Abstract The effect of segmentation on lung X-ray image classification has been analyzed in this study. 150 x-ray images study were separated into 78 as training data, 30 validation and 42 testing three categories: normal lungs, effusion cancer lungs. In pre-processing, the modified by adaptive histogram equalization to improve quality increase contrast. aims mark contouring area obtained from ...

Ingestion and deposition of fine particles on the surface coolant passage degrade blade’s cooling performance. This paper proposes a model to investigate complex characteristics during repeated collision, adhesion, rebound, removal events in small space inside typical impingement-effusion structure with double-wall blade. The results show that rarely collide wall escape directly from film hole ...

OBJECTIVE To assess the ability to detect and characterize middle ear effusion in children using A-mode ultrasonography. DESIGN Prospective nonblinded comparison study. SETTING Tertiary children's hospital. PATIENTS Forty children (74 ears) scheduled to undergo bilateral myringotomy with pressure equalization tube placement. INTERVENTIONS Before myringotomy, ultrasound examination of th...

BACKGROUND Several symptom-relieving interventions have been shown to be efficacious among osteoarthritis (OA) patients with knee effusion; however, not every symptomatic knee OA patient has clinical effusion. Results may be over-generalized since it is unclear if effused knees represent a unique pathological condition or subset compared to knees without effusion. The primary purpose of this st...

background and aims. the aim of this study was to assess the opening torque of grooved and non-grooved screws made of shape memory alloys (sma) for fixation of mandibular fractures. materials and methods. in this in vitro study the opening torques of ten sma screws with grooves and ten sma screws without grooves were compared in 20 holes (10 holes for grooved screws and 10 holes for non-grooved...

primary malignant neoplasms of the pericardium are rare and are predominantly mesotheliomas, followed by benign localized fibrous mesothelioma, malignant fibrosarcoma, angiosarcoma and benign and malignant teratomas. 1 this article concerns an atypical presentation of this malignant tumor with symptoms and signs of pericardial effusion. this unusual feature was complete encasement of the heart ...

the aim of this study was to compare the efficacy of antireflux therapy with both conventional management and those with no treatment in children with chronic otitis media with effusion (come). in this prospective randomized clinical trial ninety children with come which lasted more than 3 months or more, documented by physical examination and type b tympanogram in at least one ear without clin...

OBJECTIVES To assess the prevalence of inflammation in subjects with chronic painful knee osteoarthritis (OA), as determined by the presence of synovitis or joint effusion at ultrasonography (US); and to evaluate the correlation between synovitis, effusion, and clinical parameters. METHODS A cross sectional, multicentre, European study was conducted under the umbrella of EULAR-ESCISIT. SUBJ...

BACKGROUND Closed pleural biopsy (CPB) in patients with malignant pleural effusion is less sensitive than cytology. Ultrasound-assisted CPB allows biopsies to be performed in the lower thoracic parietal pleura, where secondary spread from pleural metastases is initially more likely to be found. We analyzed whether choosing the point of entry for CPB with thoracic ultrasound assistance influence...
