The invention relates to an ultrasonic imaging equipment time gain compensation adjusting device and an ultrasonic imaging equipment time gain compensation adjusting method. The ultrasonic imaging equipment time gain compensation adjusting device comprises N time gain compensation signal control input components and at least one function key; the N time gain compensation signal control input components and the at least one function key are respectively associated with M segments of time gain compensation position information of ultrasonic imaging equipment through the combination of mutual status information; and the M segments of time gain compensation position information of the ultrasonic imaging equipment are adjusted through actions of the time gain compensation signal control input components and the at least one function key, wherein M is a natural number more than 1, N is a natural number more than or equal to 1, and M is more than N. Through a design of combining the TGC signal control input devices and the function key, N TGC signal control input devices are only used to realize the TGC adjusting function same as that of M TGC signal control input devices (M is more thanN), so that the area of a panel is reduced, the panel is more compact, the volume of the whole machine can be further reduced, and the cost of the whole machine also can be controlled.
