Although many 3D medical imaging visualization methods exist, 3D volume slicing remains the most commonly used technique for visualizing medical data from modalities such as CT, MRI and PET. We propose to extend the possibilities of oblique slicing to developable curved surfaces that can be flattened and displayed in 2D without deformation. Such surfaces can be used to follow curved anatomical ...

Although many three-dimensional (3D) medical imaging visualization methods exist, 3D volume slicing remains the most commonly used technique for visualizing medical data from modalities such as CT, MRI, and PET. We propose to extend the possibilities of oblique slicing to developable curved surfaces that can be flattened and displayed in two dimensions without deformation. Such surfaces can be ...

BACKGROUND The ideal male jaw angle has not been established. With the advent of additive manufacturing, precise customized shaping is a reality. This study aimed to define the ideal masculine mandibular angle as an aid for 3-dimensional (3D) design. METHODS An Internet survey was conducted using black/white photographs of celebrities and non-celebrities. Preferences regarding gonial angle (p...

We propose a new service for building user-defined 3D anatomic structures on the Web. The Web server is connected to a data base storing more than 1000 3D anatomic models reconstructed from the Visible Human. Users may combine existing models as well as planar oblique slices in order to create their own structured anatomic scenes. Furthermore, they may record sequences of scene construction and...

This paper describes an innovative method for correctly estimating the effective field size of tangential-breast fields. The method uses an "equivalent triangle" to verify intact breast tangential field monitor-unit settings calculated by a 3D planning system to within 2%. The effects on verification calculations of loss of full scatter due to beam oblique incidence, proximity to field boundari...

[Purpose] The purpose of this study was to investigate the activation of the vastus medialis oblique muscle (VMO) and vastus lateralis muscle (VL) during squat exercise with various hip adduction loads using a pressure-biofeedback unit, and to suggest the most effective exercise method. [Subjects] We recruited 15 healthy adult females with no pain in the knee joint and no other orthopedic probl...

This paper proposes a simple but efficient technique to control 3D overhead crane. Load must track a desired path and not sway more than a reasonable range.The proposed method uses PID control for trolley to track the desired path and fuzzy control compensation to eliminate the load swing. Only the projection of swing angle is applied to design the fuzzy controller. No plant information of cran...

In this paper, a method for measuring 3D cognitive load is proposed. For that, 8-channel EEG data when watching 2D and 3D displays are 2dimensionally reduced using principal component analysis then the reduced features are visualized and compared. Consequently, we confirmed that the difference between two feature distributions of watching 2D and 3D at early stage was significant then the differ...

Background and Aim: Oral bacteria can proliferate in the implant-abutment interface (IAI) and cause inflammation in the peri-implant tissues and adjacent bone. This study aimed to assess the effect of zirconia and titanium abutments on the microleakage of the IAI under oblique cyclic loading conditions. Materials and Methods: In this in-vitro study, 12 implant-abutment assemblies with zirconia...
