Whether some people like it or not, 3D imaging has made it a volume-based world. Division remains, however, between those who wouldnt want to image any other way and those who wish 3D would go away. The latter group would like to continue its status quo imaging and not deal with 3Ds formidable learning curve, but to deny 3Ds importance is unrealistic. Innovations ranging from improved processing to better training are filling 3Ds breach. And in the future, radiologists and surgeons will find it harder to imagine imaging without 3D.
From CT and MR to ultrasound and high-speed C-arms, 3D is providing better information for patients and assisting physicians and surgeons in planning treatment and surgery. But as bright as 3Ds future may be, present issues need to be addressed for the technology to reach its full potential and to bring 3D imaging onto the radar screens of the remaining skeptics and resistors. Education and training remain key elements in ensuring 3Ds continued growth and acceptance.
Elliot Fishman, director of diagnostic radiology and body CT at The Johns Hopkins Hospital (Baltimore, Md.) and long-time proponent of volume visualization, typically asks attendees at 3D work sessions he conducts how many users feel they are well trained on their workstations. Invariably, one person raises his hand, Fishman says. People are not well-trained on how to use their workstation, and the typical thing is if you are not well trained, you do not use it. And thats where the changes in workflow [come in].
Radiologists, Fishman says, are very enthusiastic about the 3D process as are techs who often are still involved in preparing more complex images for viewing and manipulation by radiologists. Their ability to do it may not exactly be there because they dont have the capabilities, but I think that people now recognize as companies do that working to figure out ways [to train and educate] is not a simple answer, Fishman says. People dont have the time. Youve heard all the stories, but the reality is those stories dont work very well. You have to get down to business.
It speaks volumes
Initially, 3D was a separate process that was performed on a separate workstation for select applications. Now, however, 3D functionality is beginning to be built into the scanner at the front of the process. Siemens Medical Solutions (Malvern, Pa.) has InSpace built into the computer, Fishman says. Its on their workstations also, but you dont have to be far from the scanner to do it. You can do it in real time. With demands now 24/7 for this type of processing, it needs to be on the scanner, available immediately. It cant be something that becomes available three days later. Thats the big thing. Its changing what you need to do.
