Abstract
The utility model discloses a digital image detector, which comprises a scintillator, a reflector and a charge-coupled device imaging device, wherein the light generated by the scintillator is reflected to the charge-coupled device imaging device through the reflector, and the incident light of the light generated by the scintillator and the normal of the reflector form an angle of 22.5 degrees. Since the incident light of the light generated by the scintillator and the normal of the reflector form an angle of 22.5 degrees, the charge-coupled device imaging device (CCD) is closer to the IP board, thereby, the structure is compact. The light reflecting to the IP board is reduced and the image quality is ensured.
Description
Technical field
This utility model relates to medical imaging device, and particularly a kind of CCD of utilization does the unitary digitized video detector of imaging.
Background technology
CCD is the abbreviation of Charge Coupled Device (CCD) (Charge Coupled Device), and it uses a kind of semi-conducting material of ISO to make, and can be transformed into electric charge to light, converts digital signal to by the analog-digital converter chip.At present CCD has been widely used in every field, such as mobile phone, digital camera, DV, medical imaging device DR etc.The CCD-DR detector technology is one of mainstream technology of DR product employing in the world at present.
Current, the light-path of the imaging of CCD-DR and other digitized video detector is, X ray is mapped to scintillator (IP) and goes up the generation visible light, the visible light that produces incides on the reflecting mirror, then by mirror reflects imaging on CCD and the digital circuit, incident illumination adopts and becomes 22.5 ° with the mirror normal, makes the CCD position nearer from the IP plate, makes the entire product compact conformation.
Summary of the invention
For solving in the prior art, the CCD position is far away from the IP plate in CCD-DR and other digitized video detector, the deficiency that the entire product structure is not compact, and this utility model provides a kind of digitized video detector of compactness.
This utility model in order to realize the technical scheme that its technical purpose adopts is: a kind of digitized video detector, comprise scintillator, reflecting mirror and Charge Coupled Device (CCD) imaging device, to described Charge Coupled Device (CCD) imaging device, the incident illumination of the light that described scintillator produces becomes 22.5 ° with the normal of reflecting mirror to the light that described scintillator produces by mirror reflects.
The incident illumination of the light that produces owing to the IP plate as scintillator in this utility model becomes 22.5 ° with the normal of reflecting mirror, reduces light and reflexes on the IP plate, makes Charge Coupled Device (CCD) imaging (CCD) setting position nearer from the IP plate, can make compact conformation.
Below in conjunction with the drawings and specific embodiments this utility model is done comparatively detailed description.
Description of drawings
Accompanying drawing 1 is this utility model embodiment 1 passage of light sketch map.
Among the figure: 1, scintillator, 2, reflecting mirror, 3, the Charge Coupled Device (CCD) imaging device, 4, incident illumination, 5, reflected light, 6, the reflecting mirror normal.
The specific embodiment
Claims (1)
1. digitized video detector, comprise scintillator (1), reflecting mirror (2) and Charge Coupled Device (CCD) imaging device (3), the light that described scintillator (1) produces reflexes on the described Charge Coupled Device (CCD) imaging device (3) by reflecting mirror (2), it is characterized in that: the incident illumination of the light that described scintillator produces becomes 22.5 ° with the normal of reflecting mirror.
