Aortic artery measuring probe, device and method of measuring diameter of aortic artery

An aortic artery measuring device adapted for measuring a diameter of an aortic artery of a subject to be measured, the aortic artery measuring device comprising:

• an aortic artery measuring probe, comprising:
• a flexible substrate;
• a sensor array disposed on the flexible substrate, the sensor array comprising an array of ultra-wideband sensors and the array being a M×N array, wherein M is an integer greater than or equal to 1, and N is an integer greater than or equal to 2, the array of ultra-wideband sensors are positioned on the subject, and the flexible substrate is deformed into an arc and focused on the aortic artery of the subject;
• and
• a signal processing module electrically connected with the aortic artery measuring probe,
• the array of ultra-wideband sensors transmitting a radio wave into the subject, the radio wave reflected by a tissue interface of an artery wall of the aortic artery of the subject, the array of ultra-wideband sensors receiving a reflected signal formed by the reflection of the radio wave, and the reflected signal analyzed by the signal processing module to define a diameter of the aortic artery.

A method of measuring a diameter of an aortic artery, comprising:

• providing an aortic artery measuring device comprising an aortic artery measuring probe and a signal processing module electrically connected with each other, the aortic artery measuring probe comprising a flexible substrate and a sensor array disposed on the flexible substrate, the sensory array having an array of ultra-wideband sensors and the array being a M×N array, wherein M is an integer greater than or equal to 1, and N is an integer greater than or equal to 2, the array of ultra-wideband sensors are positioned on a subject, and the flexible substrate is deformed into an arc and focused on the aortic artery of the subject;
• positioning the aortic artery measuring probe of the aortic artery measuring device at a first position of the subject for a first predetermined time interval;
• within the first predetermined time interval, the ultra-wideband sensors transmitting a radio wave into the subject, the radio wave reflected by a tissue interface of an artery wall of the aortic artery of the subject, and the ultra-wideband sensors receiving a reflected signal formed by the reflection of the radio wave;
• and
• the signal processing module analyzing the reflected signal to define a diameter of the aortic artery.
