Holographic Unborn Baby @BioHoloVideos

October 9th, 2015

This post was kindly inspired by Dr. Sébastien Barré, Institute of Topographic and Clinical Anatomy, University of Berne, Switzerland.

Enjoy an impressing baby! We offer a Holographic 3D video of an unborn, 32-weeks young, healthy and lovely baby imaged with 3D ultrasound and enhanced with a special GCM-denoising filter (GygerCattinMaloca).

The images are obtained with 3D ultrasound from a baby and freed from speckle-noise that may degrade the image quality.

NOte the grnaular ascpect that is caused by speckle-noise. After image processing with a special noise-filter, the contures appera better outlined and enhanced. ©2015 GETOCT™ Ltd.

3D Ultrasound imaging of a 34-weeks old, unborn baby (original versus GCM filtering). Only one cross sectional 2D image is shown to demonstrate the effect of speckle-noise removal in 3D ultrasonography. In the original image (left) a cross sectional, en-face ultrasound scan is shown. Both eyes, the nose and the mouth are visible. Note the granular aspect that is caused by speckle-noise. After image processing with a special noise-filter (Gyger-Cattin-Maloca filter, GCM), the contures appear better outlined and enhanced with preservation of the structure. ©2015 GETOCT™ Ltd. All rights reserved.

Speckle-noise may be a problem in a lot of medical imaging systems like ultrasound (US), computer tomography (CT), magnetic resonance imaging (MRI) or optical coherence tomography (OCT). In our OCT research laboratory (OCTlab) at the University of Basel, Switzerland, we developed a special filter to free a medical imaging volume from speckle-noise.

Rescued eye and yet in danger – ocular melanoma

July 5th, 2015

Eine 50 jährige Frau verlor ihr linkes Auge wegen einer ausgedehneten Netzhautablösung. Am besseren rechten Auge: doppeltes Pech! Sie hatte ein Melanom! Das Auge konnte gerettet werden.  Es wurde erfolgreich mit Protonen bestrahlt, der Tumor schrumpfte. Der Visus verblieb um 0.5, manchmal sogar 0.7, wenn die Sicca nicht ausgeprägt war. Nach Jahren trat dann leider Visusverlus auf 0.3 und Metamorphopsien. Was war passiert?

A female had lost her left eye because of an extended retinal detachment. In her right eye, she had a melanoma, that was cured with proton beam radiation therapy. Years later, loss of visual acuity occured, but why?

Godzilla has conquered Switzerland – Future King of the OCT Monsters?

May 21st, 2015

Be the first…?

We are very proud to be the first in Switzerland to say: the Japanese company Topcon has announced a new OCT device: TRITON.  The ancient Greeks called a god of the sea Triton. He was blowing on a snail shell to reignite hurricanes and to dominate the sea and all mariner. He could steer ships by his wish and thanks to his exceptional power.

Well, you may think, who should care,  just another OCT machine, again? But this time, stay still for some seconds and listen to the promising possibilities of  future OCTs, for the benefit of all ophthalmologists and patients.

On the first impression, well, it is just an ordinary medtech box, nice designed, compact and easy to operate. What else? Below the surface, as in the sea, a real treasure could be hidden. Japanese are world famous for their delicate fine arts and they may hide the true value.

TRITON seems to be very powerful, because it promises so much:

  • fastest OCT technology using 1050 nanometer SWEPT SOURCE OCT (SSOCT),
  • oversampling line scan 128 (!)
  • deep range imaging
  • en face OCT
  • vitreous visualization
  • accurate registration and tracking
  • standard color fundus imaging
  • Dye-free AngioOCT (angiography without fluorescein)
  • fundus autofluorescence (AF)
  • fluorescence angiography (FA)
  • anterior segment imaging with anterior segment lens
  • DICOM connectivity for a paperless office

If an OCT scanner in 2015 should have all these magic medtech tools by today, then it would be a monster like the famous Godzilla. Maybe, in some decades, we will say to our children: “… that once upon, there was a time, when ophthalmologists used a separate device for all their needs”.

Godzilla could not talk in the films, so, even we leave the words aside and show you brand new images from the very first “Swiss TRITON SSOCT” and the first AngioOCT images. Triton seems to be not a Swiss knife but an united origami of the most modern eye technology.

Rumors: Primus OCT 200: low cost OCT for everybody ?

May 6th, 2015

Zeiss India makes a great promise: an new OCT system that is cheap, easy to use and accessible for the small wallet. Well, everybody wants a cheap and easy to use OCT. Daniel Sims, Managing Director, Carl Zeiss India announced to the OCT world,  that Zeiss will offer a system with no gimmick,  that is focused on the OCT essentials. Thus, no run for the high end machines, but rather basics.

Primus OCT

Primus OCT. (C) Zeiss.

We will see,  if “Primus” will defeat his competitors and will be the first choice.

OCT Workshop Wien 2015

Die Optische Kohärenztomographie ist bei Erkrankungen des hinteren Augenabschnitts aus unserem Ordinationsalltag nicht mehr wegzudenken. Der Schwerpunkt unserer täglichen Leistungen liegt auf der individuellen Beratung und Betreuung unserer Patienten.

Viele stellen sich die Fragen:
•    Wie gehe ich mit meinen Glaukom- und Retinapatienten um und wie schleuse ich sie in einem effizienten Ablauf ein?
•    Welche praktischen Hilfsmittel gibt es bereits, um unseren Patienten eine personalisierte Versorgung zu ermöglichen und mir als Arzt und meinem Personal den Arbeitsablauf in meiner Ordination zu erleichtern?
•    Wo und wie bekomme ich Tipps und Tricks von erfahrenen Kollegen?

Floating in 3D-GETOCT 3D fanatasy is for you!

January 8th, 2015

Sie denken, das, was Ihre Augen Ihnen zeigen, ist wahr? Wirklich? Die richtige Welt ist aber gar nicht so, wie wir sie sehen. Die Welt “innen und aussen” ändern sich stets und Sie müssen eine Verbindung herstellen.

Schauen sie meinen Film und halten Sie den Atem an. Diese 3D GETOCT Phanatasie ist für Sie! 3D Phantasien sind “in” dieses Jahr. Schauen Sie, was vor Ihren Augen fliegt und sogar in Sie hineinrast, das es gar nicht gibt. Ihr Hirn betrügt Sie. Beachte: nichts, was Sie sehen ist wirklich wahr.

Genau so ist es mit den OCT-Bildern als Augenarzt: das Hirn diagnostiziert die Bilder sofort und Sie können sich vor einer “Diagnose” fast nicht wehren. Darum gibt es bei allen OCT-Bildern einen guten Tipp von Dr. Maloca: zurücklehnen, geniessen und warten bis die “OCT-Wahrheit” erscheint!

>Geniessen Sie (mit einer Rot-Cyan-Brille) und lachen Sie über Ihre Augen und Ihr Hirn und über dieses Wunder. /Watch (with Red-Cyan glasses)  and hold your breath. Just enjoy and smile about your eyes and brain showing you a miracle.

Ihr Dr. med. Peter Maloca, Luzern/Augenklinik Universität Basel

You think, what your eyes are showing you is true? Really? The world seems not to be what it is. The “inner” and “outer” world change and you have to connect.

This GETOCT 3D fanatasy is for you. 3D fantasies are in this year. Watch, what is passing before your eyes, that even does not exist. Your brain is fooling you. Realize: it is not really true what they say to you.  Still, this is the stuff your world is made off.

Not every OCT image is “true”.  The brain diagnoses the OCT  images immediately and you can almost not defend yourselve against a “diagnosis”. But there is a good and simple tipp from Dr. Maloca: sit back, relax and wait and wait until the ” OCT truth” appears!
