“…In addition, in the application study of the angiogram, the measurement of vascular position, bleeding area, blood flow, and other vascular-related information can be accurately evaluated with the help of an optical coherence tomography microscope. Compared with digital subtraction angiography, fluorescence angiography, and other development technologies, optical coherence tomography has the advantages of being fast, injection-free, high resolution, and so on [21] . It is believed that in the future, the optical coherence tomography microscopy application technology will continue to make breakthroughs, more widely used in all aspects of people's lives.…”

“…*msjeon@knu.ac.kr; phone +82-53-950-7846; photoacoustics.knu.ac.kr In this regard, Optical Coherence Tomography (OCT) emerges as a viable alternative [13,14]. As a non-invasive imaging modality, OCT provides meticulous tomographic data, enabling the early identification and monitoring of carious lesions [15][16][17][18]. Distinct from traditional imaging methods, OCT employs light waves, thus circumventing the risks associated with ionizing radiation.…”

Optical coherence tomography (OCT) is a non-invasive imaging method that provide high-resolution tomographic images. Attempts to incorporate OCT in dental practice have been ongoing, but the relatively bulky systems have limited their clinical utility. In this study, we utilized a microelectromechanical system (MEMS) to optimize the size of these OCT scanners to be similar to commercial intra-oral scanner (IOS) products. The optical axis of the internal scanner is designed in a Z shape to maximize the beam size reflected by the MEMS mirrors. To prove its usefulness in practical dentistry, we imaged the teeth in the oral cavity by position. Imaged teeth by position in the oral cavity demonstrated that the developed system can image deep into the oral cavity without difficulty. As a next step, we imaged teeth with cervical abrasion in three dimensions (3D) and high resolution. We classified the teeth into two types based on how the cervix was worn, and the degree of wear was quantitatively analyzed by performing A-scan profiling. This study demonstrates that the developed dental OCT system is effective in actual dental clinical practice and can be utilized for a variety of dental conditions.

“…Non-invasive subsurface data can be useful, but real-time scanning has not been possible [5,6]. Therefore, optical coherence tomography (OCT) may well be used intraoperatively for highresolution subsurface visualization to further improve the success rate [7,8]. A number of research groups have combined OCT with surgical microscopy for use in a variety of surgical situations in ophthalmology and otolaryngology [8][9][10][11].…”

Surgery of chronic otitis media (COM) is a sensitive procedure, where the success rate crucially depends on the surgeon and the significant depth visibility of the surgical microscope. Additionally, videotapes have been frequently adapted for surgical guidance at operation theaters. While these approaches provide great views and assistance during the surgery, it has proven more challenging to derive morphological and volumetric information on subsurface layers of COM. To address this issue, an intra-surgical spectral-domain optical coherence tomography (OCT) microscope system with an extended working distance of 280 mm was developed, which has augmented reality on the ocular eyepiece of a surgical microscope for more effective visualization of morphological structures during mastoidectomy or tympanoplasty. The cross-sectional OCT images guide surgeons to more easily identify targeted regions by displaying depth direction information in real-time during surgery. Three patients with COM participated in this study, and the pure-tone audiogram examinations were performed to evaluate pre and post-surgical conditions. The pure tone audiogram reveals that the operation was well performed based on the air-bone gap (ABG) reduction, and it can be confirmed that the hearing level was also improved. The success of the surgical procedure was confirmed through the intraoperative OCT images, and the post-examined audiogram results further confirmed the improvement of hearing. Hence, the integration of intra-surgical OCT and audiogram inspection methods revealed the potential merits of the proposed methodology.
