Abstract
The invention relates to four-face four-dimensional color ultrasound and a display screen special for the four-face four-dimensional color ultrasound. The display screen special for the four-face four-dimensional color ultrasound comprises an image displaying module, a holographic projection screen, a supporting framework and reflecting surfaces. The reflecting surfaces are composed of glass, wherein holographic film is pasted on the glass, the number of the reflecting surfaces is four, and the reflecting surfaces are of a pyramid shape. Due to the facts that the four-face four-dimensional color ultrasound directly conducts projection on body data from the front side, the back side, the left side and the right side and then reproduce the body data, and observation can be conducted in a diagnosis and treatment area from multi-angle view. The positions of mirror images observed from different mirror surfaces are identical, but the observation angles are different and are consistent with a real scene. The four-face four-dimensional color ultrasound is simple in structure and convenient to use.
Description
Technical field
The present invention relates to field of medical, specifically is the four-dimensional color ultrasound in a kind of four sides.
Background technology
Holographic technique is to utilize to interfere and diffraction principle record and the record of the real 3-D view of reproduction object and the technology of reproduction.The first step is to utilize principle of interference record object light-wave information, and this is shooting process: subject forms the object beam of diffuse type under laser irradiation; Another part laser is mapped on the holofilm as the reference light beam, stack produces and interferes with object beam, position phase and the amplitude of each point on the object light wave are converted to the intensity that spatially changes, thereby utilize contrast and interval between interference fringe that the full detail of object light wave is noted.The egative film that is recording interference fringe through handling procedures such as developments, photographic fixing after, just become a hologram, or the title hologram; Its second step is to utilize diffraction principle to reproduce the object light-wave information, this is imaging procedures: hologram is just as the grating of a complexity, under coherent laser illumination, the diffraction light wave of the sinusoidal pattern hologram of one bracing cable record generally can provide two and resemble, i.e. original elephant the (claiming primary image again) and conjugate image.The image third dimension of reproducing is strong, has real visual effect.Each part of hologram has all recorded the optical information of each point on the object, so its each part can both be reproduced the entire image of the original in principle, can also record a plurality of different images at same egative film by multiexposure, multiple exposure, and can show respectively without interfering with each other.
Four-dimensional colorful ultrasonic diagnostic apparatus is state-of-the-art colorful ultrasonic equipment in the world at present." 4D " is the abbreviation of " four-dimension ".Fourth dimension refers to this vector of time, so also be known as real-time three-dimensional.For ultrasonics, the 4D ultrasonic technique is that the revolutionary character of color ultrasound industry breaks through, and the 4D ultrasonic technique adopts the 3D ultrasonoscopy to add the time dimension parameter exactly, and this revolutionary technology can be obtained 3-D view in real time, has surmounted the restriction of conventional ultrasound.It provides multi-field many-sided application such as comprising abdominal part, blood vessel, organella, obstetrics, gynecological, urology department, neonate and department of pediatrics.Consequently: can show your unborn baby's Real-time and Dynamic live image, perhaps other human viscera organ's real-time activity image.
At present, 3D/4D imaging on the general medical ultrasound diagnostic device is by the free-hand scanning of ordinary ultrasonic probe, after each section of volume probe or two-dimensional matrix probe scanning, draw or the surface rendering data by the three-dimensionalreconstruction organizator, carry out imaging by display again, because display can only face of imaging, therefore can only observe from an angle, directly perceived inadequately, third dimension is not strong, lack verity, as observing other faces, then need to transform the visual angle by the mode of rotation, increased operating procedure, and rotation time, the three-dimensional imaging data also can change, and often need to recomputate, and have increased response time.
Summary of the invention
The present invention provides a kind of 3D rendering that can directly the medical ultrasound diagnostic device be transmitted to handle just at above technical problem, and is shown as the four-dimensional color ultrasound in simple and easy four sides of stereo-picture by holographic projecting screen.
The present invention is achieved through the following technical solutions.
The four-dimensional color ultrasound in a kind of four sides comprises following a few step:
One, acquisition volume data,
By the probe of medical ultrasound diagnostic device, the inspection area is carried out the data acquisition of each tangent plane;
Two, obtain slice of data,
Graphically calculate by each tangent plane data that the probe with back medical ultrasound diagnostic device collects, obtain the slice of data of inspection area;
Three, obtain volume data,
The slice of data that back is obtained carries out interpolation calculation according to the spatial relation of cutting into slices, and carries out three-dimensional reconstruction, obtains the volume data of physical location;
Four, volume data imaging,
Carry out projection imaging by the front, the back side, the left side, the right side that viewpoint are placed on the volume data that back obtains, obtain the imaging data on front, the back side, the left side, the right side;
Five, holographic imaging,
Carrying out line holographic projections by the holographic display screen of special use shows.
The present invention also provides the four-dimensional color ultrasound in a kind of four sides special-purpose display screen, comprise video picture module, holographic projecting screen, support frame, reflecting surface, it is characterized in that reflecting surface is polylith, the polylith reflecting surface is arranged in the support frame, holographic projecting screen is arranged on support frame top, and the video picture module is arranged on holographic projecting screen top, reflecting surface and holographic projecting screen angle at 45, the video picture module is mainly carried out the four sides projection with volume data, and projected image is sent to the holographic projecting screen demonstration.Reflecting surface is made up of the glass that is pasted with holographic film.Reflecting surface is four, is pyramid.
Since the four-dimensional color ultrasound in four sides of the present invention directly with volume data from the front, the back side, the left side, right side four direction carries out reappearing after the projection, can arbitrarily observe the diagnosis and treatment zone from multi-angle, because reflecting surface and holographic projecting screen angle at 45, therefore when projected image sends by holographic projecting screen, be transferred to and reflex on the reflecting surface in the human eye, the mirror image that human eye is seen just feels it is the mirror image of reflecting surface the inside.All the same from the observed mirror position of different minute surfaces, but the viewing angle difference is consistent with real scene.
The present invention is simple in structure, and is easy to use.
