The Novarex NT-20 is an imaging system with a mobile C-shaped arm that meets modern growing demands for image quality while ensuring optimal results with minimal radiation exposure.

The device design is intended for use in various fields of medicine, including general surgery, intensive care, urology, orthopedics, emergency care, pain management procedures, as well as abdominal, thoracic, vascular, and neurosurgery.

Digital Subtraction Angiography (DSA) is an X-ray fluoroscopy technique used in interventional radiology to clearly visualize blood vessels within bone or soft tissue. Images are obtained using a contrast agent by subtracting a «pre-contrast image» (mask) from subsequent images taken after the contrast medium is introduced into the structure. This process gives the technique its name – «digital subtraction angiography.»

The image processing system supports digital zoom, edge and recursive filters, brightness and contrast adjustment, rotation, negative inversion, real-time data overlay, preset configurations, patient data registration, DICOM connectivity, print management with orientation and layout selection, preview, and sending of images to Windows.

Technical Specifications of Digital Subtraction Angiography (DSA)

• Real-time subtraction: 15 frames per second

• Image selection function for masking

• Landmark function: partial percentage subtraction

• Pixel shift: move the mask to match the image

• Stenosis calculation

• Full range of vascular measurements

• DICOM: archive, send, print, and query
