Background: The aetiology of colorectal cancer has strong dietary links, and there may be an association between coffee and colorectal cancer risk. Objective: To study the effects of filtered (low levels of kahweol/cafestol) and unfiltered (high levels of kahweol/cafestol) coffee on tumour formation in multiple intestinal neoplasia (Apc ) mice. Design: Apc mice (n 11 per group) were fed for 9 w...

Panoramic photo stitching is the process of combining multiple photographic images with overlapping fields of view to produce a panorama. The process to generate a panoramic view can be divided into three main components image acquisition, image registration, and blending. In this paper, a robust algorithm called Scale Invariant Feature Transform (SIFT) used to extract the features from the ima...

Objectives: The objective of this case report was to determine radioopacities of the cervical region on panoramic radiographs using doppler ultrasound. Methods: 3 patients with radio-opacities of the cervical region on digital panoramic radiographs were referred to doppler ultrasound for further diagnosis. Results: In 2 cases carotid artery calcifications were identified as an irregular radio-o...

OBJECTIVES To assess the prevalence of images suggestive of calcified carotid artery atheromas (ISCCAA) in panoramic radiographs of patients under dental treatment. MATERIALS AND METHODS The sample consisted of 8.338 panoramic radiographs from female (n=5.049) and male (n=3.289) patients under dental treatment between 4 and 94 years of age. The panoramic radiographs were evaluated searching f...

OBJECTIVES The purpose of the present study was to elucidate the significance of cone bean computed tomography (CBCT) for patients hoping to undergo implant-supported restorations of the maxilla. Therefore, two studies were planned. One was to compare the prevalence of anatomic variations and lesions in the maxillary sinus on CBCT of patients hoping to undergo implant-supported restorations of ...

Digital panoramic photography has become a popular tool to record landscapes, city squares or indoor scenes in a single image with a full 360° view. In photogrammetric applications, a digital panoramic camera may present an interesting alternative to conventional image acquisition techniques such as large format film or plate based cameras. Advantages of such a camera are their very high resolu...

INTRODUCTION Orthodontists assess mesiodistal root angulations before, during, and after orthodontic treatment as an aid in establishing proper root position. Panoramic imaging has been useful for this purpose and is a valuable screening tool in diagnosis and planning treatment of orthodontic patients. Cone-beam computed tomography (CBCT) for imaging of the craniofacial complex creates the oppo...

introduction the present work describes a study in which, based on patient dose measurements, thermoluminescent dosimeters were used to obtain the diagnostic reference level arising from panoramic radiography. materials and methods ten panoramic units and a sample of 15 patients per x-ray unit were studied. two thermoluminescent dosimeter chips were placed on the skin surface of selected organs...

Panoramic image pre-processing is one of key technologies in subsequent image processing and applications. An adaptive pre-processing multi-layer model for the sequences of panoramic images formed by six cameras is proposed in this paper. The algorithm develops a luminance classification criterion for different level of panoramic image based on the distribution of the statistical characteristic...
