COMPUTER-IMPLEMENTED METHOD FOR ASCERTAINING AN ITEM OF TORSION INFORMATION OF A BONE, X-RAY FACILITY, COMPUTER PROGRAM AND ELECTRONICALLY READABLE DATA CARRIER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240050045 titled 'COMPUTER-IMPLEMENTED METHOD FOR ASCERTAINING AN ITEM OF TORSION INFORMATION OF A BONE, X-RAY FACILITY, COMPUTER PROGRAM AND ELECTRONICALLY READABLE DATA CARRIER

Simplified Explanation

The patent application describes systems and methods for determining torsion information of a bone in a patient using an x-ray facility with adjustable projection geometry. The method involves recording a first x-ray image of the end region of the bone in a first projection geometry, where the torsion direction lies in a first computing plane. A second x-ray image is then recorded in a second projection geometry with a different direction of projection, forming a second computing plane. The three-dimensional course of the reference direction and the torsion direction is determined from the computing planes and the roll angle, which represents the rotation of the torsion direction about the reference direction. The torsion information is ascertained from the roll angle.

• The patent application describes a method for determining torsion information of a bone using adjustable projection geometry in an x-ray facility.
• The method involves recording two x-ray images of the bone in different projection geometries and determining the three-dimensional course of the reference direction and the torsion direction.
• The torsion information is then ascertained from the roll angle, which represents the rotation of the torsion direction about the reference direction.

Potential applications of this technology:

• Medical imaging: This technology can be used in medical imaging to accurately determine torsion information of bones, which can be useful in diagnosing and monitoring conditions such as bone deformities, fractures, and joint disorders.
• Orthopedic surgery: Surgeons can use this technology to plan and guide orthopedic surgeries, especially those involving bones with complex torsion patterns.
• Rehabilitation and physical therapy: Torsion information can be valuable in designing personalized rehabilitation and physical therapy programs for patients recovering from bone injuries or surgeries.

Problems solved by this technology:

• Accurate torsion measurement: The adjustable projection geometry and the use of computing planes allow for precise determination of torsion information, overcoming limitations of traditional imaging techniques.
• Non-invasive assessment: This technology provides a non-invasive method for assessing torsion information of bones, reducing the need for invasive procedures such as exploratory surgeries.
• Improved treatment planning: The accurate measurement of torsion information can aid in the planning and execution of orthopedic surgeries, leading to better outcomes for patients.

Benefits of this technology:

• Enhanced diagnostic capabilities: The ability to accurately determine torsion information can improve the diagnosis and understanding of bone conditions, leading to more targeted and effective treatment plans.
• Minimally invasive approach: By using x-ray imaging, this technology offers a non-invasive alternative to invasive procedures, reducing patient discomfort and recovery time.
• Improved surgical outcomes: Surgeons can use the torsion information obtained through this technology to plan and execute surgeries with greater precision, potentially improving surgical outcomes and patient recovery.

Original Abstract Submitted

systems and methods for ascertaining an item of torsion information of a bone of a patient, wherein an x-ray facility with adjustable projection geometry of a recording arrangement described by projection parameters is used. a first x-ray image is recorded of an end region of the bone in a first projection geometry in which a torsion direction defined relative to at least one torsion landmark and used for ascertaining a roll angle lies in a first computing plane, which is formed by the focal point of the x-ray source and a reference direction which may be determined in the first x-ray image by at least one reference landmark. a second x-ray image is recorded of the end region of the bone in a second projection geometry with a direction of projection deviating from the direction of projection of the first projection geometry, and forming a second computing plane from the reference direction which may be determined in the second x-ray image likewise by the at least one reference landmark, and the focal point. the three-dimensional course of the reference direction and the torsion direction is determined from the computing planes and the roll angle as the rotation of the torsion direction about the reference direction with respect to a comparison specification. the item of torsion information is ascertained from the roll angle.
