Ludlum Medical Physics Model L-629
Rotating Spoke Test Tool
Introduction
The Ludlum Model L-629 Rotating Spoke Test Tool is
designed to evaluate the performance of the Fluoroscopic Imaging Systems.
The tool demonstrates screen image lag, motion blur, contrast, and related
distortions encountered in fluoroscopic examinations. **
When combined with aluminum or acrylic block
attenuators, the Rotating Spoke Test Tool provides the user with a means to
simulate the movement of guide wires and radiopaque catheters, seen in
Angiography or Cardiac Cath patient procedures.
The Rotating Spoke Test Pattern consists of a circular
5.5 inch diameter acrylic disk with steel 12 wires arranged on its surface
in 30 degree intervals. The wire diameters range from 0.02” to 0.005”.
There are two wires of each size directly opposite each other on the disk.
Lead numbers (1-6) appear on each half of the disk near the perimeter. The
disk is mounted on a synchronous motor with a speed of 30 RPM to simulate
movement of wires.
The visibility of smaller diameter wires ( 0.014” or
less) will confirm the system performance. [0.14” is a common guide wire
size]
