XF7800 color doppler ultrasound system adopts the imaging technology of pioneer high-end
products, with excellent image quality, efficient operation flow and high cost performance,
which can meet the extensive clinical diagnosis needs and create greater value for hospitals.
Humanized ergonomic design
• a 15-inch LCD display that rotates up and down, left and right
• compact fuselage, easy to move
• flexible lifting panel
• two-level backlit keyboard, more convenient to operateIt can meet the needs of clinical diagnosis and improve
the confidence of diagnosis
.• broadband frequency shift harmonic imagingIt can effectively reduce noise and improve contrast resolution
• intelligent speckle noise suppression imagingIntelligent speckle noise suppression technology can intelligently
identify different tissue information in different spatial dimensions, inhibit the display of speckle noise edge
information, and make the image more exquisite.
• intelligent space composite imagingIntelligent spatial composite imaging technology, through
spatial multi-angle deflection scanning, updates echo signals received from different angles
in real time, continuously updates fusion imaging, effectively inhibits random noise and
clutter signals under the premise of guaranteeing the temporal resolution, enhances the
target organization display, and improves the spatial resolution of the image.High resolution
medical liquid crystal display
• flexible adjustment of control panel
