Barbara Duck informed us about a new development, NeuroTouch, that will hopefully lead to a new era in neurosurgery.

NeuroTouch, the prototype simulator developed by Canada’s National Research Council (NRC) and several other research groups, gives surgeons a dry run in virtual reality before entering the operating room, potentially reducing mistakes.

First, patient data from functional magnetic resonance imaging (fMRI) is rendered into a 3-D, high-resolution model of an individual’s brain. After the model is loaded into the system, doctors can touch and manipulate tumors and other virtual objects on screens in real time using a physical instrument resembling a scalpel. The instrument has six degrees of freedom and re-creates the force-feedback of the real tool and the varying resistance of tissue in brain regions with differing toughness. Meanwhile, photo-realistic on-screen imagery shows the simulated surgery, including bleeding and pulsing gray matter.

Magnetic Resonance Fail: More

I wrote about what happens when magnetic resonance meets ferromagnetic objects.  Here are a few other images:

Take care and follow the instructions of your MR device.

Radiopaedia: Section Editors Needed is a free online radiology resource built and maintained by it’s users. Section editors , as well as being regular users are responsible for overseeing part of the site, e.g. Gastrointestinal section. More information is available here. It is a great way to contribute to the site and radiology community in general, and you can also have something unique on your CV. Previous editors are of course remembered in the editor hall of fame.

This is a system Wikipedia should use as I’ve been saying for years.

They still have a few vacancies, and are therefore still accepting applications for the following positions.

  • gastrointestinal (GIT)
  • nuclear medicine (NM)
  • radiology physics
  • breast imaging
  • juniour trainee

Simply write to editors at with your CV and the section you are most interested in.

4 in 1: Video, podcast, photo and Pubmed

There are nearly 25 sites and services focusing on medical videos and animations on my list I’ve been working on for months. Here is the newest addition, The DAVE Project – Gastroenterology:

The DAVE Project, an acronym for the Digital Atlas of Video Education, is a collection of teaching tools. The project consists of a gastrointestinal endoscopy video atlas and medical lectures and presentations. The most recent additions to the collection are displayed below. Physicians are encouraged to submit material, for consideration, new entries to enrich and expand the atlas.

We can watch the videos or download them; listen to the podcast; see some related photos or do a Pubmed search in that specific field of interest.

DAVE stands for Digital Atlas of Video Education Gastroenterology…

MDPIXX Portal: Medical Media for Physicians

MDPIXX is a recently launched portal dedicated to medical media interchange between physicians. You have to be invited to join the community and share your medical images and cases and only registered physicians can invite you. An excerpt from their mission statement:


MDPIXX site allows worldwide physicians to interchange medical images and videos, create clinical cases, discuss and evaluate about them. All for free.

MDPIXX is a secure and private community for physicians. MDPIXX helps physicians to share and contrast clinical opinions about a case, improves medical research and help medical students to learn from experts by having a complete repository of clincial cases with associated media material.

MDPIXX is a closed community for physicians. Only physicians are allowed to post and comment a case. Clinical cases and associated images and videos are public to internet visits. MDPIXX doesn’t store any data about patients just the medical content of a clinical case. Content is responsability of each physicians.

They have more than 60 cases and 300 images now. Check out the collection of cases or the atlas. Below, you can see an example of how they present a medical case:


Medical Image Viewer: An Open-Source Project

What happens when you mix an innovative mind with some open-source projects? Greg Book can show you an example:

Medical Image Viewer (MIView) is an OpenGL based medical image viewer that contains useful tools such as a DICOM anonymizer and format conversion utility. MIView can read DICOM, Analyze/Nifti, and raster images, and can write Analyze/Nifti and raster images. It can also read and convert DICOM mosaic images. The main goal of MIView is to provide a platform to load any type of medical image and be able to view and manipulate the image.

My main goal is to create a simple and powerful program to provide useful visualization of medical images. Visualization methods will include planar views, orthogonal, multi-planar reconstruction (MPR), maximum intensity projection (MIP), volume rendering, and surface shaded display (SSD).

And you can download it for free. Kudos to Greg Book for his commitment to the medical community!
