Image quality factors

  • Transducer technology and frequency range.
  • Beam-forming and processing power of the platform.
  • Presets tuned for your exam types.
  • Screen size and quality for reading fine detail.

Software that saves time

  • Specialty measurement and report packages.
  • Automatic measurements (for example follicle counts or cardiac function) on higher-end systems.
  • DICOM export and PACS connection.
  • Remote service and software updates.

Frequently asked questions

What is a USG machine?
USG stands for ultrasonography. A USG machine is the same as an ultrasound machine.
What ultrasound machine does an O&G clinic need?
Usually a cart-based system with a volume convex probe for 3D/4D, an endocavity probe, obstetric growth tables and Doppler.
Can one ultrasound machine cover several specialties?
Yes, a general-imaging platform with several probes covers most clinic needs. Specialist cardiac or high-end obstetric work benefits from a system designed for it.
