Description
Technical field
This utility model relates to be measured for diagnostic purpose, is specifically related to the size with radiodiagnosis instrument conjunction measuring health.
Background technology
Intervene operation because of its wound few, complication is low, the advantages such as indication is wide, deeply jointly favor by numerous doctors patient, and the location of pathological tissues, blood vessel, the measurement of range size is that treatment successfully ensures, DSA (Digital subtraction angiography, digital subtraction angiography) as its unique Image-aided instrument, the simple possible of measuring method, the accuracy of image calibration just seems particularly important.
1, in operation in the past, often adopt the method such as radiopaque operating forceps or conductor housing storing, font stickup during location, combining with human bone labelling judges, these methods waste time and energy first, second because of skin drawing displacement, location is inaccurate or unsuccessfully happen occasionally.
2, formed by computer mould number conversion reconstruction after human body because DSA image sends cone-beam x-ray by x-ray bulb, become image mostly to have magnification distortion, usually need accurate calibration magnification ratio, the actual size of pathological tissues and blood vessel could be measured, be beneficial to the selection for the treatment of equipment, calibration steps mainly contained 1. machine and carried ionization chamber function in the past, according to pathological tissues layer and operation table surface spacing, the automatic survey calculation of machine, 2. steel ball or one section of certain length seal wire is put outside, Measurement and calibration in proportion, 3. to compare measurement according to the diameter of conduit in interventional procedure.Shortcomings several is above: 1. pathological tissues and operating-table distance machine are defaulted as certain value automatically, and this distance can be had nothing in common with each other with the change of lesion locations in reality, result after its calibration often has error, 2.: though shortcoming 1. can be made up, but Preoperative Method is complicated, waste time and energy, 3. prerequisite be lesion vessels or tissue and conduit must in the same visual field and same level, but actual operation process often has lesion vessels tiny, conduit can not near diseased region, and pathological tissues or blood vessel and conduit can not ensure to be presented in the same image visual field.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of scale of locating for DSA image, measuring and calibrating, this scale can make the location of DSA image, calibration, measurement become precisely quick, thus shorten the intervene operation time, improve the success rate of intervene operation.
The scheme that this utility model solves the problems of the technologies described above is as follows:
The scale of locating for DSA image, measuring and calibrating, this scale comprises banded chi body, and it is characterized in that, described chi body is made up of the upper chi body be bonded together up and down and lower chi body, wherein,
The upper surface of described upper chi body is provided with equidistant graduation mark along its length, is provided with sequence number between two adjacent graduation marks;
On the upper surface of described lower chi body, position corresponding to graduation mark set on upper chi body is provided with point-like graduation mark, position corresponding to the odd number of sequence number set on upper chi body is provided with odd indexed, each odd indexed is all set in a circle, and the upper end of the point-like graduation mark of each odd indexed both sides is provided with point-like line; Wherein, described point-like graduation mark and point-like line are by the some composition equidistantly distributed, and the distance between the point of composition point-like graduation mark equals the distance formed between the point of point-like line; Described point-like graduation mark, point-like line, odd indexed and circle are lead metal material and make.
Owing to all adopting 10 system countings in people's daily life, therefore for the ease of understanding and reading, this utility model preferred version is, distance between described graduation mark is 10 ㎜, the diameter of described circle is also 10 ㎜, and the distance formed between the point of described point-like graduation mark and the point of composition point-like line equals 2 ㎜.
From the such scheme of scale described in the utility model, due to the point-like graduation mark on described lower chi body, point-like line and odd indexed are opacity lead metal material and make, therefore described scale is placed in pathological tissues same plane, when carrying out DSA imaging together with human body, point-like graduation mark on described lower chi body, point-like line, odd indexed and circle just develop on same width DSA image with tissue, like this can not only on DSA image direct reading, and blood vessel under x-ray unspecified angle can be provided, the calibration scale value of tissue image, i.e. normotopia dot spacing, loxosis circle diameter image distance (make circle and be shown as ellipse by loxosis throwing, keep measuring radial line parallel with ellipse diameter).
Accompanying drawing explanation
Fig. 1, Fig. 2 and Fig. 3 are a specific embodiment structural representation (blocking enlarged drawing) of the scale located for DSA image, measure and calibrate described in the utility model, wherein, Fig. 1 is front view, and Fig. 2 is upward view, and Fig. 3 is A-A sectional view of Fig. 2.
Detailed description of the invention
See Fig. 1 ~ 3, the chi body of this routine described scale to be length be band shape of 80 ㎝, this chi body is made up of the upper chi body 1 be bonded together up and down and lower chi body 2.
See Fig. 1, the upper surface of described upper chi body 1 is provided with the graduation mark 1-1 that distance equals 10 ㎜ along its length, is provided with sequence number 1-2 between two adjacent graduation mark 1-1.
See Fig. 3 and Fig. 1, on the upper surface of described lower chi body 2, position corresponding to graduation mark 1-1 set on upper chi body 1 is provided with point-like graduation mark 2-1, position corresponding to the odd number of sequence number 1-2 set on upper chi body 1 is provided with odd indexed 2-2, each odd indexed 2-2 is all set in a diameter and equals in the circle 2-3 of 10 ㎜, and the upper end of the point-like graduation mark 2-1 of each odd indexed 2-2 both sides is provided with point-like line 2-4; Wherein, described point-like graduation mark 2-1 and point-like line 2-4 forms by the point of 2 ㎜ such as distance; Described point-like graduation mark 2-1, point-like line 2-4, odd indexed 2-2 and circle 2-3 make by lead metal material.
The using method of the scale located for DSA image, measure and calibrate described in the utility model is illustrated below in conjunction with accompanying drawing.
1, the application in spinal artery radiography location: be affixed on by patient's back spinal column by arbitrarily perpendicular for scale, the lower odd indexed 2-2 corresponding relation that can directly obtain on each vertebral body and scale of perspective, then the ordering relation of each spinal artery manifests one by one.
2, the application in arteriocerebral angiography: scale is fixed on by head, and make scale identical with blood vessel height, then carry out DSA image collection.Need not meticulous measurement time, patient only needs to observe the lead metal dot spacing of point-like graduation mark 2-1 or point-like line 2-4, can estimate the size of pathological tissues or blood vessel.When needing meticulous measurements, then can to compare measurements according to the diameter projected of described circle 2-3, when x-ray bulb oblique projection, circle 2-3 is shown as ellipse, only need keep measuring radial line and ellipse and calibrate diameter parallel and can obtain precise information.3, the application in ventral aorta, coronary artery peripheral blood vessel: equally scale is placed in pathological tissues or blood vessel same plane, after image collection, with the spacing of the lead metal point of same position composition point-like graduation mark 2-1 or point-like line 2-4 for comparison basis value, for reducing the error of range estimation, the spacing (1CM integral multiple) of the multiple lead metal of desirable major axis carries out calibration measurement, can ensure that result is consistent with reality.
