Abstract
The present invention features that one X-ray forming and collecting mechanism rotates around the tested body in constant angular velocity to collect in different angles digital X-ray images, the images are processed to enhance the grey scale for soft tissue areas, stored in a computer memory and in correct order. When the images are playbacked in the correct order from some starting point, it is possible to observe a transparent body to show the relative positions and states of organisms and blood vessels, and this is favorable to improvement of medical diagnosis.
Description
The present invention relates to a kind of method of obtaining three-dimensional transparent digital x-ray image of the transparent stereo observation of realization inside of human body institutional framework in the ultrasound medicine.
X-ray is the main means of perspective tissue, is widely used in clinical diagnosis, but resulting video is the plane picture of perspective, and pair little inherent shortcoming of soft tissue contrast is arranged.And the CT faultage image remains plan view image, and the true form of design human internal organs also needs the three-dimensional visionary with the doctor.
The purpose of this invention is to provide a kind of by playing the digital X-ray plane picture of under different angles, being gathered that is present in the computing machine continuously by any direction, can realize the stereoscopy effect, its result is being as observing transparent human body, and can embody the method for obtaining three-dimensional transparent digital x-ray image of the relativeness between each organ and blood vessel in the body intuitively.
Above-mentioned purpose of the present invention is to realize by such technical scheme, it is a kind of method of obtaining three-dimensional transparent digital x-ray image, it is characterized in that: comprise that an X line with respect to the measured body rotation forms and collecting mechanism, X-ray digital picture by identical several different angles of differential seat angle rotation continuous acquisition, after image strengthened the soft tissue area gray level and handle, deposit computer memory successively in; With any storer has been to press any direction playing image successively.
Because the observation to object is to realize with the object transparent flat image of watching different angles.According to sense of rotation and the speed of rotation that the user selects, play the digital X-ray image of under different angles, being gathered in the computer memory continuously, reach the effect of observing transparent human body.
The present invention takes to play continuously the digital X-ray image of being gathered that is present in the computing machine under different angles, can realize observing directly the effect of transparent human body.And can embody the relativeness between each organ and blood vessel in the body intuitively, and due to illness form, the relative position of each organ and main blood vessel become the form that causes and change.Traditional plane X illumination light or the photo that compare enter three-dimensional stereo transparent human body image from the two-dimensional plane image, can obtain more information.And the CT faultage image remains plan view image.The straight real form of design human internal organs also needs the three-dimensional visionary with the doctor, and the present invention can intuitively show and can help the user to improve the medical diagnosis level by the stereoscopic three-dimensional image of organ in the human body.
The present invention can further specify by drawings and Examples.
The present invention has following accompanying drawing:
Accompanying drawing 1 is the synoptic diagram of X image acquisition of the present invention;
The synoptic diagram that accompanying drawing 2 is play continuously for X image of the present invention.
Referring to accompanying drawing 1: the X line among the figure form and collecting mechanism A with respect to measured body B with identical dA angle rotation, the X-ray digital picture of several different angles of continuous acquisition deposits among computer memory M0～n-1 successively.
Referring to accompanying drawing 2, with any storer, be starting point as Mn/2, press any direction, as clockwise direction playing image successively, obtain the dynamic 3 D image of measured body lung.
Differential seat angle dA of the present invention≤8 °, differential seat angle can eliminate the scintillation when image is play less than 8 ° the time.Acquisition rate is every width of cloth image 0.01-0.05 second.Picture resolution is 800 * 600,256 grades of gray levels, only need gather the image between 0 °～180 ° of the measured bodies, when adopting 5 ° of differential seat angles, can gather 32 width of cloth images, is left side view with the 0th width of cloth figure promptly, and the 16th width of cloth is front elevation, and the 31st width of cloth is a right view.The described enhancement process that soft tissue in the image of gathering is carried out can be undertaken by several curing patterns, also can carry out according to the self-defining enhancement mode of user.
As required, play the digital X-ray image that is present in process enhancement process in the computer-internal storer by the width of cloth by selected sense of rotation continuously apart from the distance of observation point, observe continuous digital X-ray image by the width of cloth, its result is as observing transparent human body.And can embody the relativeness between each organ and blood vessel in the body intuitively, and can easily image be amplified and dwindle.
Claims (2)
1. method of obtaining three-dimensional transparent digital x-ray image, it is characterized in that: comprise that an X line with respect to measured body B rotation forms and collecting mechanism, by identical differential seat angle dA rotation, the X-ray digital picture of several different angles of continuous acquisition, after image strengthened the soft tissue area gray level and handle, deposit computer memory successively in; With any storer has been to press any direction playing image successively.
2. the method for obtaining three-dimensional transparent digital x-ray image according to claim 1 is characterized in that: differential seat angle dA≤8 °, acquisition rate are every width of cloth image 0.01-0.05 second; Picture resolution is 800 * 600,256 grades of gray levels, only need gather the image between 0 °～180 ° of the measured bodies.
