WR-3D is Angell Technology's weight-bearing radiographic 3D imaging system for spine, lower limb, hip, knee, and ankle assessment, combining volumetric reconstruction, AI measurement, and 2D fluoroscopy support.
Weight-Bearing Radiographic 3D system
WR-3D utilizes volumetric imaging technology to achieve full three-dimensional reconstruction of the scanned area in a weight-bearing position. It delivers comprehensive views across coronal, axial, and sagittal planes, and supports reconstruction of MIP, MPR and VR.
WR-3D supports comprehensive 3D scanning of the full spine, full lower limbs, and specific joint regions including the hip, knee, and ankle.
WR-3D provides AI-assisted measurements for scoliosis and knee osteoarthritis assessment, supporting orthopedic planning and follow-up review.
WR-3D combines weight-bearing 3D imaging with 2D radiography, stitching, fluoroscopy and contrast study workflows in one platform.
WR-3D reconstructs weight-bearing 3D datasets into coronal, axial and sagittal views, with MIP, MPR and VR modes for reviewing the scanned anatomy.
WR-3D supports standing 3D review of the full spine, full lower limbs and key joint regions including the hip, knee and ankle.
WR-3D provides AI-assisted measurements for scoliosis and knee osteoarthritis assessment, supporting orthopedic planning and follow-up review.
WR-3D combines weight-bearing 3D imaging with 2D radiography, stitching, fluoroscopy and contrast study workflows in one platform.
3D Imaging Demo
This video demonstrates the WR-3D 3D imaging display, showing how reconstructed volumetric views can support review of skeletal anatomy beyond a single flat projection.
Standing cone-beam acquisition
WR-3D uses a fixed X-ray tube and flat-panel detector while the patient stands on a motorized platform between them. The workflow is built for weight-bearing orthopedic assessment, where posture control during rotation is part of image quality, not a separate setup detail.
The tube-detector relationship stays fixed while the patient platform rotates through the acquisition path.
Patient instruction and stance confirmation are part of acquisition setup because weight shift can affect standing 3D reconstruction.
Controlled platform rotation keeps posture consistency within the scan workflow instead of treating rotation as only a timing metric.
Full-spine 3D stitching
For long anatomical regions, WR-3D acquires successive standing scan segments along the vertical axis. The reconstructed segments are combined into long-field views for spine or lower-limb review while the patient remains in a weight-bearing position.
Each segment is captured with the patient upright, avoiding a supine-to-standing posture transfer.
Successive scan ranges are used when the clinical question requires extended spine or lower-limb coverage.
Stitched views are generated within the selected reconstruction protocol, keeping extended review tied to the scan setup used for that examination.
Orthopedic assessment in WB posture
WR-3D is positioned for orthopedic scenarios where standing posture changes anatomical relationships, including scoliosis assessment, lower-limb alignment, knee joint review and postoperative follow-up. Reconstructed slices and 3D views help separate structures that overlap in a single projection.
