Description

A kind of Four-face four-dimensional color ultrasound
Technical field
The present invention relates to field of medical device, specifically a kind of Four-face four-dimensional color ultrasound.
Background technology
Holographic technique utilizes interference and diffraction principle record and the technology of the recording and reconstruction of the real 3-D view of reconstructed object.The first step utilizes principle of interference record object light-wave information, and this i.e. shooting process: subject forms the object beam of diffuse type under laser irradiation; Another part laser is as being mapped on holofilm with reference to light beam, produce with object beam superposition and interfere, the position phase of each point on object light wave and amplitude are converted to the intensity spatially changed, thus utilizes the contrast between interference fringe and interval to be recorded by the full detail of object light wave.The egative film that record interference fringe, after development, the handling procedure such as fixing, just becomes a hologram, or claims hologram; Its second step utilizes diffraction principle reconstructed object light-wave information, this is imaging procedures: the grating that hologram is complicated just as, under coherent laser illumination, the diffraction light wave of the sinusoidal pattern hologram of a linear recording generally can provide two and resemble, and namely originally resembles (also known as primary image) and conjugate image.The image third dimension reproduced is strong, has real visual effect.Every part of hologram all have recorded the optical information of each point on object, therefore its every part can reproduce the whole image of the original in principle, multiple different image can also be recorded on same egative film by multiexposure, multiple exposure, and can show respectively without interfering with each other.
Four-dimensional color ultrasonic devices is current state-of-the-art colorful ultrasonic equipment in the world." 4D " is the abbreviation of " four-dimension ".Fourth dimension refers to this vector of time, so be also referred to as real-time three-dimensional.For ultrasonics, 4D ultrasonic technique is that the revolutionary character of color ultrasound industry breaks through, and 4D ultrasonic technique adopts 3D ultrasonoscopy to add time dimension parameter exactly, and this revolutionary technology can Real-time Obtaining 3-D view, has surmounted the restriction of conventional ultrasound.It provide and comprise multi-field many-sided application such as abdominal part, blood vessel, organella, obstetrics, gynecological, urology department, neonate and department of pediatrics.Consequently: the Real-time and Dynamic live image that can show your unborn baby, or the real-time moving pictures of other human viscera organ.
At present, 3D/4D imaging on general medical ultrasonic diagnostic equipment is by the free-hand scanning of ordinary ultrasonic probe, volume probe or two-dimensional matrix probe scanning each section after, drawn or surface rendering data by three-dimensionalreconstruction organizator, imaging is carried out again by display, because display can only imaging face, therefore can only observe from an angle, directly perceived not, third dimension is not strong, lack verity, as other faces will be observed, the mode by rotating then is needed to transform visual angle, add operating procedure, and when rotating, volumetric imaging data also can change, often need to recalculate, add response time.
Summary of the invention
The present invention is just for above technical problem, and providing a kind of can directly process the 3D rendering that medical ultrasonic diagnostic device transmission is come, and is shown as the simple and easy Four-face four-dimensional color ultrasound of stereo-picture by holographic projecting screen.
The present invention is achieved through the following technical solutions.
A kind of Four-face four-dimensional color ultrasound, comprises the following steps:
One, acquisition volume data,
By the probe of medical ultrasonic diagnostic equipment, inspection area is carried out to the data acquisition of each tangent plane;
Two, slice of data is obtained,
By by the probe acquires of back medical ultrasonic diagnostic equipment to each tangent plane data graphically calculate, obtain the slice of data of inspection area;
Three, volume data is obtained,
The slice of data obtained by back carries out interpolation calculation according to the spatial relation of section, carries out three-dimensional reconstruction, obtains the volume data of physical location;
Four, volume data imaging,
By viewpoint being placed on the front of volume data that back obtains, the back side, the left side, the right side carry out projection imaging, obtains the imaging data on front, the back side, the left side, the right side;
Five, holographic imaging,
Line holographic projections display is carried out by the special display screen of Four-face four-dimensional color ultrasound.
The present invention also provides a kind of Four-face four-dimensional color ultrasound special display screen, comprise visualization module, holographic projecting screen, support frame, reflecting surface, it is characterized in that reflecting surface is polylith, polylith reflecting surface is arranged in support frame, holographic projecting screen is arranged on support frame top, visualization module is arranged on holographic projecting screen top, reflecting surface and holographic projecting screen angle at 45 °, volume data is mainly carried out tetrahedral projection by visualization module, and projected image is sent to holographic projecting screen display, reflecting surface is made up of the glass being pasted with holographic film, reflecting surface is four pieces, in pyramid.
Due to Four-face four-dimensional color ultrasound of the present invention directly volume data is projected from front, the back side, the left side, right side four direction after reappear, can arbitrarily observe from multi-angle diagnosis and treatment region, due to reflecting surface and holographic projecting screen angle at 45 °, therefore when projected image is sent by holographic projecting screen, being transferred on reflecting surface reflexes in human eye, and the mirror image that human eye is seen just feels it is the mirror image inside reflecting surface.From different specular observation to mirror position all the same, but viewing angle is different, consistent with real scene.
Structure of the present invention is simple, easy to use.
