Abstract
The utility model provides a medical imaging probe which comprises a light source motivating component and a receiver. The light source motivating component is suitable for generating light signals and ultrasonic wave signals in a motivating mode, and the receiver receives the light signals and the ultrasonic wave echo signals. The light source motivating component comprises a pulse laser, a fiber optical fiber and a taper-shaped catoptric element. The taper-shaped catoptric element comprises a gradually-shrunk end facing towards a first outgoing end of the first optical fiber. The catoptric element is suitable for reflecting laser optical energy emitted by the first outgoing end and converting one part of the pulse optical energy into ultrasonic wave signals to enable the other part of the pulse optical energy and the ultrasonic wave signals of the other part to be illuminated on the inner wall of a tubular object to be measured in an annular mode. The ultrasonic wave signals are illuminated on the tubular object to be measured and generate the ultrasonic wave echo signals, and the pulse optical energy is illuminated on the tubular object to be measured and generates optical and audio signals. The medical imaging probe can measure optical and audio images and ultrasonic wave images of the tubular object to be measured in a sensing mode at the same time and can carry out fast imaging rapidly, and is simple in structure and low in cost.
Description
Technical field
This utility model relates to the medical image probe, relates in particular to the medical image probe of a kind of optoacoustic image and ultrasound video.
Background technology
The ultrasound imaging technique is used comparatively extensive in the little intrusive mood medical science of heart in the blood vessel at present, but the image contrast of speckle soft tissue, fibrous tissue and fatty tissue that traditional ultrasound video provides is not good, be not easy the analysis that component of organization is correct out, therefore also be necessary to capture the intravascular photoacoustic image.In known technology, when popping one's head in to capture the optoacoustic image with medical image, because seeing through optical fiber, pulsed light energy shines towards single direction, in order to obtain complete intravascular photoacoustic image, need to obtain complete image by the mode of mechanical scanning.The mode of so-called mechanical scanning is to rotate the optoacoustic image that medical image pops one's head in to obtain a plurality of fragments in blood vessel, then the image of these fragments is scrabbled up the optoacoustic image of the blood vessel of whole circle again.Complete optoacoustic image of acquisition need to rotate the medical image probe one circle like this, thus expend time in, and can't reach the function of instant imaging.
Summary of the invention
The purpose of this utility model is: a kind of medical image probe is provided, adopt the light source activation assembly can excite determinand to produce the optoacoustic signal, and produce the ultrasound signal by the light source activation assembly, can be whereby optoacoustic image and the ultrasound video in the sensing tubulose determinand and have advantages of fast imaging simultaneously.
The technical solution adopted in the utility model is: this utility model provides a kind of medical image probe, comprises light source activation assembly and receptor.The light source activation assembly is suitable for exciting and produces light signal and ultrasound signal, and receptor receives optoacoustic signal and ultrasound echo signal.
The light source activation assembly comprises pulsed laser, the first optical fiber, taper reflecting element.In addition, the taper reflecting element for example is little taper mirror, and its surface can be provided with the thin film that the partial pulse light energy can be converted to the ultrasound signal.In another embodiment, the taper reflecting element can directly be made by the material that the partial pulse light energy can be converted to the ultrasound signal.The taper reflecting element has the tapered end towards the first exit end of the first optical fiber.The taper reflecting element is suitable for reflecting the pulsed light energy that is penetrated by the first exit end, and convert the partial pulse light energy to the ultrasound signal, so that the pulsed light energy of another part and ultrasound signal annular are shone in the inwall of tubulose determinand, the ultrasound signal shines and produce the ultrasound echo signal behind the tubulose determinand, and pulsed light energy shines and produce the optoacoustic signal behind the tubulose determinand.Receptor has the acceptance division near the first exit end, to receive optoacoustic signal and ultrasound echo signal.
The material of described thin film can be gold, chromium or other suitable materials.
The beneficial effects of the utility model are: simultaneously the optoacoustic image in the sensing tubulose determinand and ultrasound video and can fast imaging, and the medical image sonde configuration that this utility model provides is simple, and cost is low.
