Radiation Exposure Evaluation Depending on Radiation Workers' Locations during Dental Radiography
Autor: Ji Young Kim, Cheon-Soo Jeong
Publikováno v: Journal of the Korean Society of Radiology. 9:433-438
To evaluate the radiation exposure level based on radiation workers’ locations in dental radiography, the radiation dose rate in the radiographic room, lead glass, and operation system was measured. To that end, various devices were used, such as a

Tooth Distortion as a Function of Arch Form in Cone Beam Computed Tomography
Autor: Kyu-Ji Joo, Woon-Kwan Chung, Yoon-Jeong Seo, Jae-Woo Shin, Kyung-Rae Dong, Cheon-Soo Jeong
Publikováno v: Spectroscopy Letters. 48:84-89
The cone beam computed tomography enables conducting measurement of length and area in the space where it is impossible to conduct such measurement compared to panorama. The cone beam computed tomography also enables making three-dimensional diagnosi

A study on the effect of using a flattening filter in a medical linear accelerator on the dose distribution
Autor: Kyung-Rae Dong, Woon-Kwan Chung, Yoon-Jeong Seo, Cheon-Soo Jeong, Chang-Seon Lim, Young-Jae Kim
Publikováno v: Journal of the Korean Physical Society. 64:917-922
This study compared the dependence of the tissue maximum ratio (TMR) and the beam profile on the use of a flattening filter when a linear accelerator is used for radiation exposure of a small field size. To examine change according to the field size,

Analysis of Image Distortion by Mandibular Arch Form in Cone Beam CT and Panoramic Image
Autor: Cheon-Soo Jeong, Gee-Heun Lee
Publikováno v: Journal of the Korean Society of Radiology. 7:301-305
This thesis intends to analyze tooth distortion by mandibular arch form by reproducing existing panorama image and reconstructed panorama image of Cone Beam CT data with the three-dimensional computer program. The diameter of tooth measured in Cone B

Comparison of Dose Depending on the Position when Shooting Panorama and CBCT
Autor: Cheon-Soo Jeong, Chong-Yeal Kim
Publikováno v: Journal of the Korean Society of Radiology. 7:175-179
To find out the appropriate defensive measures for protectors and radiation workers in rotating radiation generating devices such as CBCT and panorama, irradiation dose depending on the position was compared and analyzed. The devices such as panorama

Study on accuracy of panorama and CBCT through length measurement of wisdom teeth
Autor: Chong-Yeal Kim, Cheon-Soo Jeong
Publikováno v: Journal of the Korean Society of Radiology. 7:131-136
Panorama of dental radiation generators can observe the wide anatomical structures of oral and maxillofacial areas but there can be distortion of lengths, angles, or shapes. CBCT can diagnose 3D images and get the ones whose errors by superposition a

Publikováno v: Journal of the Korean Society of Radiology. 5:369-375
In dental radiography, panoramic views cause distortion and thus may bring about inaccurate results in the process of quantitative analysis. In this connection, there has recently been an increasing use of cone beam computed tomography (CBCT) that is

The Study for Radio Protection According to a Possible Danger of Exposure During dental X-ray Examination
Autor: Hong-Ryang Jung, Dong-Hee Hong, Cheon-Soo Jeong, Seung-Chul Kim, Cheong-Hwan Lim, In-Gyu You
Publikováno v: Journal of the Korean Society of Radiology. 5:237-244
Generally, X-ray examinations for dentistry use low energy radiation. It explains that the radiations are mainly absorbed to a human body because of the weak perm- eability. We made up some counterplans for decrease in radiation exposure, when guardi
