Title
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.
Description.
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.
Presentation.
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.
Application
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
Advantages
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.
