Abstract

The invention provides an ultrasonic temperature measuring device and method based on back scattering energy. The device comprises: an ultrasonic probe used for emitting an ultrasonic emission signaland receiving an ultrasonic reflection signal at the same time; a signal processor which is used for receiving the ultrasonic reflection signal acquired by the ultrasonic probe and sending the ultrasonic emission signal to the ultrasonic probe; and a central processing unit which is used for carrying out image output processing on the signals input by the signal processor and calculating the bodytemperature of the examined person, wherein the signal characteristic extracted by the central processing unit is the amplitude of a radio frequency return signal, calculating the change of back scattering energy, and determining the corresponding temperature change. The ultrasonic temperature measuring device and method have the advantages of no ionizing radiation, high temporal and spatial resolution, tissue penetrability, low measurement cost, wide availability and the like. The situation that the body temperature is affected by the environment, and the infrared temperature measuring gun cannot obtain the real body temperature value of the examined person is avoided.

Description

technical field [0001] The disclosure belongs to the technical field of electronic equipment, and in particular relates to an ultrasonic temperature measurement device and method based on backscattered energy. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] At present, the main temperature measuring guns on the market are based on infrared forehead temperature measurement; and this kind of infrared temperature measuring gun is often affected by the external environment, resulting in a temperature measurement result that is far from the real body temperature of the human body. For example, in an air-conditioned room, through The human body temperature obtained by the infrared temperature measuring gun is often affected by the room temperature, and the temperature measurement result cannot reflect the real body temperature of the human bod...
