History[ edit ] Before Lenna, the first use of a Playboy magazine image to illustrate image processing algorithms was in Roberts used two cropped 6-bit grayscale facsimile scanned images from Playboy’s July issue featuring Playmate Teddi Smith born Delilah Henry , in his MIT master’s thesis on image dithering. They got tired of their stock of usual test images, dull stuff dating back to television standards work in the early s. They wanted something glossy to ensure good output dynamic range, and they wanted a human face. Just then, somebody happened to walk in with a recent issue of Playboy. The engineers tore away the top third of the centerfold so they could wrap it around the drum of their Muirhead wirephoto scanner, which they had outfitted with analog-to-digital converters one each for the red, green, and blue channels and a Hewlett Packard minicomputer. This scan became one of the most used images in computer history. To explain Lenna’s popularity, David C.

These rays shoot out until they hit an object or wall, and that part of the wall is rendered in that vertical screen slice.

Are 3D and 4D scans more precise and effective than 2D scans?
Practical Obstetrical Ultrasound, p Rockville, MD, Aspen, Averaging the gestational ages derived from two or more measurements has been shown to be more accurate than using any single parameter. Because of the greater accuracy of the early study, ultrasound examinations subsequent to an early study should not be used to revise the estimated date of confinement EDC , but rather should be used as a measure of the quality of fetal growth between the two studies.

The museum, located in Silver Spring, Maryland, was established during the Civil War as the Army Medical Museum, a center for the collection of specimens for research in military medicine and surgery. So far, Means and his students have scanned and printed replicas of roughly 30 items in the museum’s collection. Among the highlights are a leg bone that healed poorly after being shot during the Civil War, a skull with a hole in it from a Civil War surgeon’s trepanation procedure, a mummified ear attached to a skull fragment that was donated in the early s, and a late 19th-century skeletal hand with a bullet hole from an area in the Midwest designated for Native American resettlement.
None of the remains being 3-D scanned is Native American. VCU’s Virtual Curation Laboratory has 3-D scanned and 3-D printed a number of specimens from the National Museum of Health and Medicine’s collection, including a mummified ear attached to skull fragment that was donated in the early s. Some of whom survived, some of whom did not,” Means said. For public programs, 3-D printed replicas allow visitors such as school groups to get a more hands-on experience with a museum’s collection, he said.
Brian McNeill, University Relations The collection is of particular interest to researchers focused on the history of battlefield trauma, as well as forensic anthropology. Terrie Simmons-Ehrhardt, a researcher in the Department of Forensic Science who studies forensic anthropology, specifically in forensic craniofacial identification and 3-D osteology, has been collaborating with Means on 3-D scanning bone specimens with a goal of creating a digital forensic osteology collection that would be accessible to anyone doing forensic research or education.

In this context of changing and challenging market requirements, Gas Insulated Substation GIS has found a broad range of applications in power systems for more than two decades because of its high reliability, easy maintenance and small ground space requirement etc. SF6 has been of considerable technological interest as an insulation medium in GIS because of its superior insulating properties, high dielectric strength at relatively low pressure and its thermal and chemical stability.
SF6 is generally found to be very sensitive to field perturbations such as those caused by conductor surface imperfections and by conducting particle contaminants. The presence of contamination can therefore be a problem with gas insulated substations operating at high fields. If the effects of these particles could be eliminated, then this would improve the reliability of compressed gas insulated substation.
It would also offer the possibility of operating at higher fields to affect a potential reduction in the GIS size with subsequent savings in the cost of manufacture and installation. The purpose of this paper is to develop techniques, which will formulate the basic equations that will govern the movement of metallic particles like aluminum, copper in a coated as well as uncoated busduct.
In recent years, the areas of industrial application of AC drives, especially Induction machine based on DTC technique has gradually increased due to its advantages over the other techniques of control. However conventional DTC suffers from high torque ripple and variable switching frequency.

It is usually part of an assessment called combined first trimester screening. Combined first trimester screening Combined first trimester screening assesses the risk for your baby having certain chromosomal abnormalities trisomy 13, 18 and This testing combines the nuchal translucency ultrasound with specific blood tests. Nuchal translucency ultrasound alone can also provide this risk assessment, but it is not as accurate as combined first trimester screening.
Combined first trimester screening is a non-invasive way of assessing your risk, which means it does not involve putting needles into the placenta or amniotic sac, as happens with CVS and amniocentesis. This means that combined first trimester screening simply tells us if your risk is low or high.

Obstetric ultrasonography is the use of medical ultrasonography in pregnancy, in which sound waves are used to create real-time visual images of the developing embryo or fetus in its mother’s uterus (womb).
The presence of a pregnancy and detection of the fetal heart can be seen from 6 weeks gestation by vaginal scan and from weeks by abdominal scan. Accurate measurements and images are taken of the gestational sac, the crown to rump length of the embryo, to accurately date the pregnancy, and assess the pelvic region to exclude pathology. This test is performed between These tests are designed to detect the three common birth defects: Please click here for more information about the Harmony and Panorama tests Chorionic villus sampling A chorionic villus sampling diagnostic test CVS is performed between weeks of pregnancy.
Using ultrasound guidance, a sample of placental tissue is taken using a needle inserted through the abdominal wall or fine forceps through the cervix. The tissue collected is then tested for chromosomal abnormalities. Preliminary results are usually available within working days with a full report available within weeks. Amniocentesis An amniocentesis is performed from 15 weeks onwards. Using ultrasound guidance, a sample of amniotic fluid is taken using a needle inserted through the abdominal wall.
The fluid collected is then tested for chromosomal abnormalities. Fetal anatomy scan Between weeks the anatomy of your baby is scanned in detail so that any information about the many body systems, such as the urinary tract, digestive tract, heart and major blood vessels, brain and others, can be imaged and interpreted.
