Immobilizing pad suppressing motion artifact in abdominal intravenous digital subtraction angiography (IVDSA). A new device suppressing motion artifact in abdominal intravenous digital subtraction angiography (IVDSA) was made. It consists of a styrol foam pad and magic fastener bands. The styrol foam pad is fastened tightly to press the patient's upper abdominal portion by the bands. This device not only minimizes the motion artifact but improves image quality by decreasing the subject thickness.
