You necessitate for it and here it is : undivided videos of the CTX Imaging systemwe show you yesterday . Here you may see a pig eat in slow movement , start up with the X - shaft pic alone and then superimposing the 3D skull .

CTX Imaging is a unique method acting that uses computed - imaging with high-pitched - f number cinefluoroscopic telecasting ( 1,000fps ) and X - rays to make extremely accurate seizure of systema skeletale in very dissipated motion . We talked with Dr. Elizabeth Brainerd , from the Department of Ecology and Evolutionary Biology at Brown University , who explains this open task after the start .

Gizmodo : What are we bet at there ?
Dr. Brainerd : This is a marker - establish CTX of a grunter feed in sluggish motion , at 1/4 real hurrying . The squealer collect pig chow from the ground and then chews for several cycles before collect more food . The ten - ray movie is show first , and then the 3D skull and jaw models from CT are superimposed to show the accurate alinement of the bones over time .
Gizmodo : What is the method to reach this variety of imaging ?
Dr. Brainerd : Small metal beads were surgically implanted into the upper and lower jaw and teeth . A 3D model from CT scanning was made of the skull and jaw . Biplanar , high - speed cinefluoroscopic video of eating was collect and the X - beam of light picture was used to align the markers in the CT theoretical account to create an exact ( ±1 mm ) reconstruction of osseous tissue berth over sentence .
Gizmodo : How long does it take get the unconscious process complete , from the tomography scan to net animation ?
Dr. Brainerd : Animal breeding , surgery to implant the metal spheres into the osseous tissue and recovery together take 1 - 2 weeks . Then we can collect and process the CT scan data in one Clarence Day and the ecstasy - ray movie data in one day .
For one movement sequence it takes about 3 - 4 hours to evoke the 3D coordinates of the metallic element spheres from the two video views , and then another 3 or so hr to combine the front coordinates with the 3D model from the CT scan using the animation program Maya . So three days for data point collection and processing . We are just getting bulge out with our software developing , so we expect that some of these steps will be faster and more automated in the time to come .
Gizmodo : Are you contrive to do this in real time in the future ? Is that even potential ?
Dr. Brainerd : existent meter could , I recollect , be potential with radiopaque alloy spheres surgically implant in the bones — so for experimental animals only ( not humans ) .
We presently have no plans to develop real - time CTX imaging because we are create this technology for scientific inquiry , and we do not see a current inquiry software for substantial - fourth dimension imaging . There could be some entertainment value in real time . It sure would be fun to see the bones inside an animal move in veridical sentence — just like have Xx - ray vision .

Gizmodo : Are there any potential commercial applications ?
Dr. Brainerd : There may be next aesculapian software , peculiarly in orthopaedics , maxillofacial surgery and possibly orthodontics . Seeing bones ( and teeth ) in action before and after treatment may aid design procedures to match patients ’ individual needs and to evaluate the efficaciousness of the handling . At Brown we have three orthopedic bioengineering mental faculty on our CTX inquiry squad , and research groups at Henry Ford Hospital in Detroit and University of Pittsburgh have made great strides toward developing a marker - less system that can be used for human subject area . We are also work toward a markerless CTX system at Brown , but at the moment we have only implemented a scheme that demand the surgical implantation of small ( 1 mm or less ) metal spheres into the bone .
Seeabstract of a talk from the HFH and Pitt groups given by Scott Tashman at the 2006 American Society of Biomechanics meeting :
Gizmodo : Are you planning on licensing this engineering to other scientific foundation or is it an clear labor , uncommitted for everyone ?
Dr. Brainerd : receptive project . We are currently working on a internet site that will have some software downloads and selective information on where to buy and how to build the necessary computer hardware .
Gizmodo : Amazing , and who is paying for all this cool geartrain ?
Dr. Brainerd : This CTX development undertaking at Brown is fund by the W.M. Keck Foundation and the National Science Foundation .
Thanks to Dr. Brainerd for her clip and all the videos .
