Abstract
Systems and methods for adjusting gain are described. The systems includes a probe. The probe includes a housing, a transducer element configured to receive a signal, and an adjustable gain amplifier located inside the housing and configured to adjust a gain provided to the signal based on a function having a slope other than zero.
Claims21
An ultrasound probe comprising:
- a housing;
- a transducer element configured to receive a signal;
- and
- an adjustable gain amplifier located inside said housing and configured to adjust a gain provided to the signal based on a function having a slope other than zero.

An ultrasound imaging system comprising:
- an ultrasound probe having a housing;
- a transducer element located within said housing and configured to receive a reflected echo signal from a subject;
- an amplifier located within said housing and configured to communicate with said transducer element, said amplifier configured to receive an input signal from said transducer element and output an amplified signal based on the input signal;
- an adjustable feedback loop connected with said amplifier and configured to provide a feedback signal to said amplifier, wherein the feedback signal varies based on the amplified signal.
1 more element
A method for adjusting a gain of an amplifier, said method comprising:
- receiving a signal from a subject;
- amplifying the signal according to a gain;
- and
- adjusting the gain during a period of time in which the signal is received from a near-field, the near-field defining an area within the subject.
