Philips Affiniti 70 Review: Premium Imaging at a Competitive Price
If you run a mid-size clinic or imaging center and you're tired of choosing between image quality and budget, the Philips Affiniti 70 deserves a serious look. It sits in that sweet spot where you get flagship-level PureWave transducer technology without paying flagship prices. We spent considerable time evaluating this system configured with the C6-2 curved array, L9-3 linear array, and PureWave OB/Vascular transducers — the exact bundle most general and OB/GYN practices need.
Product Overview
The Philips Affiniti 70 is a shared-service ultrasound platform built on Philips' EPIQ architecture but positioned as a more accessible option for practices that need excellent image quality across multiple clinical applications. It launched as part of the Affiniti series, which Philips designed to bridge the gap between their entry-level ClearVue line and the premium EPIQ 7.
Key specifications:
- Platform: Affiniti series, shared-service
- Display: 21.5-inch LED monitor with adjustable arm
- Transducer ports: 4 active ports
- Imaging modes: 2D, M-Mode, Color Doppler, Power Doppler, PW/CW Spectral Doppler, Harmonic Imaging
- Technology: PureWave crystal technology, SonoCT real-time compound imaging, XRES adaptive image processing
- Dimensions: Compact cart-based form factor (~160 lbs)
- Applications: Abdominal, OB/GYN, Vascular, Small Parts, MSK, Cardiac (with optional transducers)
This particular configuration — the C6-2, L9-3, and PureWave OB/Vascular transducers — covers abdominal, obstetric, gynecological, vascular, and superficial imaging. It is essentially a workhorse setup for general imaging practices.
Hands-On Experience
Initial Setup and Workflow
The Affiniti 70 boots in under 60 seconds, which is noticeably faster than older Philips systems like the Philips HD11 XE. The touchscreen interface is intuitive — Philips carried over the gesture-based controls from the EPIQ line, so pinch-to-zoom and swipe navigation feel natural if you've used a modern tablet.
Switching between transducers is seamless with four active ports. We found ourselves swapping between the C6-2 and L9-3 mid-exam without any meaningful delay. Presets load quickly, and customizing them to your preferences takes minutes, not hours.
The C6-2 Curved Array
The C6-2 is the primary abdominal and OB transducer in this bundle. It operates at 2-6 MHz and delivers solid penetration on larger patients while maintaining good near-field resolution. For routine abdominal scans — liver, gallbladder, kidneys — the image quality is a clear step above what you get from budget systems. The harmonic imaging mode cleans up image artifacts noticeably on patients with higher BMI.
For OB work, the C6-2 paired with Philips' SonoCT compound imaging produces smooth, detailed fetal anatomy views. The auto-measurement tools for biometry are accurate and save time during routine second-trimester scans.
The L9-3 Linear Array
The L9-3 covers 3-9 MHz and handles vascular, thyroid, breast, and musculoskeletal imaging. In our experience, this is where the Affiniti 70 really shines compared to competitors in its price range. The lateral resolution on superficial structures is impressive — thyroid nodules as small as 2-3mm are clearly delineated. For vascular work, color Doppler fills well and the spectral tracings are clean with minimal noise.
If your practice handles carotid studies, DVT assessments, or any peripheral vascular work, the L9-3 performs at a level that rivals systems costing significantly more.
PureWave OB/Vascular Transducers
PureWave is Philips' single-crystal transducer technology, and it's the headline feature that separates the Affiniti 70 from its more affordable competitors. Single-crystal elements produce wider bandwidth and improved sensitivity compared to traditional ceramic elements. The practical result: better penetration on difficult patients and finer resolution across the entire imaging depth.
For OB/GYN applications, the PureWave transducer delivers noticeably better image quality on second and third-trimester scans, especially on patients where conventional transducers struggle. Vascular imaging benefits similarly — you see cleaner vessel walls and more reliable Doppler signals in deep vessels.

Who Should Buy This
- General imaging practices that perform abdominal, OB/GYN, and vascular studies daily and need reliable, high-quality output across all three
- OB/GYN clinics upgrading from entry-level systems that want PureWave image quality without the EPIQ price tag
- Vascular labs looking for clean Doppler performance in a shared-service platform they can also use for abdominal work
- Practices buying used/refurbished — the Affiniti 70 holds up well on the secondary market, and the C6-2/L9-3 bundle is the most common configuration available
Who Should Skip This
- Practices needing dedicated cardiac imaging — while the Affiniti 70 can do basic cardiac work with the right transducer, a dedicated cardiac ultrasound system like the EPIQ 7C or GE Vivid series is a better choice for echo-heavy workloads
- Mobile or point-of-care users — at 160 lbs on a cart, this is not a grab-and-go system. Look at the Philips Lumify or SonoSite Edge II for bedside and field use
- Clinics on extremely tight budgets — if you need a functional ultrasound under $10,000, refurbished systems from the previous generation (HD11 XE, iU22) offer more value at that price floor

Frequently Asked Questions
How does the Philips Affiniti 70 compare to the EPIQ 7?
The EPIQ 7 is Philips' flagship and offers nSIGHT imaging, anatomical intelligence, and a broader transducer ecosystem. The Affiniti 70 shares PureWave technology and much of the software architecture but lacks the most advanced processing features. For general imaging, the difference is noticeable but not dramatic. For research or high-volume echo labs, the EPIQ 7 is the better choice.
Can the Affiniti 70 do 3D/4D imaging?
Yes, but it requires a compatible 3D/4D transducer (like the V6-2 or 3D9-3v), which is not included in the C6-2/L9-3 bundle. Adding a 3D transducer typically costs $3,000–$8,000 on the used market.
What is PureWave technology and why does it matter?
PureWave uses single-crystal transducer elements instead of traditional piezoelectric ceramic. Single crystals produce wider bandwidth — meaning better resolution at depth and improved sensitivity. The practical benefit is cleaner images on technically difficult patients (high BMI, deep structures) where conventional transducers produce noisy or degraded images.
Is the Affiniti 70 suitable for a veterinary practice?
Yes. The C6-2 and L9-3 transducers cover the frequency ranges needed for most large and small animal imaging. Several veterinary clinics use the Affiniti series as their primary diagnostic ultrasound. Check our guide to buying used ultrasound equipment affordably for tips on sourcing veterinary-appropriate systems.
How much does a Philips service contract cost for the Affiniti 70?
Annual service contracts from Philips typically run $3,000–$7,000 depending on coverage level (parts only vs. full service). Third-party service providers often offer comparable coverage for 30-50% less. Factor this into your total cost of ownership.
What transducers are compatible with the Affiniti 70?
The Affiniti 70 supports a wide range of Philips transducers including the C5-1, C9-2, L12-5, S5-1 (cardiac), 3D9-3v, and more. This makes it a flexible platform that can grow with your practice as you add clinical applications.
Final Verdict
The Philips Affiniti 70 with C6-2, L9-3, and PureWave OB/Vascular transducers is one of the strongest mid-range ultrasound systems available today, especially on the used market. It delivers image quality that competes with systems costing twice as much, handles the most common clinical applications with ease, and runs on a modern, efficient interface. If your practice needs a reliable shared-service platform for abdominal, OB/GYN, and vascular imaging, this configuration is hard to beat for the price. ```
