This Model Digital Subtraction Angiography (DSA) Phantom† conforms to the recommendation in Report No. 15 by the American Association of Physicists in Medicine (AAPM) - Digital Radiology/Fluorography Task Group of the Diagnostic X-Ray Imaging Committee. 76 710
Benefits
Dramatic improvement in the quality of the subtracted image due to: - Improved phantom stability - Increased homogeneity of bone material in bone blocks
Eliminates occurrence of mis-registration artifacts caused by inadvertent movement of the phantom components during image acquisition
Features
New phantom design yields dramatic improvement in the quality of the subtracted image
Conforms to Report #15 by the American Association of Physicists in Medicine (AAPM)
Quantitatively measures high- and low-contrast spatial resolution
Retaining hasps ensure a tight fit between the step blocks, for reduced motion artifacts
Specially-designed “stop” on the end of the slot blocks improves the positional accuracy of the insert material during image acquisition, and reduces the number of DSA frames that must be acquired
The U-block provides a very sturdy support when entrance exposures are being measured with a dosimeter ion chamber
Two artery blocks in two concentrations of iodine: 15 mg/ml and 150 mg/ml, for increased clinical relevance
A 300 mg/ml iodine artery block is available as an option
