Medical image full-wave-field imaging device and method

Abstract

The invention relates to the field of medical imaging, in particular to a medical image full-wave-field imaging device and method. The medical image full-wave-field imaging device comprises a collection platform, electric connectors, high-frequency ultrasonic transducers, a flexible film and a medium liquid, wherein a wearing opening is formed at one end of the basin-shaped collection platform, a spherical coating surface is formed to enclose the wearing opening, and a person to be detected wears the collection platform through the wearing opening; the electric connectors are distributed on the coating surface in a spherical array manner; each electric connector is electrically connected with one high-frequency ultrasonic transducer, and the high-frequency ultrasonic transducers are electrically connected with a pulse controller; the basin-shaped flexible film is positioned in the wearing opening, is tightly attached to the inner wall of the coating surface, is located on the inner side of the wearing opening to form a collection area for signal collection; and the flexible film is filled with the medium liquid. The liquid-state contact medium is designed, the energy of ultrasonic waves penetrating through a human body is increased, the wave impedance between the body surface and the outside is reduced, a stable observation system is formed, and the aim of high-precision imaging is achieved.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to a medical imaging full-wave field imaging device and method. Background technique [0002] Medical imaging refers to the technology and processing process of obtaining internal tissue images of the human body or a certain part of the human body in a non-invasive manner for medical treatment or medical research. It includes the following two relatively independent research directions: medical imaging system and medical image processing. The former refers to the process of image formation, including the research on imaging mechanism, imaging equipment, imaging system analysis and other issues; the latter refers to the further processing of the obtained image, the purpose of which is to make the original image that is not clear enough Restoration, or to highlight certain feature information in the image, or to classify the image as a pattern, etc. [0003] As a science, medical imag...

Problems solved by technology

[0004] However, in the field of modern medical imaging, medical imaging technologies mainly include nuclear magnetic resonance (MRI), CT, ultrasound and other means. Among them, nuclear magnetic resonance has high cost and bulky equipment (ten million counterfeit, hundreds of tons of steel shielding strong magnetic field, magnetic field iron core It can also cost dozens of tons or even hundreds of tons), and has special requirements for detection targets (such as no metal); although CT has high precision, it has a large radiation dose, large equipment volume, and relatively high cost; ultrasonic is small in size and low in cost. However, it only uses simple reflected wave imaging, which has shortcomings such as insufficient precision, inability to penetrate special parts, and inaccurate imaging of cluttered wave fields in special parts (such as skulls, bones, etc.). Oscillating back and forth in the bone cavity, it is difficult to identify reflections and multiple clutter interference, and cannot be accurately imaged
