Configuration for Vascular and Superficial Work

Vascular and superficial requirements in primary care fall mainly into three groups: carotid screening, superficial organs, and vascular access or needle guidance. The configuration can be set from those three.

1. Carotid and limb vessels: linear array 7.5–10.0 MHz, with Color, PDI and PW flow functions. The carotid runs deeper, so the probe must be able to switch to a deeper setting.

2. Thyroid, breast and lymph nodes: a high-frequency linear array at 10.0–14.0 MHz gives clearer superficial detail.

3. Vascular access and needle guidance: high-frequency linear array with in-plane and out-of-plane needle modes, used with a sterile probe cover.

4. Skin and very superficial structures: dermatological ultrasound requires a 16.0–20.0 MHz or higher probe, and can be configured according to need in primary care.

Suggested primary-care configuration: one 7.5–10.0 MHz linear array is essential; a 10.0–14.0 MHz high-frequency linear array is a bonus. They need not be bought together — fit the first one.

Vascular and superficial imaging places high demands on technique, so once the equipment is in place, training matters more than upgrading.
