Abstract

The utility model discloses a CT machine for realizing no-traumatic pathological diagnosis using synchronous radiating light source, comprising both some main parts which comprise a radiation source system, a front collimating device, a gantry, a gantry, a detector, an A-D converter, an array control unit, a digital electronic computer, an operator's console, a monitor, and a compact disc machine or a magnetic tape, and some auxiliary devices which comprise an examining table, etc. The radiation source system is a small-sized or medium-sized synchrotron radiation X-ray resource system. The utility model increase the spatial resolution of scanning means to 1 micrometer to 1 decimicrometer which is required by the pathological diagnosis and realizes the diagnostics no-wound, and also provides dynamic and no-wound research methods for the development biology which is involved with the cell interaction and other micromorphology field.

Description

The application of synchronized radiating light source is realized the CT machine of non-invasive pathological diagnosis

Technical field

This utility model belongs to the research tool of medical diagnostic equipment or life sciences, and a kind of CT (CT scan) is provided machine, and particularly the application of synchronized radiating light source is realized the CT machine of non-invasive pathological diagnosis.

Technical background

The CT machine, except that common X line CT, PET (positron CT), the SPECT (spc) in addition that have now come out, because its collimation, collimation that scans used ray is poor, the spatial resolution of above-mentioned CT machine imaging (differentiating 2 minimum range) all is the millimeter level at the most ^[1]So, not only can not carry out the pathology typing to tumor, and, even to whether tumor does not have the meaning of making a definite diagnosis yet.Many tuberculosis hypertrophy mistakes are made pulmonary carcinoma, make the evaluation of oncotherapy lose basic prerequisite, and China thoracic surgery educational circles that has the most large pulmonary carcinosis example but cannot take out the gratifying card achievement of following in the world ^[2]And, because the difference of pathology typing is then correspondingly to the sensitivity difference of chemotherapy, radiotherapy, the difference of good evil degree is the excision extension difference then, feasible operation is that main Comprehensive Treatment exists very stubborn problem: the one, and get biopsy earlier and make pathology and perform the operation again, increase wound aggressive and patient's psychology and economic load, and get biopsy and also may make the malignant cell diffusion; The 2nd, have minority person lack of standardization do not do biopsy at once what radical correction, enlarge radical correction, make some benign tumor patients increase wound, dysfunction and pattern incompleteness (as optimum breast tumor) for no reason and cause medical tangle; The 3rd, neurosurgery is because the particularity of intracranial tumor, makes that the biopsy meaning is limited before the art, and minority is opened cranium and can't be excised and be forced to out cranium; And if any the pathological diagnosis of opening before the cranium, then operation of opening cranium may be changed into Minimally Invasive Surgery and carry out radiotherapy, electrochemotherapy or get involved chemotherapy.In a word, the noinvasiveization of realization pathological diagnosis is pressing for and inevitable trend of clinical medicine development.Because the millimeter class resolution ratio of existing CT machine can't satisfy the demand of clinical middle pathological diagnosis, therefore must adopt new scanning means to solve.

Goal of the invention

This utility model purpose provides a kind of CT machine with sufficiently high spatial resolution, thereby can carry out pathological diagnosis by it, also promptly realizes the noinvasiveization of pathological diagnosis.

Summary of the invention

For achieving the above object, this utility model is used small-sized or medium-sized synchrotron radiation X light source (large-scale light source inconvenience is implemented) system as the radiographic source system in the CT machine structure, thereby with the synchrotron radiation X light beam of the height of its generation collimation as the scanning means, make the spatial resolution of CT machine can reach micron order, thereby satisfy the needs of pathological diagnosis to branch micron (i.e. 100 nanometers) level.On the outer end of the ray output channel in the described synchrotron radiation X light-source system and the gantry inherent before collimator fixedly be connected, thereby the light path of the two is communicated with naturally.

Beneficial effect

One, this utility model resolution that will scan means is brought up to the needed degree of pathological diagnosis, thereby has realized the noinvasiveization of pathological diagnosis first.Two, promote the scientific and improvement of pathology typings such as tumor, diagnosis makes the hydrostatic pressure cerebral edema as cranium brain XCT ^[3]Be different from traditional cerebral edema (Therapeutic Principle's difference).Three, the breakthrough for life sciences provides new research means, relies on the discovery of X-ray diffractive technology to the dna double helical structure as the middle of last century, has once opened up molecular biology epoch.The cell interaction that developmental biology relates to can obtain morphologic, dynamic understanding by means of this utility model.

Fig. 2 is: the outside drawing of one of this utility model embodiment

Wherein 1, small-sized or medium-sized synchrotron radiation X light-source system, 2, the ray output channel in the synchrotron radiation light origin system, 3, preceding collimator, 4, gantry, 5, detector, 6, analog-digital converter, 7, array processor, 8, digital computer, 9, operating console, 10, monitor, 11, CD player or magnetic tape controller, 12, the screw hole that sets firmly of ray output channel outer end and preceding collimator, 13, bolt.

Embodiment

This utility model is made up of auxiliary devices such as critical pieces such as radiographic source system (being small-sized or medium-sized synchrotron radiation X light-source system 1), preceding collimator 3, gantry 4, detector 5, analog-digital converter 6, array processor 7, digital computer 8, operating console 9, monitor 10 and CD player or magnetic tape controller 11 and examinating couches.The existing abroad goods (IBM-2 type) of its middle-size and small-size or medium-sized synchrotron radiation X light-source system 1, other is the prior art structure of existing CT machine; And being connected between small-sized or medium-sized synchrotron radiation X light-source system 1 and the preceding collimator 3, the outer end by ray the output channel 2 and preceding collimator on the gantry 4 is fixing the light path of the two is communicated with naturally after being connected (the radiographic source system there is no substantive difference with being connected of preceding collimator in this point and the existing CT machine) can implement; Described fixedly bridging mode is removable fixedly connected, and embodiment as shown in Figure 2 also can be non-disconnectable connected mode, as the welding etc.When using this utility model, patient's (diseased region) is placed on the examinating couch in the cavity of gantry 4, diseased region is carried out tomoscan, particularly carries out wherein preferred target CT scan mode ^[4], can be met the image of the desired spatial resolution of pathological diagnosis.
