Non-destructive supersonic induced-luminessing imaging method and equipment

Abstract

The imaging method includes applying weak supersonic wave directly onto organism or tissue to induce endogenous luminescence; receiving the light by an optical receptor and converting the light into electrical signal; A / D converting the electrical signal into digital signal; and digital signal treatment to obtain the structure image of the organism or tissue. The imaging equipment consists of a supersonic wave generator assembly, an optical receptor assembly, an A / D converter and a computer. Combining the strong permeability of supersonic wave in organism and the high resolution and no damage of optical imaging, the present invention can obtain high-resolution image for biomedical imaging diagnosis.

Description

technical field [0001] The present invention relates to a medical imaging diagnosis technology, in particular to an ultrasound-induced ultrasound-induced luminescence that uses harmless weak ultrasound to induce organisms or tissues to produce their own internal luminescence, and uses the endogenous luminescence to perform non-damaging structural imaging. Luminescent non-destructive imaging method and device thereof. Background technique [0002] Among the imaging technologies commonly used in medical imaging diagnosis at present, X-ray transmission imaging, X-ray tomography (CT), and nuclear magnetic resonance imaging all have a large degree of damage to human tissues, and X-ray tomography, nuclear magnetic resonance imaging, etc. The cost of the resonance imager is relatively expensive; the B-type ultrasonic imaging has basically no damage to the human body, and the cost of the B-type ultrasonic imager is also low, but because it is tissue interfa...

Problems solved by technology

[0002] Among the imaging technologies commonly used in medical imaging diagnosis at present, X-ray transmission imaging, X-ray tomography (CT), and nuclear magnetic resonance imaging all have a large degree of damage to human tissues, and X-ray tomography, nuclear magnetic resonance imaging, etc. The cost of the resonance imager is relatively expensive; the B-type ultrasonic imaging has basically no damage to the human body, and the cost of the B-type ultrasonic imager is also low, but because it is tissue interface reflection imaging, it cannot achieve tomography, and the resolution is low ( For in vivo tissues with simple structures, the best resolution is a few millimeters), and the contrast is poor

Optical imaging technology (including time-resolved optical imaging, frequency-domain optical imaging, optical coherence tomography, etc.) has the characteristics of no damage to the human body and high resolution. With strong scattering and absorption, the current technical level can only achieve imaging of shallow biological tissues with a depth of millimeters, and it is difficult to achieve accurate measurement of deep tissues. At the same time, these methods of imaging are realized by using the optical properties of tissues However, its imaging contrast is solely derived from the difference in the optical properties of the tissue
