The objective of this work is to develop a segmentation model in order to remove the portion of lung for the treatment of certain illness such as lung cancer, and tumours. Image segmentation is the process of dividing an image into multiple parts. This method is vital to identify objects or other relevant information in digital images.During past few years we have gone across many region-based ...

Frequency-domain infrared photothermal radiometry is introduced as a dynamic dental diagnostic tool and its main features are compared with modulated laser luminescence for quantifying sound and carious enamel or dentin. Dental caries found in the fissures or grooves of teeth is very difficult to diagnose or quantify with the present clinical techniques. Visual examination and dental radiograph...

BACKGROUND The fissures of Santorini have long been known as a gateway for disease to pass from the external auditory canal to the periparotid and neck spaces. Although anatomically understandable, description of disease that originates in the parotid gland and extends through the fissures to the external auditory canal is rare. This is, in fact,the first presentation of such a patient at our i...

The City of Xian, China, has been experiencing significant land subsidence and ground fissure activities since 1960s, which have brought various severe geohazards including damages to buildings, bridges and other facilities. Monitoring of land subsidence and ground fissure activities can provide useful information for assessing the extent of, and mitigating such geohazards. In order to achieve ...

AIM Anal fissures are associated with hypertonia of the internal anal sphincter and pain. We evaluated the efficacy of local application of a combination of minoxidil and lignocaine in healing anal fissures. METHODS In this prospective, randomized, double-blind study, 90 patients with anal fissure were recruited. Patients received local applications of ointments containing 5% lignocaine (n=28...

Background: The author describes a technique of closed manipulation of the fibers of the internal anal sphincter to relieve anal spasm in patients with chronic anal fissures. Patients and methods: 301 patients with chronic anal fissures treated with this technique were enrolled for the study. Preoperative and postoperative anal manometry was recorded. An independent observer assessed postoperat...

PURPOSE This in vitro study was performed to correlate the presence of discoloration on occlusal surfaces with its histological depth and assess its influence on Diagnodent measurements in a group of permanent and primary teeth. METHODS Ninty-five primary and 95 permanent third molars were randomly selected from a pool of macroscopically intact teeth. One site of the fissure on each occlusal ...

Mars Orbiter Camera (MOC) images and Mars Orbiter Laser Altimeter (MOLA) data on the Mars Global Surveyor (MGS) spacecraft show evidence for three catastrophic outflow channels around the Cerberus Plains region, Mars. The morphologies seen in MOC images located within channels seen in gridded MOLA topography are similar to those found in catastrophic flood terrains on Earth, such as the Channel...

Segmentation is an important process in the field of medical imaging, as it can provide detailed information of an image. In this work, segmentation of pulmonary lobe is carried out which is useful for the clinical interpretation of CT images, to access the early presence and the characterization of several lung diseases. This segmentation process is challenging for severely diseased lung or lu...
