3D MRI Brain Anatomy
3D MRI Brain Anatomy Mohamed 23,572 Views • 2 years ago

I call this technique deep rendering. I basically stacked graphical cross-sections (in this case, MRI rendering data), using proper increments and clip through them with the camera. This way I am able to explore all internal components in full 3D real-time.

I actually was able to figure out how to colorize different organs to help distinguish them apart from each other but couldn't get the shader to render real-time in Maya.

Pectus excavatum (hollow chest) deformity is not uncommon (sometimes mild and other times severe in its form). The chest deformity is often the source of self-consciousness for the patients while growing up. Several surgical techniques (Nuss procedure, Ravitch procedure, etc) are available.

Endoscopic Transgastric Pancreatic Necrosectomy using a Forward Viewing Echoendoscope

Pancreatic pseudocyst drainage was the first therapeutic application of EUS. The cyst is punctured under ultrasound guidance, contrast injected, and a guidewire inserted. Initial dilation to 8mm is performed over the wire The EUS scope is then exchanged over the wire for a forward viewing endoscope.... A second dilation to 18mm is performed. This enables entry of the endoscope into the cyst perform cystoscopy, debridement if necessary, and insertion of multiple large bore double pigtail stents. The curved linear array-or CLA—echoendoscope has oblique viewing optics located proximal to an oblique scanning transducer. The accessory exits from the shaft of the echoendoscope at an ablique angle, adjustable between 15 and 30 degrees. There are several technical limitations using this echoendoscope. The oblique angle of exit results in a weekend transfer of force when advancing the accessory, difficult deployment of larger bore accessories, and in instrument tunneling effect relative to the bowel wall. There is the potential loss of access during endoscope exchange. A novel CLA echoendoscope was developed by the Olympus Corporation that shifts the orientation of endoscopic and ultrasound views from oblique to forward viewing. The channel is therapeutic at 3.7mm Note that the working channel is located adjacent to the ultrasound transducer at the endoscope tip. The accessory exits the working channel in the axis of the shaft. Shown here are balloon inflation and deployment of a Dormia basket. We report on the use of the prototype forward viewing echoendoscope in six consecutive patients who were referred for pancreatic cyst drainage. Here you see endoscopic view-indistinguisable from that of a gastroscope-showing a bulge where the cyst impinges against the posterior gastric wall. Power Doppler is switched on and highlights multiple vessels interposed in the wall This allows selection of a safe vessel-free window for a cyst puncture A 19 G needle is advanced into the cyst lumen. A sample of contents is aspirated for fluid analysis. A guidewire under ultrasound guidance into the cyst. An 18mm balloon is coaxially thread over the wire and advanced across the cyst wall, Note that resistance is encountered, but the forward transfer of force overcome this. The dilation is performed under forward viewing endoscopuc and ultrasound guidance. As the balloon is maximally inflated we see the cystgastrostomy open up. The balloon is then deflated while simultaneously advancing the scope into the cyst cavity. Cystoscopy isnow performed showing the cyst contents to be filled with pasty wall-adherent necroses. Pulsed power Doppler is switched on we can see and hear arterial flow vessels within the wall of the cyst. This identifies sensitive areas at bleeding risk when performing debridement In this case vigorous water jet irrigation is performed through an accessory water irrigation channel built into the echoendoscope. This issued to clear nonadherent debris. Our experience has shown that it is not necessary to actively remove wall-adherent debris using extraction tools as such Dormia or Roth net basket to achieve cyst resolution. Three large bore 10 Fr double pigtail stents are now inserted into the cyst under direct endoscopic guidance. The first stent is delivered over a guide catheter. The second stent. And the third stent All three stents are deployed. Finally, a nasocystic catheter is inserted for maintenance irrigation. In another patient we used the Cook Cystome to perform cystgastrostomy. We have found the Cystotome easy to delivery through the forward viewing echoendoscope. As shown, we advance the Cystotome into the cyst while applying diathermy. This is performed under and endoscopic guidance, entering the cyst at a near perpendicular orientation. After entry, the Cystotome is removed and cyst fluid gushes from the cystagastrotomy site.
