Abstract
The utility model relates to a holographic display screen comprising an image displaying module, a holographic projection screen, a supporting framework, and reflection surfaces. The holographic display screen is characterized in that multiple reflection surfaces are provided and are disposed in the supporting framework, that the holographic projection screen is disposed on the top of the supporting framework, that the image displaying module is disposed on the top of the holographic projection screen, that intersection angles of 45 degree are arranged between the reflection surfaces and the holographic projection screen, that the image displaying module receives and processes 3D images transmitted from a medical ultrasonic diagnosis device and controls the holographic projection screen to display the images, and that the reflection surfaces are formed by glass coated with holographic films. The holographic display screen directly reproduces volume data from multi-direction visual angles. A diagnosis and treatment area can be observed from multiple angles arbitrarily. The holographic display screen with simple structure is easy to use.
Description
Technical field
The utility model relates to field of medical device, specifically a kind of holographic display screen.
Background technology
Holographic technique is to utilize interference and diffraction principle to record and reproduce the technology of the recording and reconstruction of the real 3-D view of object.The first step is to utilize principle of interference to 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 as being mapped on holofilm with reference to light beam, stack produces and interferes with object beam, position phase and the amplitude of each point on object light wave are converted to the intensity spatially changing, thereby utilize contrast and interval between interference fringe that the full detail of object light wave is recorded.Record the egative film of interference fringe after the handling procedures such as development, photographic fixing, just becoming a hologram, or claiming hologram; Its second step is to utilize diffraction principle to reproduce object light-wave information, this is imaging procedures: hologram is just as a complicated grating, under coherent laser illumination, the diffraction light wave of the sinusoidal pattern hologram of a linear recording generally can provide two and resemble, i.e. original elephant (claiming again initial image) and conjugate image.The image stereoscopic sensation of reproducing is strong, has real visual effect.Every part of hologram has all recorded the optical information of each point on object, therefore its every part can be reproduced the whole image of the original in principle, by multiexposure, multiple exposure, can also on same egative film, record a plurality of different images, and can show respectively without interfering with each other.
Four-dimensional color ultrasonic devices 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 be also known 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, the restriction that has surmounted conventional ultrasound.It provides multi-field many-sided application such as comprising belly, blood vessel, [Dan, obstetrics, gynaecology, urological department, neonate and paediatrics.Consequently: can show your unborn baby's real-time dynamic moving image, or other human viscera organ's real-time activity image.
At present, 3D/4D imaging on general medical ultrasound diagnostic device is by after the free-hand scanning of ordinary ultrasonic probe, volume probe or each section of two-dimensional matrix probe scanning, by three-dimensionalreconstruction organizator, draw or surface rendering data, by display, carry out imaging again, can only, from an angle, as observed other faces, need to transform visual angle by the mode of rotation, operate more time-consuming, directly perceived not from an angle observation, stereoscopic sensation is not strong, lacks authenticity.
Utility model content
The utility model, just for above technical matters, provides a kind of and can by a plurality of angles, observe the simple and easy holographic display screen of 3D rendering simultaneously.
The utility model is achieved through the following technical solutions.
A kind of holographic display screen, comprise video picture 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, and video picture module is arranged on holographic projecting screen top, reflecting surface and holographic projecting screen angle at 45 °, video picture module receives the 3D rendering that medical ultrasound diagnostic device transmits, and processes and controls holographic projecting screen and show image.Reflecting surface is comprised of the glass that is pasted with holographic film.Reflecting surface is four, is pyramid.Reflecting surface is three, is separately positioned on the left side, the right side, front.
Because holographic display screen described in the utility model is directly directly reappeared volume data from multi-direction visual angle, can arbitrarily from multi-angle, to diagnosis and treatment region, observe.
The utility model is simple in structure, easy to use.
Accompanying drawing explanation
In accompanying drawing, Fig. 1 is the utility model partial structurtes schematic diagram, wherein:
1-video picture module, 2-holographic projecting screen, 3-support frame, 4-reflecting surface.
