Generation of maxillofacial imaging volume with motion

Abstract

Various aspects of systems, methods, and related aspects to generate a maxillofacial imaging volume with motion, from a three-dimensional (3D) extra-oral x-ray system, are described. One example technique includes: obtaining imaging data of a patient, captured during movement of an upper jaw and the lower jaw of the patient; establishing a motion model that defines an expected movement of the upper jaw relative to the lower jaw; segmenting the imaging data into at least an upper jaw segment corresponding to the upper jaw and a lower jaw segment corresponding to the lower jaw, based on the expected movement defined by the motion model; performing motion artifact correction separately on the upper jaw segment and the lower jaw segment; and outputting an imaging volume that includes an artifact-corrected representation of the upper jaw segment and an artifact-corrected representation of the lower jaw segment. 20 26 20 18 88 12 M ar 2 02 6 1 2 M a r 2 0 2 6 2 0 2 6 2 0 1 8 8 8 1 2 M a r 2 0 2 6 2 0 2 6 2 0 1 8 8 8 F IG . 1 1 / 8 11 0 11 0 C O M P U T IN G S Y S T E M 12 4 12 4 11 2 11 2 14 2 14 2 14 4 14 4 O U T P U T D E V IC E IN P U T D E V IC E C B C T IM A G E D A T A P R O C E S S IN G G R A P H IC A L U S E R IN T E R F A C E 10 0 10 0 M O T IO N A R T IF A C T C O R R E C T IO N P R O C E S S IN G 10 4 10 3 10 1 10 5 10 6 11 6 11 6 11 4 11 4 12 6 12 6 12 2 12 2 M E M O R Y IM A G E S E G M E N T A T IO N P R O C E S S IN G 14 0 14 0 M O T IO N D IS P LA Y P R O C E S S IN G P R O C E S S IN G C IR C U IT R Y S T O R A G E D E V IC E 12 8 12 8 1 0 0 1 1 0 1 0 1C O M P U T I N G S Y S T E M C B C T1 2 2 1 1 2 I M A G E D A T A P R O C E S S I N G P R O C E S S I N G C I R C U I T R Y M O T I O N A R T I F A C T 1 0 41 0 3 C O R R E C T I O N 1 1 4 P R O C E S S I N G 1 0 6 M E M O R Y I M A G E 1 2 6 S E G M E N T A T I O N 1 1 6 P R O C E S S I N G 1 / 8 0 0 :0 0S T O R A G E 1 2 8 D E V I C E M O T I O N D I S P L A Y P R O C E S S I N G 1 0 5 G R A P H I C A L 1 4 0 U S E R I N T E R F A C E 1 4 2 1 4 4 O U T P U T D E V I C E I N P U T D E V I C E F I G . 1 20 26 20 18 88 12 M ar 2 02 6 2 0 2 6 2 0 1 8 8 8 1 2 M a r 2 0 2 6 1 0 0 1 1 0 1 0 1C O M P U T I N G S Y S T E M C B C T1 2 2 1 1 2 I M A G E D A T A P R O C E S S I N G P R O C E S S I N G C I R C U I T R Y M O T I O N A R T I F A C T 1 0 41 0 3 C O R R E C T I O N 1 1 4 P R O C E S S I N G 1 0 6 M E M O R Y I M A G E 1 2 6 S E G M E N T A T I O N 1 1 6 P R O C E S S I N G 1 / 8 0 0 :0 0S T O R A G E 1 2 8 D E V I C E M O T I O N D I S P L A Y P R O C E S S I N G 1 0 5 G R A P H I C A L 1 4 0 U S E R I N T E R F A C E 1 4 2 1 4 4 O U T P U T D E V I C E I N P U T D E V I C E F I G . 1 2 0 2 6 2 0 1 8 8 8 1 2 M a r 2 0 2 6 1 0 1 1 0 41 0 3 1 0 6 1 / 8 0 0 :0 0 1 0 5 F I G . 1
