Siemens Antares Ultrasound System Review: Still Worth It in the Refurbished Market?
If you're equipping a clinic, imaging center, or teaching lab on a controlled budget, the refurbished ultrasound market can be overwhelming. Dozens of platforms compete for your attention, and separating genuine workhorses from overpriced obsolescence is harder than it looks. The Siemens Antares sits firmly in "former flagship" territory — and that legacy cuts both ways.
We've evaluated the Antares across clinical imaging demands, transducer compatibility, long-term serviceability, and real-world refurbished pricing to give you a clear picture of whether this system still deserves floor space in your facility.
Product Overview
The Siemens Antares is a premium cart-based diagnostic ultrasound platform released by Siemens Healthcare (now Siemens Healthineers) in the mid-2000s. Designed for high-volume, multi-specialty imaging environments, it was positioned as Siemens' flagship general-purpose system for its era — competing directly with the GE LOGIQ 9 and Philips iU22.
Key specifications:
- Form factor: Cart-based, mobile console
- Imaging modes: B-mode, M-mode, Color Doppler, Power Doppler, Pulsed Wave Doppler, Continuous Wave Doppler, Tissue Harmonic Imaging
- Proprietary technology: eSie (electronic Steer in Every direction) beam steering; eHD (enhanced Harmonic Detection)
- Applications: Radiology, OB/GYN, vascular, cardiac, musculoskeletal, small parts
- Connectivity: DICOM 3.0, network integration
- Transducer ports: Multiple active probe ports
On the refurbished market, the Antares typically sells between $300 and $900, depending on condition, included probes, and seller certification level — making it one of the more accessible ex-premium platforms available today.
Hands-On Experience
Initial Setup and Workflow
The Antares uses a conventional cart layout familiar to any sonographer trained in the 2000s. The control panel is comprehensive but not intimidating — physical knobs and buttons dominate, which many experienced clinicians prefer over touch-only interfaces. Boot time is typical of the era: allow 2-3 minutes from cold start to scan-ready state.
Transducer swapping is straightforward. The system supports a broad library of Siemens-compatible probes spanning linear, convex, phased array, and endocavitary configurations. If you're sourcing probes separately through the refurbished market, verify compatibility codes carefully, as not all Antares probes are cross-compatible with later Siemens platforms.
Image Quality
This is where the Antares earns its reputation. The eSie beam steering technology meaningfully improved near-field and off-axis resolution compared to contemporaries, particularly in vascular and musculoskeletal imaging. Tissue Harmonic Imaging (THI) remains clinically useful for abdominal and OB imaging in patients where acoustic windows are challenging.
Color Doppler sensitivity is strong. Clinicians who used this system in its prime consistently describe the Doppler performance as one of its standout traits — and on a well-serviced unit, that capability holds up.
The honest caveat: compared to modern systems with AI-assisted image optimization, beamformed GPU rendering, and automated measurements, the Antares requires a more experienced sonographer to extract the best images. This is not a plug-and-scan platform for newer staff.
Durability and Build
The Antares was built to Siemens' commercial-medical grade standards — heavy, solid, and designed for daily clinical throughput. On refurbished units in good condition, the mechanical components (wheels, articulating arm, probe ports) are typically still serviceable. Fan noise and occasional display aging are the most common wear issues reported on older units.
Pros and Cons
Pros:
- Exceptional image quality for its class, particularly in Doppler and harmonic imaging
- Broad transducer library with wide clinical application coverage
- DICOM 3.0 integration for PACS workflows
- Very competitive refurbished price point ($300–$900)
- Established service infrastructure — parts and technicians are available
Cons:
- No modern AI-assisted tools or auto-optimization features
- Larger footprint; not suitable for point-of-care or bedside-only workflows
- Software updates are no longer supported by Siemens Healthineers
- Older display technology may show aging on high-hour units
- Requires experienced sonographers to maximize output — steep learning curve for new grads
- Refurbished units vary widely in condition; always request service history

Who Should Buy the Siemens Antares
The Antares is a strong fit for:
- Teaching hospitals and university programs that need a full-featured diagnostic platform for training sonographers — the manual control interface is pedagogically valuable.
- Established radiology or vascular practices adding a secondary suite on a budget, where experienced staff can operate it without a learning curve.
- Medical equipment resellers and refurbishers looking for a reliable, high-image-quality platform with an established parts ecosystem.
- Veterinary imaging clinics with staff trained on human-medicine ultrasound — the Antares adapts well to large-animal and specialty small-animal applications.
Who Should Skip the Siemens Antares
Pass on the Antares if:
- You need point-of-care or portable capability — this is a dedicated cart system only.
- Your staff is predominantly early-career sonographers who rely on AI-assisted guidance and auto-optimization.
- You require active manufacturer support, software updates, or warranty coverage from Siemens.
- You're in a high-volume outpatient setting where turnaround speed and automation matter more than image ceiling.
- 3D/4D imaging is a primary clinical need — the Antares' 3D capabilities are limited compared to dedicated 3D/4D ultrasound machines available today.
Alternatives Worth Considering
1. GE LOGIQ P6 (Refurbished)
A strong alternative in the same refurbished price tier. The LOGIQ P6 offers comparable general imaging performance with a slightly more modern workflow interface. Probe compatibility across the GE ecosystem is broad, and the service network is well-established. Pricing is comparable to the Antares.
