USG may refer to:
1.Universal Charging System,or Universal Charging Solution,an agreement on requirements for a common External Power Supply within Open Mobile Terminal Platform.
2.Medical ultrasonography,an ultrasound-based diagnostic imaging technique used to visualize internal organs.
3.Urine specific gravity (kidney),a measure of urine concentration or relative density

In physics,'ultrasound' refers to sound waves with a frequency too high for humans to hear.Ultrasound images (sonograms) are made by sending a pulse of ultrasound into tissue using an ultrasound transducer (probe).The sound reflects (echoes) from parts of the tissue; these echoes are recorded and displayed as an image to the operator.
Many different types of images can be formed using ultrasound.The most well-known type is a B-mode image,which displays a two-dimensional cross-section of the tissue being imaged.Other types of image can display blood flow,motion of tissue over time,the location of blood,the presence of specific molecules,the stiffness of tissue,or the anatomy of a three-dimensional region.
Compared to other prominent methods of medical imaging,ultrasonography has several advantages.It provides images in real-time (rather than after an acquisition or processing delay),it is portable and can be brought to a sick patient's bedside,it is substantially lower in cost,and it does not use harmful ionizing radiation.Drawbacks of ultrasonography include various limits on its field of view including difficulty imaging structures behind bone and air,and its relative dependence on a skilled operator.
