ASSESSMENT OF PROBABILITY OF BONE FRACTURE
20230238136 · 2023-07-27 ·

A patient-specific assessment of fracture probability for the femur proximal end is provided. 3D locations of the femur head center, a point on the femoral shaft center, and the femoral intercondylar notch are determined from a clinical image. A frontal plane, a perpendicular thereunto and a bone shaft axis are determined from the 3D locations. An FEA coordinate system is defined from the frontal plane, the perpendicular and the axis. Two FEA analyses are performed, one for neck fracture and one for pertrochanteric fracture, with the same displacement constraints and the same load magnitude but different load angles. The femur proximal end is divided into four anatomically-based regions. For each region and each load, maximum tensile and compressive principal strains are determined and, based on the body weight and the principal strains, a likelihood of fracture is obtained. The minimum of these 8 likelihoods gives the probability of fracture.

REAL-TIME MONITORED COMPUTED TOMOGRAPHY (CT) RECONSTRUCTION FOR REDUCING RADIATION DOSE

Real-time monitored computed tomography (CT) reconstruction for reducing a radiation does. During helical CT scanning of a target object, projections may be acquired in either a full mode which subjects the target object to a full radiation dose, or a reduced mode which subjects the target object to a reduced radiation dose (e.g., by reducing the number of projections acquired, reducing the exposure time, etc.). After a sector is acquired in the full mode, a slice of the target object that is influenced by that sector is identified, and a CT image of that slice is reconstructed using projections that have been previously acquired for that slice. When a stopping rule is satisfied based on this partial reconstruction, the full mode is switched to the reduced mode, and at least one subsequent sector is acquired in the reduced mode.

Radiographic imaging identifies a subject anatomy for radiographic image content and automatically identifies a subject’s position from one or more sensor signals. The imaging apparatus issues re-positioning guidance signals for re-positioning the patient. Signals are generated to set an imaging exposure technique and component positions according to data associated with the subject anatomy. A radiographic image of the subject is acquired according to the component and technique signals by automatically energizing the x-ray source. The acquired radiographic image is analyzed using trained logic to determine clinical diagnostic suitability of the image and to identify one or more abnormalities in the subject anatomy.
