Abstract

fetched live from OpenAlex

EOS is an ultra low dose 2D/3D digital Xray system developed by Biospace Med and a team of France - Quebec engineers and clinicians. EOS is based on the Nobel Prize for Physics winner Georges Charpak’s detector technology that has been adapted for clinical Xray imaging. It allows for the simultaneous acquisition of two perpendicular digital images of patient in a weight-bearing standing position. Using a stereoradiographic reconstruction scheme based on a priori geometrical and statistical information about the 3D bones, dedicated software allows for the reconstruction and dynamic visualization of the 3D bone surface of the spine, the pelvis, the femur, the tibia, etc. Once the 3D models are obtained, it is then possible to obtain automatically over 100 true 3D angle and length measurements (cobb angles, vertebral rotations, wedging, kyphosis, lordosis, pelvic parameters, pangonogram data). Software also allows making any 3D desired measurements, using a set of simple interactive tools. A dosimetric study done in our laboratories has shown a 6 to 9 fold decrease in dose received by the patients compared to a normal full-length spinal exam. Furthermore, applications are being developed to evaluate the 3D deformity pre-operatively and post-operatively. A recent retrospective study identified several 3D parameters distinguishing patients with significant curve progression when compared to a group of patients with no progression of their initial scoliotic curve at maturity. These findings are currently evaluated in a prospective study.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
