Description

Multi-bulb tube irradiated breast imaging equipment

Technical Field

The utility model belongs to the technical field of breast formation of image, especially, breast image equipment that many bulbs irradiated.

Background

The DR system, i.e. a direct digital radiography system, is composed of an electronic cassette, a scan controller, a system controller, an image monitor, etc., and is a direct digital radiography system which directly converts X-ray photons into a digital image through the electronic cassette. In the direct digital photography in the narrow sense, DDR (digital Radiography), generally refers to digital Radiography using the image direct conversion technology of a flat panel detector, is a real direct digital X-ray photography system, and generates X-rays by impacting a target object with high-speed electron flow, the X-rays penetrate through a shot object and enter a flat panel detector (DR panel), the X-rays are converted into optical signals in the flat panel detector and then converted into electrical signals or directly converted into electrical signals (different conversion modes of DR panel materials), and finally recognized as digital signals, the digital signals are transmitted to a display computer, and the digital signals are analyzed, recognized and converted into pixel signals by software to form an image.

In the existing medical imaging field, a single bulb tube has large energy, large irradiation dose, long irradiation time and great harm to human body; the single bulb tube has large energy, large irradiation dose, long irradiation time and images for the service life of a single detector; the cost of a single bulb tube is high, the irradiation life time is long, and the service life of the bulb tube is influenced.

Breast diseases, particularly breast cancer, are a disease that afflicts women, the key to treating breast cancer is to find a focus in time at an early stage, and in order to realize accurate diagnosis of the focus, an imaging device is needed, and currently, an early screening mode for breast cancer is breast molybdenum target X-ray radiographic inspection. However, the molybdenum target X-ray examination is still two-dimensional imaging essentially, so that the judgment capability on the pathological changes of dense mammary glands is poor, the judgment on the pathological changes in the duct is not high, and the diagnosis needs to be confirmed by means of color Doppler ultrasound and other means. For patients with small breasts or cases with mammary gland hyperplasia, diagnosis is not easy, and misdiagnosis may occur.

Another method is Digital Breast Tomography (DBT) and contrast enhanced digital breast tomography (CE-DBT), which is characterized in that an X-ray tube ball rotates within a limited angle range (e.g., 10 ° -20 °) under the premise that the position of a detector is not changed, and dozens of high-resolution tomographic images can be obtained by low-dose exposure once per small angle (e.g., 1 °), and on the basis, three-dimensional image reconstruction is performed to improve the examination effect. However, this method still does not solve all the problems due to the limitation of the projection angle and the accuracy of image acquisition, and also, like the method, the examination procedure involves compression of the breast, causing discomfort to the patient.

Due to the limitations of the above two methods, it is often necessary to combine other different methods in clinic, such as breast ultrasound examination and breast magnetic resonance imaging for contrast examination based on breast molybdenum target X-ray radiography examination. Breast ultrasound examination has the advantage of being economical, simple and non-radioactive, but has the problem of difficulty in distinguishing many tiny foci of calcification. The breast magnetic resonance has strong capability of discovering the focus, can discover the tiny focus and identify the benign and malignant tumors, but the breast magnetic resonance equipment is expensive, high in examination cost and long in examination time, and is not suitable for patients after the cardiac pacemaker implantation; more importantly, the contrast agent is injected, which is not suitable for general screening.

The more conventional method is that a doctor uses a common imaging device to scan the breast, and the method has the problems that the conventional image scanning is to scan the whole breast tissue, not only the breast, so that the required radiation dose is larger; moreover, the resolution of the normal image is usually 0.5mm, which is not high enough in resolution.

More importantly, the focus of the bulb tube of the original mammary gland machine is too far away from the edge of the mammary gland, so that the root of the mammary gland cannot be shot, the root of the mammary gland cannot be shot when the mammary gland is shot, rays can be close to the root of the mammary gland to the maximum extent, the missed diagnosis can be avoided to the maximum extent, and corresponding equipment is not provided at present, and breast imaging equipment irradiated by a plurality of bulb tubes is not provided.
