Dose, image quality and time are highly
interdependent. Traditionally, favoring one
often means sacrificing another. In systems
without Evolution technology, this can mean
that lowering dose requires a longer acquisition
time, which can be more taxing to patients
and result in motion artifacts. Likewise, reducing
time can require a higher dose to acquire a
suitable image.
With the Optima NM640, you can maintain high
image quality while reducing time or dose by up
to 50% in most procedures—without increasing
exam time.
low dose
Precise technology.
High-performance care.
For years, SPECT/CT has required clinicians
to make tradeoffs between dose and image
quality. Not anymore.
Thanks to GE Healthcare’s innovative
low-dose technology, the Optima NM/CT 640
delivers exceptional images at a low dose.
