US 2026/0043909 A1 · ULTRASONIC DIAGNOSTIC IMAGING SYSTEM WITH TGC CONTROL

Abstract

A TGC control system for an ultrasonic diagnostic imaging system has TGC controls which are constructed as a single elongated module with periodic enlarged regions spaced along the elongated module. The number of enlarged regions is equal to the number of TGC zones to be controlled. Touch sensors are located on opposite sides of each enlarged region and a user can touch one side of an enlarged region to increase the gain in a TGC zone, and touch the other side of the enlarged region to decrease the TGC gain in the zone. The amount of gain adjustment is determined by the height at which the user touches the enlarged region.

Dependent claims

An ultrasonic diagnostic imaging system for producing ultrasound images adjusted for depth-dependent ultrasound attenuation by TGC (time gain compensation) control comprising:

TGC amplifiers located in a receive echo signal path of the imaging system;
a source of a TGC gain characteristic;
and
a TGC control module adapted to enable adjustment of the TGC gain characteristic, the TGC control module comprising a plurality of enlarged regions, each for adjusting a segment of a TGC gain characteristic and each further comprising a plurality of touch sensors located on opposite sides of an enlarged region;
and
a TGC gain processor, responsive to the touch sensors and to the TGC gain characteristic, adapted to apply adjusted TGC gain to the TGC amplifiers.
