[ detailed description ] embodiments

The technical solutions of the embodiments of the present invention are explained and illustrated below with reference to the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, and not all embodiments. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative effort belong to the protection scope of the present invention.

Reference in the specification to "one embodiment" or "an example" means that a particular feature, structure or characteristic described in connection with the embodiment itself may be included in at least one embodiment of the patent disclosure. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

The first embodiment is as follows:

as shown in fig. 1, the present embodiment provides an ultrasonic photoacoustic breast cancer detector, which is used for detecting breast cancer, the whole shape of which is similar to that of a female bra, and a patient needs to wear the breast cancer detector on his body during detection, and the ultrasonic photoacoustic breast cancer detector comprises a cup portion 1, an ultrasonic detection module for collecting ultrasonic signals, and a photoacoustic detection module for collecting photoacoustic signals, wherein the cup portion 1 is used for providing necessary space required by the worn breast, and also provides space for the ultrasonic detection module and the photoacoustic detection module.

Internal structure of cup portion 1 as shown in fig. 2, the photoacoustic detection module includes a phased LED array including a plurality of LED light sources 3, and the plurality of LED light sources 3 are distributed on the inner side wall of cup portion 1. A plurality of LED light sources 3 included in the phased LED array irradiate the organ to be detected from different directions according to a set program, and then the ultrasonic probe 2 receives sound waves emitted by the fact that the tissues of the organ to be detected absorb heat of the LED light sources 3.

The ultrasonic detection module comprises ultrasonic probes 2, the ultrasonic probes 2 are also distributed on the inner side wall of the cup part 1, and the ultrasonic probes 2 and the LED light sources 3 are alternately and uniformly distributed. In this embodiment, the ultrasonic detection module further comprises a couplant bag 5 and a couplant conduit 4 which are located outside the cup portion 1, and the couplant in the couplant bag 5 enters the cup portion 1 through the couplant conduit 4.

As shown in fig. 3, the ultrasonic probe 2 includes an acoustic lens layer 21, a matching layer 22, a piezoelectric sensor array layer 23, and a backing material layer 24. The acoustic lens layer 21 is an end directly contacting the organ to be detected to focus in the lateral and/or longitudinal directions. The matching layer 22 serves to reduce multiple reflections due to the difference in acoustic impedance between the skin and the acoustic lens layer 21. The piezoelectric sensor array element layer 23 includes a piezoelectric material, which may be a piezoelectric crystal or a composite piezoelectric material, and the geometric shape and size thereof may be designed according to the diagnostic scenario and requirements, including various shape designs such as a convex array, a linear array, etc., which are not limited herein. The piezoelectric sensor array element layer 23 is used for transmitting/receiving ultrasonic waves to complete the sound electricity and electricity-electricity conversion work, and can convert an electric signal into an ultrasonic signal and convert the ultrasonic signal into an electric signal, namely, the piezoelectric sensor array element layer has double functions of ultrasonic transmission and ultrasonic receiving. Under the power-on state, the piezoelectric material can generate elastic deformation, so that ultrasonic waves are generated; in the opposite case, when the ultrasonic wave passes through the piezoelectric material, it can generate elastic deformation, and then the voltage is changed. The backing material layer 24 serves to dampen vibrations from the piezoelectric material, shorten the wavelength and improve axial resolution. The ultrasonic detection module generates a desired image by controlling an ultrasonic signal transmitted therefrom or using a received ultrasonic signal, and allows the image to be displayed in real time, without radiation exposure, with high safety. The ultrasound probe 2 further comprises a support frame 25. The support frame 25 is used for mounting the ultrasonic probe 2 on the inner side wall of the cup portion 1, and the sequence of the layers of the ultrasonic probe 2 from the detected organ to the inner side wall of the cup portion 1 is as follows: the acoustic lens layer 21, the matching layer 22, the piezoelectric sensor array layer 23, and the backing material layer 24, in the present embodiment, the backing material layer 24 of the ultrasonic probe 2 is mounted on the support frame 25, that is, the piezoelectric sensor array layer 23 is located between the matching layer 22 and the backing material layer 24. The acoustic lens layer 21, matching layer 22, and piezoelectric sensor array layer 23 are mounted on a support frame 25 by a backing material layer 24.

When the ultrasonic photoacoustic breast cancer detector is used, a patient wears the ultrasonic photoacoustic breast cancer detector provided by the embodiment, as shown in fig. 4:

in the aspect of the ultrasonic detection module, because the ultrasonic detection needs the assistance of the couplant, the couplant in the couplant bag 5 enters the cup parts 1 through the couplant guide pipe 4, and because the ultrasonic photoacoustic breast cancer detector is worn, the couplant entering the cup parts 1 can be extruded naturally in a narrow space and smeared on the surface of the detected organ. The couplant in the couplant bag 5 can enter the cup parts 1 in a manual extrusion mode, a conveying device can be additionally arranged on the couplant bag 5, the couplant can be automatically injected according to the set demand of the couplant, and the couplant in the cup parts 1 can be recovered to the couplant bag 5 through the conveying device after use. The transfer of fluids, such as coupling agents, is not limited herein, as is known in the art. When ultrasonic detection is carried out, ultrasonic wave transmitting sequences of the ultrasonic probes 2 and ultrasonic wave receiving sequences of the ultrasonic probes 2 are preset, the ultrasonic probes 2 which transmit ultrasonic waves according to the preset, the ultrasonic probes 2 which receive the ultrasonic waves receive transmitted ultrasonic waves and/or reflected ultrasonic waves, tomography is carried out on the mammary gland, the mammary gland is detected in an all-around mode, accurate three-dimensional images are formed, and judgment of a doctor on the position of the mammary gland tumor is improved. The sequence of the ultrasonic probes 2 for transmitting ultrasonic waves and the sequence of the ultrasonic probes 2 for receiving ultrasonic waves can be flexibly set by a doctor according to actual clinical needs, and are not limited herein. Compared with the existing ultrasonic examination, the ultrasonic examination is generally in a supine posture, the handheld ultrasonic probe is clung to the breast skin for detection, the ultrasonic image mainly takes two-dimensional imaging, and the breast tissue is soft, so that the breast can deform along with the extrusion of the probe, and the conventional ultrasonic examination method cannot accurately image.

In the aspect of the photoacoustic detection module, the coupling agent is also needed to be assisted, and the coupling agent is the same as the coupling agent in the aspect of the ultrasonic detection module, and the details are not repeated here. When the photoacoustic detection is carried out, the irradiation sequence of the LED light sources 3 included in the phased LED array is preset, the LED light sources 3 included in the phased LED array irradiate the detected organ from different directions according to the preset sequence, and when the tissue of the detected organ is irradiated by light beams, the energy of the light is absorbed by the tissue to generate thermoelastic expansion, and then sound waves are generated. Because tumor cells stimulate the generation of new blood vessels during growth, the distribution of local aerobic and anoxic hemoglobin of the tumor is changed, and therefore, when the tumor cells are irradiated by near infrared light, different absorption rates which are obviously different from surrounding tissues can be generated, and further, different sound wave emission is generated. The ultrasonic probe 2 receives the sound wave generated by the tissue of the organ to be detected absorbing the heat of the LED light source 3. Three-dimensional acoustic data of the detected organ can be obtained by irradiating the tissue of the detected organ from different directions, and then image reconstruction is carried out to form an accurate three-dimensional functional image. Different from a single laser light source of the photoacoustic system in the prior art, the present embodiment adopts a cheaper LED as a light source, so that the whole cost of the ultrasonic photoacoustic breast cancer detector is low, and the safety is higher.

When the ultrasonic photoacoustic breast cancer detector provided by the embodiment is used, the two modalities can be used for imaging simultaneously or respectively, and the two modalities are not limited herein.

The ultrasonic photoacoustic breast cancer detector provided by the embodiment fuses an ultrasonic mode and a photoacoustic mode, carries out autonomous tomography in a standing state of a patient to form an accurate three-dimensional image, provides the three-dimensional image of an ultrasonic morphological structure, and simultaneously forms a photoacoustic image by the aid of a phased LED array, so that information from various imaging sources can be comprehensively expressed on one image, the diagnosis accuracy is improved, a doctor can know the comprehensive condition of a pathological change tissue or organ conveniently, more accurate diagnosis is made or a more scientifically optimized treatment scheme is made, meanwhile, the patient does not need to roll over multiple places to detect, the burden of the patient is reduced, and the diagnosis efficiency is improved.
