Problems solved by technology
However, none of these methods can provide three-dimensional volume data of the breast, some cannot be observed in real time and multi-axial, some methods have no diagnostic significance, and some methods use X-rays that are harmful to the breast
X-ray CT breast scanning examination can provide three-dimensional volume data, and the diagnosis rate is high, but the examination is expensive and cannot be suitable for a large number of population censuses, and it is an indisputable fact that large doses of X-rays can damage the breast

Embodiment Construction
[0010] In Fig. 1, 2, the near-infrared light source (3) emits near-infrared light and transmits the scanned object (8) in the scanning frame (7) through the scanning frame entrance (6) through the light source front condenser lens (2); The near-infrared light transmits through the scanned object (8) and reaches the digital CCD camera (1). The near-infrared light source (3) is adjusted and controlled by the light-sensing feedback control circuit (11) to emit suitable light intensity; the anti-reflection grating (10) blocks the projection of near-infrared light The reflected light to the wall of the scanning frame (7) avoids affecting the detection of the transmitted light intensity by the digital CCD camera (1). When the near-infrared light intensity meets the data acquisition conditions of the digital CCD camera (1), the digital CCD camera (1) sends an instruction to the computer, and the computer program controls the servo motor (4) to start, and the transmission mechanism (5)...

The invention relates to a breast light cone beam rotary scanning imaging device. The upper edge of a cylindrical scanning frame is provided with a slide rail which is connected with a hole of a detecting bed surface with a corresponding dimension. A digital CCD vidicon, a close infrared ray source and a front condensing lens for the ray source are respectively mounted on a position opposite of one third section on the cylindrical scanning frame. The bottom part of the cylindrical scanning frame is provided with a transmission mechanism and is connected with a servo motor through the transmission mechanism. An optical induction feedback control circuit is arranged between the digital CCD vidicon and the close infrared ray source to control and adjust the close infrared ray source to emit a proper transmitted light intensity. When the transmitted light intensity meets the condition for the CCD vidicon to collect data, a command is instantly given out to a computer and the computer controls the servo motor to drive the scanning frame to rotate deasil or widdershins through the transmission mechanism. The digital CCD vidicon collects the breast data in real time and transmits the data to the computer to process and display a structural image in a breast gland in real time for diagnosing breast diseases.
Description
Technical field: [0001] The invention relates to a mammary gland light cone beam rotary scanning imaging device, especially a scanning imaging device that can rotate at least 180 degrees. Background technique: [0002] At present, the imaging examination methods for breast diseases include: X-ray mammography, B-mode ultrasonic scanning, cold light transillumination and other methods. However, none of these methods can provide three-dimensional volume data of the mammary gland, some cannot be observed in real time and multi-axial, some methods have no diagnostic significance, and some methods use X-rays that are harmful to the mammary gland. X-ray CT mammography examination can provide three-dimensional volume data and has a high diagnosis rate, but the examination is expensive and cannot be suitable for mass population census, and it is an indisputable fact that large doses of X-rays can damage the mammary glands. Invention content: [0003] In order to avoid the deficien...
