Biological tissue magnetic-acoustic conductivity detection device

Abstract

The invention discloses a biological tissue magnetic-acoustic conductivity detection device. The biological tissue magnetic-acoustic conductivity detection device comprises a conductivity detection water tank platform and a controlling and signal-processing circuit, wherein the conductivity detection water tank platform comprises a detection water tank, a static magnetic field generation device, a water immersion type probe, a probe movement control device and a signal detection device. The magnetic-acoustic conductivity detection device provided by the invention is capable of early discovering the abnormality of physiological pathology by detecting change of electrical properties of the biological tissue and supplying data support for early diagnosis of diseases; meanwhile, excitation coils are not used; the influence of an alternating magnetic field on the current in a sample and the interference of the alternating magnetic field on detection devices such as ultrasonic transducers and the like are avoided; the problem that step signals in induction type magnetic-acoustic imaging are difficult to implement is avoided; the interference and the distortion caused by electrode noise and contact noise signals in direct detection of the electrode in voltage injection type magnetic-acoustic imaging are reduced; and the defect of low spatial resolution caused by dispersive distribution of injection current is avoided.

Description

technical field [0001] The invention relates to the technical field of cancer detection, in particular to a detection device for magnetoacoustic conductivity of biological tissue. Background technique [0002] With the acceleration of the pace of society, the increase of people's pressure, and the aggravation of air and environmental pollution, more and more cancer patients have been discovered. A device that can diagnose cancer at an early stage or in the early stages of cancer formation will benefit all mankind. [0003] In the current imaging system, the image formed by X-CT has the characteristics of high resolution and good contrast, but because X-ray has ionizing radiation, it has certain damage to the human body, so its application range is limited; Fast, high resolution, no harm to the human body, etc., but its contrast is poor, so the clarity of the image is limited. In addition, ultrasound imaging is the same as X-CT. The images are all morphological and anatomic...

AI Technical Summary

Problems solved by technology

[0003] In the current imaging system, the image formed by X-CT has the characteristics of high resolution and good contrast, but because X-ray has ionizing radiation, it has certain damage to the human body, so its application range is limited; Fast, high resolution, no harm to the human body, etc., but its contrast is poor, so the clarity of the image is limited

In addition, ultrasound imaging is the same as X-CT. The images are all morphological and anatomical imaging, and no functional imaging is performed on human tissue. Early diagnosis

Although magnetic resonance has the advantages of high resolution and easy acquisition of three-dimensional images, the traditional magnetic resonance technology that has been widely used cannot perform functional imaging of human tissues and organs, and magnetic resonance imaging is expensive, and the use and maintenance costs are extremely high , so it is difficult to popularize among ordinary people

Early cancer patients cannot be diagnosed by ultrasound, X-CT, magnetic resonance and other methods, and can only be diagnosed by ultrasound, biopsy and other methods when the cancer reaches a certain level. Mechanism of method and assessment, so as to remind cancer patients in time for early treatment, so as to avoid missing the best treatment time
