An ultrasound scan is a device that uses high-frequency sound waves to create images of the inside of the body. The scans are used to assess soft tissue structures, including muscles, blood vessels, the heart and various organs.

Besides the routine ultrasound scan, the unit also provides Doppler services which is a complex ultrasound examination involving careful analysis and evaluation of blood vessels such as venous doppler, renal artery doppler, carotid artery doppler and so on.


Ultrasound unit consists three 2D and a portable ultrasound machine manned by two senior ultra-sonographers. In addition to providing routine ultrasound services such as hepatobiliary (HBS), kidney-ureter-bladder (KUB), pelvic, obstetric scans and so on, the ultrasound unit provides Doppler services such venous doppler, renal artery doppler, carotid doppler to name a few. The unit also aids physicians with image-guided intervention.

Routine ultrasound services are available from 9 am to 3pm on weekdays and 9 am to 1 pm on Saturday. However, the emergency services are provided 24×7 on on-call basis.

Normally the ultrasound examination is performed on the spot itself if the patients are prepared. Otherwise an appointment is given from the ultrasound unit along with instruction on preparation.


Currently we have four machines as follows:

  1. Mindray with Doppler facility (2 numbers)
  2. GE Logic  with color Doppler facility
  3. GE Portable ultrasound machine

  • Hepatobiliary system (HBS)
  • Kidney, ureters and bladder (KUB)
  • Adrenals
