Method for measuring surface temperature of probe of ultrasonic diagnostic device

Abstract

The invention discloses a method for measuring the surface temperature of a probe of an ultrasonic diagnostic device, which relates to the technical field of medical ultrasonic diagnostic devices. Thedevice uses the measured values of a single temperature sensor, and the technology based on the cross-correlation signal processing algorithm is utilized for carrying out accurate estimation on the environmental temperature, thereby calculating the surface temperature of the probe. Compared with the prior technology for measuring the surface temperature of the probe, the method can utilize the historical temperature records of the temperature sensor for carrying out analysis, thereby obtaining the estimated value of the environmental temperature; and the estimated value is obtained by carrying out the calculation and the analysis on the current on-site measurement data of a patient, so that the precision is much higher than that of the practice of assuming the environmental temperature inadvance. In addition, the method only needs to use one temperature sensor, thereby greatly reducing the assembly difficulty of the probe, the complexity of an internal circuit and the whole cost of asystem.

Description

technical field [0001] The invention relates to the field of medical ultrasonic diagnostic equipment, in particular to a method for measuring the surface temperature of a probe of the ultrasonic diagnostic equipment. Background technique [0002] Ultrasonic echo imaging technology has been widely used in military, medical and other fields. By transmitting ultrasonic waves to the target area, the receiving device receives the reflected echo signals, and suppresses the echo signals through signal processing technology and image processing technology. The useless parts in the final form the image of the target area. [0003] In the medical field, which is closely related to each of us's daily life, ultrasonic echo imaging technology has achieved considerable development. At present, various medical ultrasonic diagnostic equipment such as B-ultrasound have been widely used in clinical diagnosis in various hospitals. In addition to the traditional The black-and-white ultrasound ...

Problems solved by technology

This method can accurately measure the surface temperature of the probe, but because two temperature sensors and auxiliary electronic devices and wires are placed in the narrow space inside the probe, the difficulty of probe assembly is greatly increased; in addition, each temperature sensor requires follow-up The processing part has a separate A / D converter, which also increases the cost of the system; finally, although the second temperature sensor can measure the ambient temperature, because it shares a small probe space with the first temperature sensor Therefore, it will be more or less affected by the heat generated by the probe, and the ambient temperature obtained is only an approximation.
