Those in the market for a refurbished Siemens CT scanner know there are multiple systems and to choose from. Between slice counts, cooling systems, and X-ray tube types, making a decision can seem daunting.
Below we'll give a side-by-side comparison of the Siemens Sensation CT and Siemens Emotion CT from slice count to patient volume needs.
& Siemens Emotion CT Compared
The Siemens Sensation series offers more slice count options. Systems are available in 4, 10, 16, 40, and 64-slice versions. The Siemens Emotion series comes in 1, 2, 6, and 16-slice versions.
Water vs. Air Cooling
All Siemens Sensation CTs are water-cooled and generally require an outdoor chiller. All Siemens Emotion CTs are air-cooled.
This difference gives the Sensation advantages in terms of system cleanliness and overall room noise. The Emotion has an advantage in terms of maintenance costs, as there are no chiller-related services needed.
Siemen Sensation scanners have a larger overall footprint than Siemen Emotion scanners. They also require some outside space for the placement of the chiller unit. Being smaller, the Emotion series is often a better pick for facilities with space constraints.
The Sensation series comes with either a Straton tube (8.0 MHU) or an Akron Q (5.3 MHU). The Straton (on some 16s, and all 40s and 64s) is very expensive to replace.
In comparison, the Akron Q (on 4s, 10s, and some 16s) costs much less.
The Emotion series uses Dura X-ray tubes.
The Dura 202 or 302 for single-slice units. The Dura 352 is for dual-slice, and the Dura 422 is for 6 and 16-slice scanners. The Dura 422 costs more to replace than an Akron Q, but still considerably less than a Straton.
Sensation series scanners have an advantage in working in high-volume facilities. This is because their X-ray tubes have a higher heat capacity.
If your facility has a more moderate patient volume level, an Emotion scanner can save you both money and space.
Both of these series began manufacture in 2000; the Sensation at the 4-slice level and the Emotion at the single-slice. The Emotion 16-slice version arrived a couple of years after the Sensation 16.
If you polled 100 Siemens CT users on which of these scanners is better, I suspect the results would be 50/50. Which CT you choose will depend on your site’s specialties, available space, and patient volume.
