Problems solved by technology

However, in this system procedure, the IVC is easily lost during respiration, the video clip is forced to pause, and manual re-initialization is performed to finally complete the entire process, causing trouble for the clinician
[0006]While these systems reduce repetitive tasks for physicians, they either require careful selection of reference points during initialization, multiple manual entries, or multiple interactions To complete the measurement, its reliability is reduced, prone to human error

Embodiment Construction

[0080] The following examples of the present invention are described in detail below. The following examples are implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following the embodiment.

[0081] The invention was tested on ultrasound data collected from pigs. Two clinicians (both with >6 years experience in ultrasound clinical practice) performed the scans using an ultrasound instrument CX-50 (Philips Healthcare, Bothell, US) equipped with a curved probe (C5-1, central frequency: 1-5 MHz). Three ultrasound video data were collected from animals by each clinician. Algorithms developed in the laboratory were applied to collected ultrasound data using Matlab (MathWorks, Natick, MA, USA) for the development of an automated IVC movement tracking and measurement system.

Abstract

The invention provides an inferior vena cave ultrasonic dynamic automatic measurement system and method. The system comprises an automatic accurate IVC measurement point positioning module, an automatic IVC diameter measuring module, an automatic image rotation module, an IVC motion tracking module and an IVC diameter change calculation module. The system can greatly reduce manual input of a doctor in ultrasonic IVC measurement, biomarkers do not need to be carefully selected, the interactive frequency is reduced, and the consistency of operators is greatly improved, so that data is accurate,and the dependency on the operators is small.

Description

technical field [0001] The invention belongs to the technical field of ultrasound, in particular to a system and method for ultrasonic dynamic automatic measurement of inferior vena cava. Background technique [0002] Ultrasonography has been increasingly used by clinicians to measure the inferior vena cava (IVC) due to efficiency and cost advantages. Ultrasonic measurement can be used to quickly and conveniently measure the IVC diameter change during the patient's breathing, and provide various physical condition information of the patient in time. [0003] However, ultrasound IVC measurements may be affected by IVC movement with respiration. First, measuring IVC in constant motion is time-consuming and laborious. To measure IVC, the clinician must hold the ultrasound probe with one hand while taking the IVC measurement on the ultrasound device with the other hand, or take the measurement off-line. Therefore, ultrasound IVC measurement relies on the experience and skill ...
