Problems solved by technology

On the one hand, the saline contrast method has high accuracy, and on the other hand, the pulmonary vascular pulsation method has the advantage of real-time monitoring. The two methods have the characteristics of complementary advantages and disadvantages, but there is no relevant basic research on the combination of the two methods at home and abroad. to report

Abstract

The invention relates to a pulsatile perfusion image reconstruction method, system and device corrected by brine radiography. The method comprises the following steps: acquiring a band-pass filtering electrical impedance curve of a patient to generate a pulsation graph; and generating a pulsatile perfusion image corrected by brine contrast based on the correction factor and the pulsatile graph. The pulsatile perfusion image corrected by brine contrast not only contains pulsatile impedance data of a lung perfusion area, but also contains forward blood flow impedance data, so that real-time and accurate generation of the lung perfusion image is realized.

Description

technical field [0001] The present invention relates to the field of intelligent medical technology, and more particularly, to a method, system, device and computer-readable storage medium for reconstructing a pulsatile perfusion image corrected by saline angiography. Background technique [0002] As a non-invasive, continuous, dynamic, non-radiation advanced lung ventilation monitoring technology at the bedside, EIT mainly applies a weak current through local electrodes to sense the changes in the bioelectrical impedance of the thoracic cavity during the ventilation process, and then uses the corresponding imaging algorithm to monitor the lung ventilation function. state. EIT pulmonary perfusion imaging can generally be divided into two methods: heart-related periodic pulmonary vascular beat and high-conductivity agent-enhanced contrast. The periodic pulmonary vascular pulsation method mainly reflects the regional pulmonary perfusion by analyzing the regional periodic pulm...
