purpose: to present 2 cases of acanthamoeba keratitis diagnosed by confocal scanning before positive results of smear and culture, and their successful treatment with combined medical therapy and corneal epithelial debridment. patients and findings: confocal scan was carried out in 2 contact lens wearers with a clinical diagnosis of acanthamoeba keratitis followed by corneal epithelial debridme...

results the study consisted of 40 patients (all men, with mean age of 33.38 ± 7.4 years). ct evaluation with standard dose were positive in 22 patients (55%). only 1 (2.5%) ct scan assigned as unacceptable by each radiologist in low-dose group. noise average of low-dose protocol, was approximately 7 times greater than standard dose group, while dlp and ed are 9.7 times smaller. in comparison wi...

bone scanning using the 99mtc-phosphate analogs is an established diagnostic modality and a commonly requested radioisotope examination for a variety of pathologies involving the skeleton, such as osteomyelitis, bony metastases, and occult fractures. the bone scan is one of the most commonly requested procedure in most nuclear medicine department. the images show areas of increased and decrease...

Selective laser melting (SLM), used to fabricate metallic objects with high geometrical complexity, is currently of increasing interest to the fields of medicine and dentistry. SLM-fabricated products should have highly smooth surfaces to minimize the use of post-processing procedures such as finishing and polishing. This study investigated the effect of various laser process parameters (laser ...

This paper illustrate the design and realization of control drive electronics of Limited Angle brushless torque motor for position control of Scan mirror mechanism. The scan mirror mechanism is controlled for the intended limited mechanical angle within +/20deg. The control drive is designed for six selectable positions within +/20deg with an accuracy of 0.75 degree. These six selectable positi...
