The revenue per study from a SOMATOM Definition AS is the same as from a more recent 64-slice system when the protocol types are equivalent. That arithmetic is why the Definition AS persists in the secondary market as a viable acquisition: it handles a broad clinical protocol range, reimbursement is based on study type not scanner vintage, and the pre-owned acquisition cost leaves room for the monthly payment to fit within operating cash flow at even moderate scan volumes. For an imaging center that values proven Siemens SOMATOM engineering and an established secondary service market over latest-generation features, the Definition AS checks the right boxes.
We structure SOMATOM Definition AS financing through pre-owned loan and lease channels. Most transactions in this platform's secondary market price range qualify for application-only financing, which delivers fast credit decisions without requiring financial statements. For larger transactions or more complex credit scenarios, full-doc options are available with our financing desk.
Definition AS Specifications and Use Cases
Siemens produced the SOMATOM Definition AS in multiple configurations, most commonly in 64-slice and 128-slice variants, the latter marketed as the Definition AS+. Both use a single X-ray source, distinguishing them from the dual-source Definition Flash and Definition DS. The 64-slice version covers standard CT protocols adequately; the 128-slice AS+ adds detector coverage for more demanding applications including cardiac CTA in selected patients and multi-phase oncology studies.
Key technical features that remain clinically relevant: SAFIRE iterative reconstruction supports dose reduction protocols across study types. The wide-bore option on some Definition AS configurations expands the patient population the scanner can accommodate, including bariatric patients and radiation therapy simulation positioning. Oncology centers performing simulation CT alongside diagnostic imaging sometimes value the wide-bore capability as much as the slice count.
- 64-slice base configuration; 128-slice Definition AS+ variant also available
- Single X-ray source with fast rotation capability for general CT protocols
- SAFIRE iterative reconstruction for dose reduction
- Wide-bore option available on some configurations
- Established secondary market with Siemens ISO service coverage available in most regions
Definition AS Pricing and Financing Terms
Pre-owned SOMATOM Definition AS units in good condition typically price between $80,000 and $250,000, with the 128-slice AS+ commanding premiums over the standard 64-slice version. Wide-bore configurations also command a premium based on the additional clinical utility they provide. At these price points, transactions regularly fall within the application-only threshold.
Terms of 36 to 60 months are typical. Shorter terms make more financial sense for older units where the remaining useful service life should inform the financing period. A 60-month term on a unit that is 10+ years old and has significant tube hours creates a mismatch between the financing obligation and the scanner's expected operational life. We discuss this tradeoff with buyers before finalizing term length.
For buyers considering the Definition AS against a newer single-source platform like the SOMATOM go.All, the pre-owned Definition AS's lower acquisition cost often produces a lower monthly payment at equivalent term length, which can matter for facilities where cash flow management is the primary financing driver.
Pre-Owned Definition AS: Evaluation Checklist
All SOMATOM Definition AS acquisitions today are pre-owned. When evaluating a specific unit, buyers should confirm:
- Tube utilization in mAs: remaining tube life directly affects clinical uptime and financing advance rate
- Software build version: confirm SAFIRE and any dual-energy software packages are active on the specific unit
- Service record completeness: gantry PM, detector calibrations, and any hardware replacements documented
- Wide-bore configuration: verify bore diameter and confirm the patient table supports wide-bore positioning
- Parts availability: confirm with the potential ISO or Siemens service team that parts for the specific unit's vintage are available
Buyers sourcing from dealers who provide warranty and reconditioning documentation are in a stronger position than buyers sourcing from private parties without documentation. For private-party transactions, we facilitate private-party purchase financing but recommend a pre-purchase inspection from an independent service technician before committing to price.
Best Buyers for the Definition AS Today
The SOMATOM Definition AS continues to serve facilities where clinical need is broad but budget is constrained. Radiology groups opening satellite imaging locations, community hospitals replacing first-generation 16-slice systems, and outpatient centers establishing CT capability for a specialty practice all find the Definition AS at a price point that matches the business case without requiring premium platform investment.
For facilities where a wide-bore configuration is specifically needed, such as oncology centers doing simulation CT or centers serving a bariatric patient population, confirming the bore diameter of any specific unit before purchase is essential. Not all Definition AS units are wide-bore, and the clinical requirement should drive the search to the right configuration rather than adapting the workflow to a standard-bore unit.

Questions
What is the difference between the SOMATOM Definition AS and the Definition AS+?
The Definition AS is typically the 64-slice single-source version; the Definition AS+ is a 128-slice variant with additional detector coverage. The AS+ handles more demanding protocols including cardiac CTA in a broader patient population and provides larger z-axis coverage per rotation for multi-phase oncology and vascular studies. The AS+ typically commands a price premium in the secondary market.
Can I finance a SOMATOM Definition AS with past credit issues?
B/C credit financing is available for medical equipment transactions at this price point. The rate will be higher than for prime credit applicants, and a down payment may be required. Send us the details of your situation and we will be honest about what the market will bear for your specific credit profile.
How does SAFIRE reconstruction compare to current ADMIRE?
SAFIRE is Siemens' earlier iterative reconstruction algorithm, available on definition-generation systems. ADMIRE is the current implementation on go-line and higher systems, generally offering better noise reduction at equivalent dose levels. For most routine clinical protocols, SAFIRE's dose reduction capability remains diagnostically acceptable. ADMIRE's advantage is more pronounced in demanding dose-reduction scenarios.
Can I bundle room modification costs into the Definition AS financing?
Room modification and shielding costs can be included when they are part of the initial transaction and documented on invoices at the time of purchase. The total project cost including soft costs should be discussed with us before purchase so we can confirm the lender's willingness to include them in the advance.
Is the SOMATOM Definition AS a good stepping stone before investing in a newer Siemens platform?
For facilities building a referral base and proving scan volume before committing to a premium platform, yes. A Definition AS acquisition on a 36 to 48-month term positions the facility to come off the obligation and upgrade to a current-generation system at a point when referral volume and cash flow support the higher investment. This staged approach is common among growing imaging centers.
