The shade line tube of existing mammography machine is shorter, is up-small and down-big bullet, penetrates though reduced the width of cloth of a large amount of former lines of departure, still has the width of cloth of a large amount of secondary rays to penetrate, and safeguard function is poor, and influences the definition of photo.
The filter disc of existing tungsten target X line photographic attachment is 0.5-1.5mm, but the deleterious ray of absorption portion but be not suitable for mammary gland arteries and veins soft tissue, because of ray harder.
Existing homemade molybdenum target X line mechanical coke point face is big, and heat fusion joint is low, the X spool life-span short.
Minimum kilovolt of value of the power supply of existing common tungsten target X line machine can not provide mammography required 20-30KV for 40KV.
The anode angle of existing tungsten target X line machine is 20 °, and bigger for the irradiated area of mammary gland, the exposure rate of X line is also bigger, and effective focal spot is also bigger simultaneously, all is unfavorable for mammography.
The content of utility model:
It is low that the purpose of this utility model provides a kind of cost, and barrier propterty is good, the common tungsten target X line mammographic device that the photo definition is high.
This utility model is achieved in that
This utility model tungsten target X line mammographic device, the head 14 X spools 2 that are positioned on the frame 1 are connected with the output of power circuit, it is relative that anchor clamps 3 and cassette tray 4 are positioned under the head window 5 with head 14, the major axis and the horizontal plane of X spool 2 acutangulate angle, anode 6 infra of X spool 2, the target surface of anode 6 is towards anchor clamps 3 and cassette tray 4.
The major axis of X spool (2) points to human chest or parallel with human chest, and major axis becomes 4 °-12 ° angle with horizontal plane, be preferably 6 ° of-10 ° of angles.
The major axis of X spool 2 becomes 4 °-12 ° angle with horizontal plane, the projectional angle of anode 6 is the center that 8 ° the incident line is arranged in the magazine film, and the projectional angle of anode 6 is that 0 °-16 ° the incident line covers magazine.
The major axis of X line 2 becomes 6 ° of-10 ° of angles with horizontal plane, the projectional angle of anode 6 be 4 ° the incident line at the center of magazine, anodic projectional angle is that 0 °-8 ° the incident line covers magazine.
There is straight tubular shade line tube 13 to be connected with the end opening 8 of interface tube 7, suitable for reading 9 of interface tube 7 links to each other with window 5 on the head 14, the other end of shade line tube 13 is towards magazine, the axis of shade line tube 13 is vertical with film, have filter disc slot 10 to cooperate with filter disc 12 between the upper and lower interface of interface tube 7, filter disc 12 is the aluminium flake of 0.08-0.8mm for thickness.

This utility model is adjusted on the autotransformer of the low-pressure section of the power circuit of common X-ray machine, makes original minimum kilovolt (40KV) reduce to ultralow kilovolt (20-30KV), reaches the straight requirement of kilovar of mammography.Adjusted machine still has original function.
With the plate target face of original tube with W target,x-ray towards irradiation field, with the fixing downward-sloping 6-10 degree of the anode tap of X spool, make oblique fire wire harness that the 0-8 degree at plate target face tilt angle produced perpendicular to film, (and being different from original centrage) perpendicular to film thus obtain the gun parallax of X line output, compensatory to different-thickness before and after the mammary gland makes photographic film obtain uniform density.Improved the definition of mammary gland rear portion high density area.Shade line tube, the improvement of filter disc and X-ray tube make the definition height of mammography, and quantity of X-rays X is low.
This utility model is through the mammography inspection of 40,000 many cases and the homemade molybdenum target machine mammography contrast of the sick group of 10 examples, and its photographic quality surpasses the photographic effects of homemade molybdenum target machine.Owing to use the tungsten target X line mammography of improvement, its photo definition height, good contrast is for the diagnosis of breast carcinoma of early stage provides objective reliable foundation.Verify that with West China medical university cooperation its rate of cancerous diagnose early turns out to be 18.8% through pathology, is higher than the diagnosis of homemade molybdenum target machine.This utility model is the knotty problem that many hospitals even large hospital have solved some breast examination aspects, has been subjected to the approval of various big hospital mammary gland clinical medicine brainstrust, uses common homemade or import X line film, liquid medicine, contrast agent, intensifying screen etc. in this machine.As use the special-purpose intensifying screen of mammary gland special adhesive and mammary gland sheet, its effect is better, this utility model has overcome the deficiency of existing homemade molybdenum target machine, can reach the diagnosis effect of import mammary gland special machine again, but price is less than 1/10th of the import machine, meet the small-middle hospital equipment investment, this utility model is by provincial technical appraisement.
Tiltedly leak beam owing to adopt the anode effect utilization, make the tungsten target mammography reduce the skin dose of X line to the patient, through instrument test, totally four of everyone bilateral breast photographies, total X line dosage is 552 milliroentgens, is significantly less than limit the quantity of (the 1000-2000 milliroentgen number) of defined in the world.The X line skin that also is lower than simultaneously molybdenum target mammary gland machine is held up dosage.This project drops into little, and cost is low, and charge also low (charge be import mammary gland machine check price 1 half) is subjected to patient's welcome deeply.This machine can be accomplished a tractor serves several purposes, neither influences the common voltage photography and checks, has also opened up simultaneously and has adopted homemade common X-ray tungsten target machine to do the new road of mammary gland soft tissue radiography, thereby improved the utilization rate of common X-ray machine.Also increased new inspection item for hospital.Thereby bigger economic benefit and social benefit have been brought.
