BACKGROUND Intraocular pressure (IOP) measurements are affected by the central cornea thickness (CCT). The conventional method for CCT measurement is ultrasonic pachymetry. However, noncontact procedures lower the risk of infection and corneal damage. In this study, we compared the CCT measured by Orbscan II, SP3000P, and ultrasonic pachymetry in patients with glaucoma or glaucoma suspect. ME...

Three children with left atrial myxomas are described. All suffered major arterial occlusion with consequent permanent morbidity before the diagnosis was made and the tumour removed. Each child had had previous small embolic phenomena. In two, the diagnosis was made by ultrasound. In any child who has had an arterial embolus without obvious cause, a left atrial myxoma should be considered and l...

ultrasonic machining (usm) is a mechanical material removal process used to erode holes and cavities in hard or brittle work pieces by using shaped tools, high-frequency and an abrasive slurry. this paper addresses the concept and development of an expert system (es) for hard and brittle material, such as glass, quartz, diamond, carbides, semi conducting materials, ceramic and graphite which ca...

Virtual reality is one of the intuitive man-machine interfaces, which uses human five senses. Virtual reality has many possibilities to enable medical doctor to understand diagnostic information intuitively and to do surgical operation more easily. In this paper, first of all, “What is Virtual Reality?” is introduced. After that, VR is applied to medical ultrasonic diagnosis to settle two probl...

uncommon. In DN, it is generally difficult to remove tumors without destroying normal anatomical structures because of the infiltrative and hypervascularized nature of these tumors. A 38-year-old male with NF1 visited our department because of slowly progressive hearing loss on the right side. His EAC was obstructed with a soft borderless mass around the external ear. We performed ultrasonic su...

To apply the ultrasonic 3D reconstruction method to measure the anatomic image data of lacrimal sac in the normal adult Chinese population, providing imaging anatomical basis for the clinical diagnosis and treatment of lacrimal duct diseases. 80 volunteers without lacrimal duct diseases were enrolled. The GE Voluson E8 ultrasonic diagnostic apparatus was used, with gynecological intracavitary p...

The present study was conducted to analyze the correlation between ultrasonic characteristics, pathological type, and molecular markers of thyroid-tumor-related genes as well as to evaluate the diagnosis and prognosis of thyroid nodules. The acoustic characteristics of 130 thyroid specimens were detected. Pathological sectioning and immunohistochemical detection were performed to determine the ...

Objective: To explore prenatal ultrasound diagnosis of VACTERL syndrome and partial caudal regression syndrome. Methods: 60 patients with VACTERL syndrome and partial caudal regression syndrome treated in our hospital during September 2011 to December 2013 were retrospectively analysed. The prenatal sonographic of patient was analysed taking the postpartum result as a standard. Results: Prenata...
