Background: With the rapid development of computer technology, the application of digital technology to the display and processing of medical images has become a common concern. In recent years, oral digital imaging technology has received more and more attention.
Objective: This paper mainly aims at the ODIS-1 oral digital imaging system to analyze and study the image quality and image aims at the ODIS-1 oral digital imaging system to analyze and study the image quality and processing technology, of which X-ray imaging is indispensable.
Methods: In this paper, the ODIS-1 digital scanning technology is used to detect different types of dental tissues, and its application in diagnosing oral diseases is evaluated. This paper takes 320 inpatients as the research object and uses Kodak dental film to compare the image quality of different positions.
Results: It is found that there is no significant difference in image quality between the maxillary anterior teeth and mandibular anterior teeth and the maxillary posterior teeth and mandibular posterior teeth (P>0.05); the image quality of maxillary anterior teeth, mandibular anterior teeth, and maxillary posterior teeth and mandibular teeth are significantly different (P<0.05); among the various positions of the ODIS-1 oral digital imaging system, the image quality of the anterior teeth area is the best, while the image quality of the maxillary posterior teeth area is the worst.
Conclusion: However, the system has a variety of image post-processing functions, which can adjust the brightness and contrast of the image arbitrarily, select the area of interest in the image according to the detection requirements, and perform local amplification, edge enhancement, and other technologies to make the image achieve the best effect. In the case of poor image quality, the clarity of the image can be further improved through image post-processing and analysis.

Objectives: Although there has been rapid development in the field of three-dimensional morphological analyses of congenital heart disease, with the three-dimensional volume-rendered images providing visualization of the external vascular anatomy, the precise reproduction of "Swiss-cheese" ventricular septum is not well established. We created three-dimensional printed models and computer graphics based on multi-slice computed tomography of patients with complex multiple ventricular septal defects for surgical decision planning of this difficult cardiac defect.
Methods: Seven patients with complex multiple ventricular septal defects were evaluated preoperatively using three-dimensional printed models and computer graphics to plan therapeutic interventions.

Objective: To quantitatively and qualitatively compare directly two types of cisternography images for diagnosing trigeminal neuralgia (TN) using 3-T magnetic resonance imaging.
Methods: This prospective study recruited 64 patients with a clinical diagnosis or suspicion of TN. Patients were examined through the three-dimensional (3D) Constructive Interference in Steady State (CISS) and Sampling Perfection with Application-optimized Contrasts using different flip angle Evolutions (SPACE) sequences.

Introduction: We investigated the prevalence of new or persistent manifestations experienced by COVID-19 survivors at 3 or more months after their initial infection, collectively known as post-COVID-19 condition (PCC).
Methods: We searched four electronic databases and major grey literature resources for prospective studies, systematic reviews, authoritative reports and population surveys. A random-effects meta-analysis pooled the prevalence data of 22 symptoms and outcomes.

The relationship between sleep deprivation, obesity, and systemic inflammation is a critical area of investigation due to its significant impact on health. While it is established that poor sleep adversely affects obesity and metabolic syndromes, the specific mechanisms, particularly subclinical inflammation independent of obesity, remain unclear. This study investigates how sleep quality influences monocyte subclass distribution and its association with systemic inflammation across a spectrum of body mass index categories.
