SYSTEMS AND METHODS FOR PLANNING A PATIENT-SPECIFIC SPINAL CORRECTION
Systems and methods are provided to plan a spinal correction surgery. The method includes measuring parameters of a spine in a two-dimensional (2D) spinal image including a thoracic Cobb angle and a thoracic kyphosis (TK) and transforming the 2D image to a three-dimensional (3D), spinal image representation. The transforming includes performing segmentation of spine elements in the 2D image, and applying a formula based on the thoracic Cobb angle and the TK to the spine elements. The method includes identifying a TK goal having a post-operative TK value to selected spine elements, transforming a gap of the spine elements representative of a difference between the pre-operative TK in 3D spinal image representation and the TK goal to create a 3D post-operative spinal image representation, and determining a first rod design based on the 3D post-operative spinal image representation to achieve the post-operative TK value in the spine elements.

RADIOLOGICAL IMAGING METHOD AND RADIOLOGICAL APPARATUS WITH VERTICAL SCANNING OF 2 RADIATION SOURCES
A radiological apparatus including: a gantry encapsulated within a cover, a patient platform, and two radiation sources with imaging directions orthogonal to each other, sliding vertically to perform vertical scanning of a patient standing on the platform. The gantry cover top view is L shaped, each radiation source being located outside the gantry cover, inside the angular sector of the L, and is encapsulated within a cover sliding vertically with the radiation source it encapsulates. The radiological apparatus also includes: a first security device stopping the vertical scanning, when it detects a patient body part going outside a first predetermined area, to avoid collision with the vertically sliding radiation sources covers, and a second security device stopping the vertical scanning, when it detects an object or a person external to the radiological apparatus within a second predetermined area, to avoid collision with the vertically sliding radiation sources covers.
RADIOLOGICAL IMAGING METHOD
A radiological imaging method including: 2 radiation sources with imaging directions orthogonal to each other, performing vertical scanning of a standing patient along a vertical scanning direction, wherein the radiological method includes at least one operating mode in which: a frontal scout view is made so as to identify a specific bone(s) localization within the frontal scout view, both driving current intensity and voltage intensity modulations of the frontal radiation source, depending on patient thickness and on the identified specific bone(s) localization along the vertical scanning direction, are performed simultaneously, preferably synchronously, and automatically, so as to improve a compromise between: lowering the global radiation dose received by a patient during the vertical scanning, and increasing the local image contrasts of the identified specific bone(s) localization at different imaging positions along the vertical scanning direction, for the frontal image.
USE OF BONY LANDMARKS IN COMPUTERIZED ORTHOPEDIC SURGICAL PLANNING
A computing system generates, based on medical imaging data of bones of a joint of a patient, bony landmark data that characterizes relationships between two or more landmarks on one or more of the bones of the joint of the patient. Additionally, the computing system applies a classifier algorithm that has been trained using training data to select a class associated with the patient from among a plurality of classes. The classifier algorithm takes the bony landmark data of the patient as input.
