 PIMPER, István: The 3D printing of the results of  medical diagnostic picture-making   (CII)


1.  The Invention



 The 3D printing of the results of  medical diagnostic picture-making  


The problem the inventor(s) wanted to solve

 Demonstrating 3D maps that were already visualized, eg. by  rotation, on monitor and worked out by softwares on medical diagostic machines (3D – 4D ultrasonic, CT, MRI, PET); it should provide real stereophonic experience in a simple form and be accessible by anyone.



 Flat picture (from postcard measure til poster measure) – suggesting moving picture impression – produced in printed form from pictures of medical diagnostic machines (3D-4D ultrasonic, CT, MRI, PET ), which is suitable for real stereophonic demonstration or visualization of the above mentioned machines’examination results. Furthermore, it is appropriate not only for stereophonic, but moving pictures and procedures taking place on time series as well.




For preparing the picture to be printed, one needs the series of pictures produced from the medical diagnostic machines’examination results. All of the machines are suitable for producing (by rendering) a picture rotated in space (cine-loop); this cine-loop is made from picture phases (e.g. 4D ultrasonic) or X-ray segments (scan) (e.g. CT,  Computer Tomograph) and can be visualized on the machine’s monitor (Pimper 1. figure). In this case, it is a cine-loop video extract produced by a  4D ultrasonic machine. The setting of the rotation parametres (step space, angle range) has to be performed in the adequate manner, because these parametres influence the quality of the end-product in a high extent. The few second long video extract is exported out from the machine (e.g. AVI file copying, DVD writing), and then it is dissociated to its picture items. These picture items will be the special (so called lenticular, lense plate) picture’s source. (Pimper  2a, 2b, 2n  figures show the two end points and the middle phase picture (2b)). A complex digital  substance is produced from the phase pictures by the help of a special software. This substance is used for making paper picture by a very high resolution photo printer. This picture is mounted on the back of the lense plate. However, pictures can be printed on the back of the lense plate by direct method and it is ideal for mass production of small size pictures.

The picture made by this method  can be inspected from several angles and, for the optical features of the lense lines, one is able to see different picture points, extracts. If the lenses are placed uprightly, our right and left eyes percieve different phase picture and the deepness impression is provided. (The prepared picture from two different views,  Pimper 3a, 3b figures.) No aid, e.g. eyeglasses,  is needed for reaching the impression.

Animation can be also produced from pictures taken out of time range, if we use the mentioned analogy. In this case, in order not to prevail the stereo effect of the two eyes, the lenses are placed horizontaly, and the picture is stirred uprightly. 

There is possibility of making small size  (min. size 3-4 cm), hand-holded picture (e.g. 3D fetus record), but bigger size, wall picture as well. Their size depends on the resolution of picture items taken out of the diagnostic machine. Maximum 25-30 cm pictures can be provided from 3D ultrasonic records, but 30x60-70 cm pictures can be made form CT records. The optimal watching distance, in order to achieve the stereoscope of the small size picture, is arm’s lenght. In case of wall pictures, it is 1-2 m.




It can be the new service of gynecological-obstretrical clinics, private surgeries for 4D examinations besides printed, traditional paper picture and video record. Hospitals, clinics can use it as scientific, educational-visual aid. The pictures are appropriate for placing them into brochures, or issues can be made out of this material. It can be commercial, PR marketing tool as poster, stopping board on exhibitions or at appliance dealers.

Applying on non-medical field: appropriate for visualizing real, 3D pictures made of archeological fossils, petrified objects (such as dinosaur egg, Pimper 4 figure. In this case, the exterior disturbing stone layer can be extracted by CT apparatus software. The already made 3D picture of a crab fossil would be astonishingly realistic and lifelike, Pimper5 figure




It can be applied easily, no aid is needed for achieving the stereophonic impression, it can be available for anybody and its psychic influence on the viewer is extremely high, too. For there are many built-in phase pictures and the stereophonic impression is realistic, its resolution and diagnostic value is higher than the traditional picture’s.

Pathological processes (e.g. growing tumour) can be introduced as animation, and in a simple way


Stage of development.

 The development has taken approximately 2 years. In order to achieve the aim, there was need for developing the lenticular technology (not so known in Hungary), which is an extremely high resoluting digital printing method.  I can provide the end  product in all fields and all sizes, and on the producing level. The producing procedure is performed by DigiPress Stúdió, HU-Veszprém (my own company), involving in subcontractor, if it is needed.
