OBJECTIVES This study was conducted 1/ to find out the effects of anatomical sites and implant types on the magnification and 2/ to evaluate the inter-observer variability on the evaluation using the digital panoramas taken at daily practices. STUDY DESIGN Panoramic radiographs from 156 patients treated with implants were evaluated by three observers. The length was measured on the lateral as...

A) Hematoxylin and eosin (H&E)–stained lung showing severe acute bacterial pneumonia with tissue necrosis (original magnification ×40). B) Brown and Hopps tissue Gram stained– lung showing abundant gram-positive cocci consistent...

OBJECTIVE To analyze whether less cumbersome loupes are as equally efficacious as the microscope for magnification for free tissue transfers in head and neck reconstruction. DESIGN A 7-year retrospective review of 151 consecutive microvascular free tissue transfers compares the operating microscope with loupe magnification. SETTING A tertiary care medical center. PATIENTS A total of 151 c...

The purpose of this study was to determine if the surgical operating microscope and/or dental loupes could enhance the practitioner's ability to locate the second mesiobuccal canal (MB2) canal of maxillary molars in an in vivo, clinical setting. The participating endodontists documented 312 cases of root canal therapy on maxillary first and second molars. Participants that used the microscope o...

The mesiobuccal root of the maxillary first molar has generated more research and clinical investigation than any other root. An inability to detect and treat a second mesiobuccal canal (MB2) is a reason for endodontic failure in maxillary first molars (1). Modifications in endodontic access and detection techniques, along with advancements in illumination and magnification technology, have aid...

Single-image super-resolution technology has made great progress with the development of convolutional neural network, but most current methods do not attempt high-magnification image reconstruction; only reconstruction ×2, ×3, ×4 magnification is carried out for low-magnification down-sampled images without serious degradation. Based on this, this paper proposed a single-image method, which ex...

background and aims. panoramic radiography is a method widely used because of low absorbed dose in patients (approximately 10 times less than that in the full mouth survey), reasonable cost and time. disadvantages of this radiography technique are magnification and distortion as a result of unequal magnification, which can influence dimensional and angular measurements used in clinical dentistr...

Big ecological changes often involve regime shifts in which a critical threshold is 22 crossed. Thresholds are often difficult to measure and transgressions of thresholds come as 23 surprises. If a critical threshold is approached gradually, however, there are early warnings of the 24 impending regime shift. Autocorrelation approaches 1 from below, variance and skewness 25 increase, and varianc...

[15]. Our implementation on the MasPar allows rendering with changing viewpoints of five frames/second and two frames/sec-ond for higher quality trilinear reconstruction on 128x128x128 byte volumes. This improves on previous results [2][3] [9][10][12] because of the better filters used, and we discussed the filter differences. Straight forward extensions to our techniques include coher-ency ada...

This technique combines the advantages of magnification and stereoscopic angiography. A heavy-duty x-ray tube oscillating between two positions (25 mm apart) allows serial spinal angiograms to be produced in stereo magnification (factor 2.0) using the 0.2 mm, 12 kW focal spot. The x-ray tube can be rapidly changed for normal serial angiography with a 0.6 mm, 50 kW focus. The technique is easy t...
