Journal ArticleDOI
Classification of teeth in cone-beam CT using deep convolutional neural network
Yuma Miki,Chisako Muramatsu,Tatsuro Hayashi,Xiangrong Zhou,Takeshi Hara,Akitoshi Katsumata,Hiroshi Fujita +6 more
TL;DR: This study investigated the application of a deep convolutional neural network (DCNN) for classifying tooth types on dental cone-beam computed tomography (CT) images and found the proposed method is advantageous in obtaining high classification accuracy without the need for precise tooth segmentation.
Journal ArticleDOI
3D-CT evaluation of facial asymmetry.
Akitoshi Katsumata,Masami Fujishita,Masahito Maeda,Yoshiko Ariji,Eiichiro Ariji,Robert P. Langlais +5 more
TL;DR: A 3D-CT imaging procedure for a 3-dimensional coordinate point evaluation system to assess and diagnose patients with facial asymmetry and is a practical method of evaluating the morphology of facial asymmetric.
Journal ArticleDOI
Effects of image artifacts on gray-value density in limited-volume cone-beam computerized tomography.
Akitoshi Katsumata,Akiko Hirukawa,Shinji Okumura,Munetaka Naitoh,Masami Fujishita,Eiichiro Ariji,Robert P. Langlais +6 more
TL;DR: The CBCT system using an FPD resulted in fewer artifacts than the CBCTsystem using an II in this particular study, and fewer artifacts were noted in images produced by the particular FPD CBCT used in this investigation.
Journal ArticleDOI
Image artifact in dental cone-beam CT
Akitoshi Katsumata,Akiko Hirukawa,Marcel E Noujeim,Shinji Okumura,Munetaka Naitoh,Masami Fujishita,Eiichiro Ariji,Robert P. Langlais +7 more
TL;DR: The probability that this artifact seen in limited-volume cone-beam CT imaging is caused by halation from the image intensifier (II) system is suggested.
Journal ArticleDOI
Relationship between density variability and imaging volume size in cone-beam computerized tomographic scanning of the maxillofacial region: an in vitro study
Akitoshi Katsumata,Akiko Hirukawa,Shinji Okumura,Munetaka Naitoh,Masami Fujishita,Eiichiro Ariji,Robert P. Langlais +6 more
TL;DR: Larger-volume CBCT scans may yield more consistent density values, as these volumes have the advantages of better image resolution and lower radiation doses.
