achalasia is a well- defined esophageal motor disorder. graded pneumatic dilation using rigiflex ballon is one of the therapeutic modalities that had not been evaluated in a large long-term study. we aimed at evaluating long-term efficacy of graded rigiflex pneumatic dilation in the treatment of achalasia. symptomatic patients with achalasia who had been referred to our center were consecutivel...

In present time, in medical line there are many techniques have been researched for detect the TUMOR from human brain (medical image). Many techniques are available, Brain cancer detection in magnetic resonance images (MRI) is important in medical diagnosis because it provides information associated to anatomical structures as well as potential abnormal tissues necessary to treatment planning a...

We present an analogue VLSI circuit that performs morphological image processing operations on the focal plane. The circuit has been fabricated using a standard digital CMOS process. We exploit the parallelism of morphological image processing operations by using the massively parallel architecture of analogue VLSI arrays, achieving both high-speed and low-power computation [1]. The analogue ci...

What the algebra of convolution does for linear systems, the algebra of mathematical morphology does for shape. Since shape is a prime carrier of information in machine vision, there should be little surprise about the importance of the mathematical morphology. Now adays the operations of mathematical morphology are very much useful in object or defect identification required in industrial visi...

Retinal vascular region is recognized as the promising anatomical for diagnosis of several commonly seen diseases including cardiovascular related and diabetes. In this paper we propose two novel deep neural architectures named Dilated fully convolved convolutional network (FCNN) dilated depth concatenated (DCNN) to segment retinal blood vessels. The proposed work evaluated both with without di...

background achalasia is the most recognized motor disorder of the esophagus.because it is an uncommon disease, most studies have reviewed small numbers of patients. here, we report demographic, clinical features and treatment outcomes in 700 achalasia patients. methods in all patients, diagnosis was established based on clinical, radiological, endoscopic and manometric criteria. a questionnaire...

We describe a successful surgical treatment in a 2.5-year old boy with Loeys-Dietz syndrome, in whom we performed aortic arch and ascending aorta replacement with a valve-sparing operation (VSO) of the aortic root because of significant aortic insufficiency and dilation of the aortic root. We believe that VSO is ideal for treating young patients with aortic root aneurysm with normal or minimall...

Interpolation is an important processing step in 3D reconstruction. A new method, based on mathematical morphology, is presented here to implement the interpolation by means of a combined operation of weighted dilation and erosion. Compared with previously proposed methods, the new approach successfully resolves the interpolation problem when there is no overlapping area between the two objects...

A two-dimensional analog VLSI array that performs basic morphological image processing operations is presented. The system uses a smart pixel approach that facilitates the parallel computation of continuous real-time outputs. Photodetectors within the array of smart pixels also allow for parallel optical inputs. The processing is performed by current-mode circuitry implemented with CMOS technol...
