QUESTIONS AND ANSWERS

QUESTION: On page 4 under “Gradient System” the standard strength is listed at 35 .. is this a typo? Generally, the strength and stew rate are at 33120. I just want to clarify if this was a misprint or not.

ANSWER: Every gradient system is characterized by its degree of linearity, maximum amplitude (strength, measured in mT/m), and rise time (i.e., slew rate, measured in T/m/sec).

The SOW required that the strength is 35 (must have been a typo, should be 33), but it’s not unreasonable to require such (our new Signa Artist will have a strength of 45 mT/m at 200T/m/sec! – this is today’s standards). These factor impact the speed of imaging.

Included the strength and slew rate of some 1.5T MRI systems below.

The question above states a measurement of “33120” which refers to a standard strength in the z-axis of 33 mT/m and a slew rate of 120 T/m/sec, which one be the GE Signa Creator or GE Signa Explorer below.

GRADIENT SYSTEM

QUESTION: On page 13 the solicitation has the Gray Market Prevention Language - Are you wanting to lease a brand-new machine for only 4-6 months? I ask this because we have an MRI that is fully remanufactured and certified through the OEM. Would this be acceptable?

ANSWER: There is no brand-new system that can be outfitted into a trailer for our purpose. Almost mobile MRI are “pre-owned” or “repurposed”. We do require OEM parts for repairs.
