AUTO ADJUSTMENT OF AUDIO VOLUME IN ULTRASOUND SYSTEMS

FIELD OF INVENTION

The invention generally relates to ultrasound systems, and more particularly to automatic volume adjustment based on environmental noise, user preferred settings, and venous speed.

BACKGROUND OF THE INVENTION

Compact ultrasound devices are increasingly used in more and more complex environments. For example, the ultrasound devices are used in Ultrasonography Department in hospitals, in ambulances, at an accident scene, a playground, around pet animals, and so on. Different environments have different noise levels, and the default audio volume of the ultrasound devices may be too low or too loud for a user to make observations comfortably and accurately.

Further, if the audio volume is too loud, it may frighten the patient and user. If the audio volume is too low, it may lead to inaccurate observations or readings. Furthermore, the audio volume is also depends on blood speed in the veins, or venous speed. For low venous speed, the audio volume may be too low for hearing comfortably, while for high venous speeds, the audio volume may be too loud for the user. The user may frequently need to change the audio volume according to noise level of using environment, wasting significant time and energy.

Hence there exists a need for automated audio volume adjustment for ultrasound devices, such as those using pulse wave (PW) Doppler ultrasound, continuous wave Doppler (CWD) ultrasound, and telemed video data (TVD) ultrasound. [INVENTORS – PLEASE CONFIRM THE ACRONYMS PW, CWD and TVD]  

BRIEF DESCRIPTION OF THE INVENTION

The invention provides an automated audio volume adjustment based on the environmental noise levels and venous speed to match an audio volume defined as suitable by a user for one or more ultrasound modes.

DETAILED DESCRIPTION OF THE INVENTION

Techniques described herein automatically adjust the audio volume for PW, CWD and TVD mode to a level that a user can hear comfortably, using environmental noise measurements and different venous speeds. The techniques work by first capturing user preference of a comfortable audio volume levels for each mode of operation, and then adjusting the audio volume according to the environmental noise and venous speeds. For example, if the venous speed is high, the volume will automatically be high and in quiet environments, the techniques described herein automatically lower the volume levels to match the user preference for a comfortable volume level. If the venous speed is low, the volume will automatically be low, and in noisy environments, the techniques described herein automatically raise the volume levels to match the user preference for a comfortable volume level.

Specifically, the user sets comfortable Audio Volume (%) for PW, CWD and TVD mode. The system obtains and records the noise level (dB) of the environment by using sound sensors, and further measure the current maximum venous speed.

The system then captures the m...
