Medical Imaging Update
We’ve been working with our client on this medical imaging system for over a year now. Our part (the 3D part, of course) is one element in a larger application. The entire system is developing very nicely. Here is the latest version of our 3D renderer for CT and MRI scans. What you see above is the most basic rendering: direct volume rendering with no coloring applied. Below is the same scan rendered from above. Keep in mind that the scan is rendered at interactive framerates, so the user can change all display settings and navigate around and in the scan in real time.
We’ve added in another rendering mode which can be useful for some scans: iso-surface rendering. This mode creates a more “solid” image of the data and allows us to do a few different kinds of effects compared to the direct volume rendering mode.
Notice the high-quality lighting. There are numerous lighting and coloring settings available for isosurface mode. Many of the same data manipulation controls are available in this mode as well. Here’s the same scan but we’ve now focused on on the pelvis and hip bones. You can see that the scan has a lot of data in it and that once we start exploring the inside of the body it gets quite jumbled. Don’t worry, a radiologist knows what they are looking at. Also notice a few lighting artifacts (bands and stairs) because even though this data has some better resolution than previous scans, it is still relatively low. For this entire abdomen there are only about 160 slices.
