Computer-aided modelling of three-dimensional maxillofacial tissues through multi-modal imaging.

Recent developments in digital imaging techniques have allowed a wide spread of three-dimensional methodologies based on capturing anatomical tissues by different approaches, such as cone-beam computed tomography, three-dimensional photography and surface scanning. In oral rehabilitation, an objective method to predict surgical and orthodontic outcomes should be based on anatomical data belonging to soft facial tissue, facial skeleton and dentition (maxillofacial triad). However, none of the available imaging techniques can accurately capture the complete triad. This article presents a multi-m…

Novel observations and potential applications using digital infrared iris imaging.

Digital infrared iris photography using a modified digital camera system was performed on approximately 300 subjects seen during routine clinical care and research at one facility. Because this image database offered an opportunity to gain new insight into the potential utility of infrared iris imaging, it was surveyed for unique image patterns. Then, a selection of photographs was compiled that would illustrate the spectrum of this imaging experience. Potentially informative image patterns were observed in subjects with cataracts, diabetic retinopathy, Posner-Schlossman syndrome, iridociliary…

A histologic study of lens regeneration in aphakic rabbits.

Lens regeneration occurs in New Zealand albino rabbits after endocapsular lens extraction, which leaves the anterior and posterior lens capsules relatively intact. Slit-lamp photography, histologic studies, and lens protein analysis confirmed the differentiation of lens fibers. In the current study, we performed a sequential analysis of the regenerating rabbit lens. After endocapsular phacoemulsification and irrigation/aspiration of the lens, rabbits were sacrificed at different time points for histologic evaluation. Similarities with embryologic development of the lens were evident, although …

MooneyMaker: A Python package to create ambiguous two-tone images.

Mooney images are high-contrast, two-tone visual stimuli, created by thresholding photographic images. They allow researchers to separate image content from image understanding, making them valuable for studying visual perception. An ideal Mooney image for this purpose achieves a specific balance: it initially appears unrecognizable but becomes fully interpretable to the observer after seeing the original template. Researchers traditionally created these stimuli manually using subjective criteria, which is labor intensive and can introduce inconsistencies across studies. Automated generation t

A Review on Image Processing and Fractal Analysis in Oral Potentially Malignant Disorders.

AIM: The clinical evaluation of patients with oral potentially malignant disorders is primarily based on physical examination and observable clinical features. Clinical photographs play a key role in patient monitoring and help identify signs that may indicate malignant transformation. These images can be accessed by artificial intelligence techniques and fractal analysis, and image processing and segmentation are crucial for these tasks. This review discusses image processing techniques applied to clinical photographs of oral potentially malignant disorders, with emphasis on fractal analysis.

Five electronic databases (SCOPUS, Web of Science, PubMED, TRID and PROQuest) were used to identify relevant s

Measuring the Unmeasurable: Challenges Associated With Objective Assessment of Aesthetic Outcomes Following Breast Reconstruction.

Current approaches for assessing breast reconstruction outcomes are based on subjective and objective criteria. Subjective analysis is often performed by assessing patient-reported outcomes, of which the BREAST-Q is most common. Objective analysis is often performed by photographic analysis of various breast parameters based on a grading scale that can be numeric or qualitative (poor-excellent). Both are useful, but both are also limited in that the subjective and objective assessments may not correlate. This paper explores the current role, strengths, and limitations of these assessment tools

A Comparative Assessment of Surgeon Appraisal of Presurgical Infant Orthopedics Outcomes Using PLANA and NAM.

Presurgical lip, alveolus, and nose approximation (PLANA) is a novel form of presurgical infant orthopedics (PSIO) involving a prefabricated silicone intranasal device combined with hydrocolloid adhesive lip taping. Early studies have demonstrated favorable nasolabial morphologic outcomes using PLANA and a reduction in the burden of care on infants and their caregivers relative to nasoalveolar molding (NAM). However, the efficacy of PLANA in reducing cleft severity to facilitate surgical repair has not been comprehensively assessed from the perspective of the cleft surgeon. This study, therefo

Iconographic validation of the Bristol scale in patient with neurological diseases.

INTRODUCTION: The Bristol Stool Scale, published by Heaton et al. in 1988 in a population of patients suffering from irritable bowel syndrome, is a self-assessment tool to estimate stool appearance and therefore the transit time. It is a widely used scale recommended in the 2016 ROME IV criteria to diagnose chronic constipation. Although initially validated in a large population of patients with gastrointestinal disorders, its specific evaluation in a population suffering from neurological diseases has never been validated. METHODS: Subjects were asked to orally categorize nine color photos o
