Ultrasonic measurement of height 174cm actual height should not differ much.
Equipment calibration: make sure that the ultrasonic measuring equipment used has been properly calibrated to ensure the accuracy of the results.
Correct posture: The subject should stand upright with feet together, shoulders relaxed, head not tilted, and eyes flat in front. This ensures that the spine is in an optimal position and helps to obtain accurate measurements. Measurement time: It is best to take the measurement in the morning after waking up, because after a night's rest, the body state is more relaxed and the measurement result is more accurate.
Environmental conditions: Avoid measuring in noisy environments that may interfere with ultrasonic signal reception. Ensure that the temperature of the measurement environment is appropriate, too cold or too hot may affect the measurement results. Multiple measurements: In order to improve the reliability of the measurement results, you can make multiple measurements and take the average value.
Recording data: Record the measurement results after each measurement for comparison and analysis. Professional operation: It is best to be operated by professional medical personnel or technicians to ensure the standardization of the measurement process and the accuracy of the measurement results.
Individual differences: Each person's bone structure and fat distribution are different, which may cause the ultrasound measurement results to deviate from the actual height. Measurements should be taken in conjunction with the individual's actual condition.
