Here it is, the entry you've been waiting for -- the workstation face-off liveblog! For those new to blog readership, here's how liveblogging works: I'll update this entry continuously throughout the face-off, with my newest updates appearing at the top. Keep refreshing to stay on top of all the action!
TeraRecon's up next. The presenter opens it up in a CTA protocol; the system removes the table and bone automatically as Dr. Herzog cleans up the image a little bit. Now he's isolated the vessels and is cutting away an artery, then moving to the MIPS view and windowing through to show the kidney stone. Saving and closing out, he logs on again as the "doctor," quickly reloads the image and indicates how to restore the missing vessel.
Philips. The dataset loads in a few seconds. Cleaning up the data, the presenter goes deeper into the program to show the automatic segmentation to display the different vessels and the kidney stone. He adds in a few seed points -- "I don't really do this ever, I'm just trying to be fancy," he stresses -- then names the image "stone" and saves it. Going back a step, he cuts out some vessel and a chunk of kidney, his intentional error, then shows how the saved dataset can be moved around his network. Booting back up as the doc, he reloads his work -- it takes a few seconds longer than the others -- then demonstrates how to restore the vessel and kidney piece. It takes a while to pop up . . . and time's up before it displays. Bummer!
GE's back. Loading the protocol, Dr. Wolff shows how the machine does all the work in terms of extracting the arteries and getting rid of the bones. The window automatically populates within five seconds or so. With no user input, the system has isolated the main arterial tree. He marks what looks like a kidney stone, then mags up the image to pivot around the stone, creating a nice view of the kidney. He saves it, then windows through the vascular view and has the computer automatically select the arterial tree he's interested in, displaying the four renal arteries on the right in a bright, colorful view. He removes a small vessel, then saves again (calling the file "junk," BTW). He exits, then boots up again to play the radiologist role, with 30 seconds to spare . . . he restores the missing vessel with just seconds to spare!
Next up: Dr. Tanenbaum for Vital Images. He preselects portions of the vessel right at the beginning, then zooms in on his 3D model to display the arterial tree as he tries to remove the noise. Whoops -- he accidentally messed up the model in the process . . . Moving on, he zooms in on the renal arteries, then does what he imagines a 3D tech would do and marks the renal arteries in a 2D view. He creates his error and removes a piece of vessel, then snaps the view, sends it to the server and moves on to the physician phase. In the "reading room," he restores the workflow from the server -- 30 seconds to go! -- and clicks on the vessel to restore it in 3D. Ta da!
Dr. Mendel's up first, for Ziosoft. In his aortic aneurysm protocol he lets the system automatically remove the bones and table, then cleans up the image a little bit by selecting the arterial tree. A bit of a blip here -- the system doesn't seem to want to cooperate and the clock is ticking . . . ah, there it is. Okay. Now we can see that there is no AAA, but now he needs to grow back the vessels in the patient's leg. Okay, now we're saving the image and going back to 3D analysis, window and level . . . he's picking a thick slab showing the renal arteries, then "accidentally" removing some vessels. He saves the file, then re-loads it, now in the role of the physician. He grows the vessels back, visualizing all the renal vessels. And with seconds to spare!
Case 3: Genitourinary/Vascular. In part A of this case, presenters will play the role of a 3D lab technologist; the case comes through with a clinical history of "rule out AAA." The task at hand: demonstrate the normal aorta, the techniques available to you to mitigate against the noise of the artifacts, and create a single summary image for the referring physician. Edit the volume to demonstrate the course of the renal arteries, then create a volume rendering, save it and close out.
Then Part B starts: the case is transferred to the reading room and you're the doc. Open the case and review it, then create a new volume rendering.
Only four minutes for this one -- EEEP! Here we go . . .
Dr. Mendel for Ziosoft, launching
