Bowl-type photoacoustic imaging breast scanning device and scanning method thereof

Abstract

The invention provides a bowl-type photoacoustic imaging breast scanning device and a scanning method thereof. The bowl-type photoacoustic imaging breast scanning device comprises a bowl-type photoacoustic probe, wherein the bowl-type photoacoustic probe comprises a bowl-type outer support, a laser beam expander is arranged outside the outer support, the inner wall of the outer support is an inner diffuse reflection cavity wall, and an ultrasonic transducer is arranged on the inner diffuse reflection cavity wall. During scanning, the a ultrasonic coupling agent is injected into the bowl-type photoacoustic probe, a breast to be detected is put in the bowl-type photoacoustic probe, the light from a laser is introduced into the bowl-type photoacoustic probe through a reflecting mirror and expanded, the photoacoustic signals at different angles are detected by the ultrasonic transducer and transmitted to a processor where a three-dimensional photoacoustic image of the breast is formed. By the photoacoustic imaging technique in combination with the routine ultrasonic imaging technique, the non-invasive portable photoacoustic imaging breast scanning device can rapidly scan and image breasts with high contrast and high precision and depth and achieve non-invasive and non-radioactive early diagnosis and treatment of breast cancer.

Description

technical field [0001] The invention relates to the field of ultrasonic imaging diagnostic devices, in particular to a bowl-type photoacoustic imaging breast scanner and a scanning method thereof. Background technique [0002] Breast disease, as a common and frequently-occurring disease in women, has attracted more and more attention. One of the main goals of modern breast medicine is to reduce the diagnosis of breast lesions by mammary gland biopsy. The most commonly used mammography imaging techniques are: [0003] Mammography uses soft rays to penetrate the soft tissue of the breast to achieve the purpose of diagnosing the tissue within the breast. It is characterized by simplicity, speed, painlessness, and high accuracy. It plays an important role in the diagnosis of breast hyperplasia, breast adenoma, breast cyst, breast cancer, etc. It is one of the most commonly used examination methods in breast surgery. Mammography is the most accurate imaging method for preoperat...

AI Technical Summary

Problems solved by technology

However, the limitations of MRI in breast examination are not sensitive to tiny calcifications. In addition, MRI is multi-sequence imaging, which is relatively complicated and takes a relatively long time. At the same time, it is interfered by respiratory motion artifacts, which affects the image quality to a certain extent. Limiting its promotion and application

At present, my country's MRI examination of breast is still in the research stage, the diagnosis experience is relatively insufficient, and MRI examination is expensive, and the accuracy of breast cancer diagnosis is only 39%, which is significantly lower than conventional mammography. There are still some difficulties in qualitative diagnosis after examination, which has caused a great economic burden on patients

[0007] From the above, it can be seen that the current conventional breast scanning imaging technologies have their own defects, especially in terms of imaging resolution and diagnostic accuracy.
