Method of obtaining Caldwell's view. Caldwell's view (or Occipitofrontal view) is a radiographic view of the skull where the X-ray plate is perpendicular to the orbitomeatal line. The rays pass from behind the head and are angled at 15-20° to the radiographic plate. It is commonly used to get better view of the ethmoid and frontal sinuses. [1]
Waters' view (also known as the occipitomental view or parietoacanthial projection) is a radiographic view of the skull. It is commonly used to get a better view of the maxillary sinuses. An x-ray beam is angled at 45° to the orbitomeatal line. The rays pass from behind the head and are perpendicular to the radiographic plate.
Detail from The Extraction of the Stone of Madness, a painting by Hieronymus Bosch depicting trepanation (c. 1488–1516). Trepanning, also known as trepanation, trephination, trephining or making a burr hole (the verb trepan derives from Old French from Medieval Latin trepanum from Greek trúpanon, literally "borer, auger"), [1] [2] is a surgical intervention in which a hole is drilled or ...
Method of obtaining Schuller's view. Schuller's view is a lateral radiographic view of skull principally used for viewing mastoid cells. [1] The central beam of X-rays passes from one side of the head and is at an angle of 25° caudad to the radiographic plate. This angulation prevents overlap of images of the two mastoid bones. The radiograph ...
Greatly interested by the finds, Woodward accompanied Dawson to the site. Though the two worked together between June and September 1912, Dawson alone recovered more skull fragments and half of the lower jaw. [3] [4] The skull unearthed in 1908 was the only find discovered in situ, with most of the other pieces found in the gravel pit's spoil ...
A study, which was published in January in the journal Aging Cell, breaks down the different methods scientists use to measure biological aging, and suggest that some of these methods are better ...
Charles Hard Townes (July 28, 1915 – January 27, 2015) was an American physicist. [ 4 ] [ 5 ] Townes worked on the theory and application of the maser , for which he obtained the fundamental patent, and other work in quantum electronics associated with both maser and laser devices.
