    The portable document format (PDF) is a globally recognized standard file format of Word documents. The PDF supports the embedding of three-dimensional objects. This three-dimensional PDF can contribute to new ways of presenting and disseminating medical information in future medical journals.

  • Development of an educational three-dimensional anatomical structure replication tool and its application to medial open-wedge high tibial osteotomy

    Background: With the standardization of surgical techniques and continuous development of plate fixators, medial open-wedge high tibial osteotomy (OWHTO) has become an option for the treatment of medial knee osteoarthritis. However, it is also associated with several complications. To reduce the risk of these complications, it is essential for surgeons to accurately understand the three-dimensional (3D) anatomical structures, including the surroundings of the surgical field. Gross dissection using a cadaver provides a large surgical field and is the best learning method for studying anatomical structures in three dimensions; however, it is not available at all medical institutions. Methods: One female cadaveric knee, fixed using the Thiel method, was used in this study, and OWHTO was performed. A series of photographs was taken from approximately 60 different angles at each stage of the autopsy for digital photogrammetry to ensure that there was at least a 60% overlap between photographs. Results: Each 3D object was created to be faithful to the original specimen and displayed on an augmented reality headset. It was created to capture the subtle nuances of irregular shapes and structures, highlighting the unique ability of photogrammetry to capture pathology. This method allows surgeons to visualize the location of neurovascular injuries in the intraoperative field of view. Conclusions: Using a technique that applies digital photogrammetry to create 3D objects from handheld photographs, this reports for the first time an educational tool that can reproduce the anatomy related to high tibial osteotomy in three dimensions.

  • A technique for decreasing reflection during cadaveric photography

    Clinical Anatomy （Clinical Anatomy)  36 （ 6 ） 946 - 950 2023.09

    　View Summary

    To create anatomical educational materials that can be viewed in three dimensions using stereo photographs and photogrammetry, multiple photographs must be taken from different directions. In this process, shadows and reflections from different positions in each photograph are undesirable for creating three-dimensional (3D) anatomy educational materials. Although a ring flash eliminates shadows, allowing light to enter from all directions, reflections cannot be eliminated. In particular, Thiel-embalmed cadavers, which are widely used in clinical anatomy, are highly wet and exhibit strong specular highlights. In this study, a straight polarization filter was attached to a handheld camera lens and ring flash, and shooting was performed using cross-polarization photography. Consequently, even in Thiel-embalmed cadavers, the details lost due to the effects of reflections and shadows can be recovered, and good results can be obtained when taking stereo photos or creating a 3D model using photogrammetry.

  • A Novel Dissection Method of the Internal Mammary (Thoracic) Artery: Anastomotic Vessel of the DIEP Flap

    Summary: Deep inferior epigastric perforator flaps are commonly used for breast reconstruction using autologous tissue. For such free flaps, the internal mammary artery provides stable blood flow as the recipient for anastomosis. We report a novel dissection method of the internal mammary artery. First, the perichondrium and costal cartilage of the sternocostal joint are dissected with electrocautery. Then, the incision on the perichondrium is extended along the cephalic and caudal ends. Next, this C-shaped superficial layer of perichondrium is elevated from the cartilage. The cartilage is incompletely fractured with electrocautery, with the deep layer of perichondrium intact. Then, the cartilage is completely fractured by leverage and removed. The remaining deep layer of perichondrium is incised at the costochondral junction and shifted aside, revealing the internal mammary artery. The preserved perichondrium creates a rabbet joint to protect the anastomosed artery. This method not only enables a more reliable, safer dissection of the internal mammary artery, but also allows reusage of the perichondrium as underlayment in the setting of anastomosis, and coverage for the incised rib edge, protecting the anastomosed vessels.

  • Multi-View Surgical Camera Calibration with None-Feature-Rich Video Frames: Toward 3D Surgery Playback

    　View Summary

    Mounting multi-view cameras within a surgical light is a practical choice since somecameras are expected to observe surgery with few occlusions. Such multi-view videos must bereassembled for easy reference. A typical way is to reconstruct the surgery in 3D. However, thegeometrical relationship among cameras is changed because each camera independently moves everytime the lighting is reconfigured (i.e., every time surgeons touch the surgical light). Moreover, featurematching between surgical images is potentially challenging because of missing rich features. Toaddress the challenge, we propose a feature-matching strategy that enables robust calibration ofthe multi-view camera system by collecting a set of a small number of matches over time whilethe cameras stay stationary. Our approach would enable conversion from multi-view videos to a3D video. However, surgical videos are long and, thus, the cost of the conversion rapidly grows.Therefore, we implement a video player where only selected frames are converted to minimizetime and data until playbacks. We demonstrate that sufficient calibration quality with real surgicalvideos can lead to a promising 3D mesh and a recently emerged 3D multi-layer representation. Wereviewed comments from surgeons to discuss the differences between those 3D representations on anautostereoscopic display with respect to medical usage.
