What is it indicated for?
The purpose of the ATD-T is to provide interface and support functions to allow
the use of Medrad disposable endorectal coils with the GEMS Signa 1.5 Tesla
MRI Scanner System and Torso Array Coil. The use of the ATD-T is a
requirement whenever MR imaging is to be performed using the GEMS Signa 1.5
Tesla MRI System with the Torso Array Coil and any of the Medrad family of
disposable endorectal coils. Use of the ATD-T is indicated with all 1.5 Tesla
Endorectal Coils.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
