3333.2 - 3D Based Medical Application Working group

This standard focuses on the demands arising when scientific results in the field of 3D medical visualization are applied for the construction of a software system. It is targeted to aid the clinical work of medical professionals. This standard includes visualization techniques by the automated medical shape detection and reconstruction of three-dimensional (3D) models from two-dimensional medical images. Also it contains texturing of three-dimensional medical data for the intuitive visualization.

This standard includes medical 2D and 3D data management such as storage, compression for transfer, regulation for wired or wireless transfer and search engine development for data retrieval.

This standard discusses the simulation of the movement of joints and subsequent changes of skin, muscle, and neighboring structures. It defines joint range of motion, movement, and structure of skeleton for rigging work. Additionally, it reviews simulation devices such as haptic devices or software and hardware based on reality augmented equipment.

This standard defines the Bio-CAD format for three-dimensional (3D) Printing based on Sectional Scan image data containing surface and volumetric information. Standardization is related to medical 3D printing services, including anatomic, pathologic models and medical instrument printing based on two-dimensional images, three-dimensional medical data and other medical data.

This standard defines a data file format standard that increases the precision of 3D printing model output of hard tissues in medical images. Standardization involves the use of medical scanning devices to acquire physical data models with density and size characteristics and to develop comparative analysis data.

This standard defines patient-specific guide block design and 3D modeling technology standards for high-precision 3D printing to increase patient satisfaction with orthopedic implant surgeons.

This standard defines the optimal design elements for medical 3D printing based on the analysis of the technical elements of artificial joint outputs required by the orthopedic surgeon, the patient's affected three-dimensional model data, and artificial joint templates. Standardization includes medical three-dimensional models such as the location, orientation and shape of orthopedic osteotomy, and patient-specific artificial joint model data for 3D printing.

This document specifies the in vivo examination required for the biological assessment of three-dimensional (3D) bio-printed polymeric scaffolds intended for use in bone regeneration. 3D bio-printed scaffolds are gaining increased attention and animal experiments are fundamental in assessing their performance prior to potential clinical use. In vivo assessment will include the following features. Animal model include rat or rabbit. Bone defect can be created on the skull, femur or pelvis. The defect size is minimum 5mm3 in volume. Assessment include histopathological, radiological and mechanical assessment.
