Frequently Asked Questions

What is the Philips S4‑2 Compact ultrasound probe used for?

The Philips S4‑2 Compact ultrasound probe is a phased array diagnostic transducer used for imaging the heart (cardiology), brain blood flow (transcranial Doppler), and obstetric/gynecologic structures. It excels in deep tissue visualization due to its 2.0–4.0 MHz frequency range.

Is this probe new or refurbished?

This product is brand new and original (OEM) from Philips, tested in an ISO 13485 certified probe laboratory, and includes warranty coverage.

Which ultrasound machines are compatible with the S4‑2 Compact transducer?

This diagnostic ultrasound transducer is compatible with major Philips platforms, including the EPIQ, Affiniti, CX50, and Sparq systems. If you use a different model, we can verify compatibility.

What frequency does this transducer operate at?

The Philips S4‑2 Compact transducer operates between 2.0 and 4.0 MHz, providing a balance of penetration and resolution ideal for multiple clinical applications.

Can this probe be used for pediatric imaging?

Yes. While primarily designed for adult cardiac, transcranial, and OB/GYN imaging, this probe’s frequency and phased array design can support pediatric scans where deeper penetration and dynamic imaging are needed.

What makes the S4‑2 Compact better than a linear or convex probe?

Phased array probes like the S4‑2 Compact are specifically designed for:

• Rapid electronic steering
• Small footprint for intercostal imaging
• Deeper tissue visualization

In contrast, linear probes have narrower depth and convex probes may lack the frame rates needed for dynamic cardiac studies.

How should I maintain this ultrasound transducer?

To maintain optimal performance:

• Clean and disinfect according to Philips guidelines
• Avoid sharp bends in the cable
• Store with protective cap when not in use
• Schedule periodic performance testing

Can this probe be used for Doppler studies?

Yes. The S4‑2 Compact is suitable for both color Doppler and spectral Doppler when used with compatible ultrasound systems.

Who should purchase this product?

This transducer is ideal for imaging professionals and healthcare facilities that require high‑quality, versatile diagnostic ultrasound probes for cardiac, OB/GYN, and neurovascular applications.
