Description

Optical ultrasonic breast cancer detector and medical equipment

[ technical field ] A method for producing a semiconductor device

The invention relates to the technical field of medical equipment, in particular to an optical ultrasonic breast cancer detector and medical equipment.

[ background of the invention ]

The dynamic scattering optical imaging (dynamic differential optical tomography) system is very beneficial to early diagnosis of the breast cancer, and has the advantages of low price, safety, high accuracy, no radiation and low risk compared with molybdenum target X-ray, CT, MRI and other imaging diagnosis methods. However, the existing dynamic scattering optical imaging system can only provide optical absorption information of whether tissues in the breast are cancerated, and cannot further provide position and size information of the tumor.

Ultrasonic detection is used in many applications such as medical diagnosis, treatment, and ultrasonic inspection. As an example of the medical apparatus, an ultrasound imaging apparatus emits an ultrasound signal from a surface of a subject body toward a target site of the subject, and acquires a tomographic image of soft tissue or an image of blood flow using information of the reflected (or transmitted) ultrasound signal (ultrasound echo signal) without being invasive. Compared to other image diagnostic apparatuses such as an X-ray diagnostic apparatus, an X-ray Computed Tomography (CT), a Magnetic Resonance (MRI) apparatus, and a nuclear medicine diagnostic apparatus, an ultrasonic imaging system is small in size, low in price, allows images to be displayed in real time, has no radiation exposure, has high safety, and is widely used for diagnosis of heart or abdominal regions, urinary systems, and obstetric/gynecological diseases.

In clinical diagnosis, images of a single modality often cannot provide enough information required by a doctor, so that the accuracy of diagnosis is affected, while images of different modalities require that a patient rotates multiple places to perform detection respectively, and then the doctor performs diagnosis according to a detection result, so that the diagnosis efficiency is low.

The first embodiment is as follows:

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

As shown in fig. 2, the ultrasonic piezoelectric detection module includes ultrasonic probes 6, and the ultrasonic probes 6 are distributed on the inner side wall of the cup portion 1 which is not covered by the pressurized air bag 4 and are circumferentially and uniformly distributed on the inner side wall which is not covered. In other words, after the patient wears the optical ultrasound breast cancer detector, the plurality of ultrasound probes 6 ultrasonically detect the vicinity of the breast around the root thereof. Furthermore, in the present embodiment, the ultrasonic piezoelectric detection module further includes a couplant bag 7 and a couplant conduit 8, which are located outside the cup portion 1, and the couplant in the couplant bag 7 enters the cup portion 1 through the couplant conduit 8.

As shown in fig. 4, the ultrasonic probe 6 includes an acoustic lens layer 61, a matching layer 62, a piezoelectric sensor array layer 63, and a backing material layer 64. The acoustic lens layer 61 is an end directly contacting the organ to be detected for focusing in the lateral and/or longitudinal directions. The matching layer 62 serves to reduce multiple reflections due to the difference in acoustic impedance between the skin and the acoustic lens layer 61. The piezoelectric sensor array element layer 63 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.

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 64 serves to dampen vibrations from the piezoelectric material, shorten the wavelength and improve axial resolution. The ultrasonic piezoelectric detection module generates required images by controlling ultrasonic signals transmitted by the ultrasonic piezoelectric detection module or utilizing received ultrasonic signals, and allows images to be displayed in real time without radiation exposure, thereby having high safety. The ultrasound probe 6 further comprises a support frame 65. The support frame 65 is used for mounting the ultrasonic probe 6 on the inner side wall of the cup portion 1, and the sequence of the layers of the ultrasonic probe 6 from the detected organ to the inner side wall of the cup portion 1 is as follows: an acoustic lens layer 61, a matching layer 62, a piezoelectric sensor array layer 63, and a backing material layer 64, in this embodiment, the backing material layer 64 of the ultrasonic probe 6 is mounted on a support frame 65, that is, the piezoelectric sensor array layer 63 is located between the matching layer 62 and the backing material layer 64.
