Abstract

The invention provides a novel high-rate rotary optical-acoustic combined imaging probe and a conduit. The probe comprises a photoconduction optical fiber, a GRIN lens, a sound generation signal lead, an electroacoustic transducer, a micromotor driving lead, a micromotor and a reflector. A detection acoustic beam produced by the electroacoustic transducer in the probe and a detection light beam produced by the optical fiber and the GRIN lens are spread to a far-end along an axial direction, then are reflected by the reflector, then are spread along a radial direction and irradiate a sample to be detected. The micromotor is used for rotating the reflector thereby changing directions of the detection acoustic beam and light beam. Through combination with probe axial motion, optical-acoustic spiral scanning imaging is realized. The imaging conduit is prepared from the probe as a core and the probe can move in an outer sheath and can be protected. The novel rotary type optical-acoustic combined imaging probe improves an optical-acoustic combined imaging rate and improves image quality.

Description

technical field [0001] The invention relates to the technical field of optical and acoustic imaging, in particular to a rotary combined optical and acoustic imaging probe and catheter. Background technique [0002] Optical imaging technology has a long history, but in recent years, due to the development of laser technology, rotary scanning optical imaging has been greatly developed. , to obtain the two-dimensional image of the surface of the object or the three-dimensional image of the object by means of helical scanning. This technique is particularly suitable for imaging tubular structures, and its representative techniques include laser scanning microscopy, low-coherence imaging, infrared spectroscopy and fluorescence imaging. Because of the short wavelength of light, these techniques can achieve very high resolution (~10 microns), among which low-coherence imaging has certain penetration and can perform subcutaneous detection, while infrared spectroscopy and fluoresc...
