6. The system starts acquiring the image “Mask” at this time the kV/mA is locked
7. After the “Mask” is acquired, the system displays the real-time image on the reference
display monitor. The subtracted image will be displayed on the live display monitor. When
the DSA image is displayed on the live monitor, Operator starts injection and the display
shows the contrast media as it is injected. The system will capture at the selected or default
rate.
9. When you have obtained the desired imaging, release the hand or foot switch. The acquired
images will automatically replay in a continuous loop, until you either exit DSA or start a
new acquisition. This takes a few seconds to start the replay.
10 To exit DSA mode, press either the DSA button again on the DeskView Control Panel, or
press one of the Fluoroscopic mode buttons.
Only the subtracted image will be displayed during capture and replay. The user cannot remove
the mask from the DSA.
To change the capture or replay rate use the Frame Rate
utton to
change from 1 to 15 f/sec
NOTE:
During acquisition, image intensity and contrast looks different than during normal
fluoroscopy and is normal for the images to look this way. The contrast and brightness
and Gamma curves are set to provide
etter visualization of the contrast media during the
image capture in DSA.
NOTE:
All Cine/DSA Image Acquisitions are Protected. The ZIEHM QUANTUM protects all
sequential image acquisitions (DSA, Cine Studies) are automatically stored to the Hard
Drive for immediate review of the image sequences or can be recalled at a latter time.
NOTE:
When performing DSA image acquisitions it is important to make sure the patient does
not move. The motion of the patient will disrupt the image quality.
9.4 STORING OF DSA/CINE IMAGES
The system will automatically stores the entire dynamic image acquisition to the hard drive
therefore the operator is not required to select a storing method for the DSA or Cine image
sequences.
