Abstract

The focussing ultrasonic modulation reflection type optical chromatographic imaging method utilizes the focussing ultrasonic technique to make modulation and tissue location of the laser injected into deep biological tissue, and uses optical technique to make high-sensitivity detection and real-time high-speed. Fourier transform to process signal, and can obtain the chromatogram of pathologic changed tissue region. The injection laser mand modulation ultrasonic wave are coaxially-retained, and its signal exciting device and receiving device adopt homoside reflection mode. Said optical chromatographic imaging equipment is formed from laser, optical polarization component, ultrasonic component, photo-electric conversion component, signal display and real-time rapid Fourier transform module and computer.

Description

technical field

[0001] The invention relates to biomedical imaging technology, more precisely, a focused ultrasound modulation reflective optical tomography method.

[0002] The invention also relates to a device for implementing the above optical tomography method. Background technique

[0003] At present, widely used biomedical imaging diagnostic technologies, such as X-ray tomography (CT) and nuclear magnetic resonance imaging, etc., have certain damage to human tissues, and X-ray tomography devices and nuclear magnetic resonance equipment are expensive; although B-mode ultrasonic detection There is basically no harm to people, and the cost of the instrument is relatively low. However, due to the reflection imaging of the tissue interface, tomography cannot be realized, and the resolution is also low. For tissues in the body with simple structures, the best resolution is a few millimeters. And the resolution drops further when examining the moving organs. Although new t...
