Back in 2005, the performance of Siemens
wide-bore magnets took the industry by storm. In
fact, when 70 cm and closed-bore magnets were
compared, the Siemens Espree was hands-down the
winning option. Flash forward 19 years later and
the Siemens Aera is now the talk of the town
among closed-bore magnet buyers. Is the Aera a
profound transformation or just an incremental
improvement? Lets take a closer look. First,
lets look at the similarities between the two
models.

• Both offer greater patient comfort
• Both have Total Imaging Matrix technology that
  lets you combine coils to image multiple regions
  of the body at the same time, which eliminates
  having to change out coils
• TIM reduces total scan time
• You can image over a larger areas without moving
  the patient when you use TIM
• Both use the Syngo platform

• What are the differences between Siemens Espree
  and Aera?
• The Siemens Espree has one table type. Its a
  fixed table that hangs off the front of the
  gantry and doesnt make contact with the floor.
  The Aera is available in both a floor-mounted and
  roll-away configuration so you can choose
• The Esprees components for transmitting and
  receiving RF signals are in the equipment room
  while the Aeras are mounted adjacent to the
  magnet
• The Aera has less cabling and less noise, which
  provides a better signal quality
• While both have TIM, the Aera has TIM 4G, the
  latest iteration. This offers added coil elements
  and an exceptional signal-to-noise ratio

• The Aera has a slightly higher gradient class
• The Espree uses an older version of TIM. The TIM
  4G Aera uses coils with up to 64 independent RF
  channels and increases to 204 when coils are
  combined. You get faster acquisition and better
  image quality with the Aera
• The Espree has an elliptical field when the Aera
  shims to a spherical magnetic field. The Aeras
  field more closely aligns with the overall shape
  of the human body
• You can easily find the Espree on the secondary
  market while the Aera isnt widely available yet
• The Espree is less costly than the Aera
