• Probe types supplied, such as convex, linear, endocavity and cardiac, and their frequencies.
• Image quality, software packages, storage and DICOM support.
• Safety features, power backup and a stabiliser.
• Installation, operator training, warranty duration, probe warranty, AMC and a GST invoice.

Who buys them

Hospitals, nursing homes, diagnostic centres, clinics, NGOs and government health facilities.

Frequently asked questions

Which probes should I order first?

A convex probe is the usual starting point for abdominal work, with a linear probe for superficial structures. Add others based on the specialities you plan to serve.

Do I need registration before buying?

Yes, registration under the PCPNDT Act is required for the facility using the machine, so complete it early. Suppliers often ask for the registration certificate before delivery.

Is a portable unit enough for a clinic?

Often yes for routine use, but check the probe range and image quality. Common brands include GE, Philips, Samsung, Mindray and Siemens.
