Description

Enclose fender structure

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to an enclose fender structure.

Background

Accurate diagnosis of breast cancer at an early stage is the key to the treatment of breast cancer. Conventional breast imaging systems include molybdenum target X-ray examination, breast ultrasound imaging technology, and Magnetic Resonance Imaging (MRI) examination, in which the sensitivity of the molybdenum target has a strong dependence on the density of the breast. Breast ultrasound imaging is problematic in detecting very small tumors, does not distinguish between benign and malignant tumors, and is very dependent on the experience and technique of the operating physician. MRI imaging has long imaging time and is too sensitive, so that the MRI imaging is not suitable for patients with metal objects in the body.

With the rapid development of molecular imaging technology in recent years, the functions of imaging technologies such as Positron Emission Tomography (PET), optical/fluorescence imaging and the like, which can realize functional imaging and molecular specific imaging, in early accurate detection of tumors are becoming more and more important. Several research units developed PET systems (PEM) specifically for breast detection. Published data indicate that PEM has 90% sensitivity and 86% specificity in detecting breast malignancies, and PEM has better spatial resolution and higher detectability than PET/CT for tumors smaller than 1 em. PEM is mainly imaged through 18F-FDG by utilizing the characteristic of tumor metabolism exuberance, but partial acute or chronic inflammation can also cause the metabolism exuberance so as to cause the false negative problem of PEM detection, and some tumors with relatively slow metabolism, such as lobular carcinoma, can cause the missed detection of PEM.

The discovery of the 650-950nm near-infrared window in 1999 and the subsequent development of near-infrared optical imaging technology, the diagnosis of early breast tumors using near-infrared light has become a hot point of research. Research teams of professor Brian Pogue and professor Keith Paulsen of the university of Dalmatian of America have carried out long-term and deep research work in the aspect of optical imaging of mammary glands, and in recent years, the research teams are dedicated to the research of near-infrared mammary gland optical imaging of wide spectral bands, and in 2014, the research teams adopt a detection array combining a photomultiplier tube and a photodiode to realize the combined detection of 6 spectral bands of a frequency domain and 3 spectral bands of continuous waves, so that good imaging results are obtained.

The near infrared diffuse light imaging technology is the leading technology in the field of medical imaging, and is suitable for diagnosing breast cancer (especially early breast cancer). Some breast cancer detection instruments adopt a near infrared diffused light imaging system, but the light obtained by a camera of the detection instrument is not only transmitted light passing through breast tissues, but also other light, which causes interference, and the detection result is inaccurate.

Because the shape of the human mammary tissue is irregular and the shapes of different human mammary tissues are different, the detection data obtained by direct detection is not beneficial to the reconstruction of the image, the calculation amount in the subsequent algorithm analysis process is large, the calculation time is long, and the result is not necessarily accurate.
