Description

technical field

[0001] The invention belongs to medical equipment or instruments, and relates to an electrical impedance tomography method and a device thereof which can be used for bedside image monitoring. Background technique

[0002] Some diseases with high morbidity in clinical diagnosis and treatment now require imaging technology that can be used for bedside monitoring: stroke, subacute traumatic brain injury, chronic intracranial hemorrhage, postoperative brain complications, neonatal intracranial hemorrhage, Delayed internal hemorrhage or local ischemia of abdominal organs, organ transplantation, etc. all require bedside image monitoring technology.

[0003] However, none of the existing imaging technologies can be used for bedside image monitoring: such as the existing CT, MRI, PET, ultrasound, etc., which not only require huge equipment and high costs, are complicated to operate, have certain damage to the human body, and are impossible Do bedside dynamic, real-t...
