Flouroscan® Mobile C-Arm Imaging System

Hologic was in the process of troubleshooting some rotational and positioning issues with their signature Flouroscan® mobile c-arm imaging system, when they approached Cooper Perkins with a couple redesign challenges: high operating forces when in lateral position and a distinct clicking sound during rotation.

After observing and analyzing the behaviors of the c-arm at various positions, the team at Cooper Perkins identified several areas of concern implicated in the looseness of the c-arm within its guide rollers. This looseness was also the likely cause of the noise and high friction experienced during use.  To solve these issues, Cooper Perkins recommended changes and adaptations to the roller material and diameter, contact area with radial roller, fit and tolerance of roller stack-up, and adjustment features.
