House of Wisdom - Essay Example It is impossible to envision Western civilization without fruits of Arab science. Al- khwarizmi’s art of Algebra, the well researched and explained medical teachings and philosophy of Avicenna, the new geography and cartography introduced by al-idrisi or the thorough rationalism of Averroes (Jonathan, 2009). It is evident how uneducated the westerners were. Their leader was an implacable cleric who had appeared from nowhere to massive popular acclaim; he exhorted his charges to holy war against the infidels with promises of a home in paradise. Diseases and malnutrition were rife. Medical care often involved exorcism or the amputation of the injured limb. Torture and other ordeals settled criminal cases. Few had any learning at all. The little education that they had consisted of memorizing out dated texts under the watchful eyes of hidebound doctors of religion. They did not understand basic technology, scien ce or mathematics. They could not date their most significant holy days nor could they chart the regular movement of the sun, moon and planets. Natural phenomena such as eclipse of the moon or a sudden change in weather terrified them; they thought it was black magic. Pope Uban II appealed to the princes in the French town of Clermont to end their ceaseless warring to turn their murderous energies on the unbelievers of the East. The fighting and denouncing of the Muslims by the European Christians and the Westerners began to obscure any recognition of the Muslim way of life and their contribution to science. This message consisted of four themes, some of which still resonate today. One was that Islam distorts the word of God, and the other was that Islam was solely spread by violence. The third one was that Islam promoted pervertedsexuality of humans by encouraging the practice of polygamy, for examp le, the way the sultans behaved in their Kingdoms, and through their excessively modest way they carried themselves out. Finally, they also believed that the Antichrist was a muslim(Jonathan, 2009). These were just prejudices because some of the European philosophers, who had earlier denounced the Muslim way of life, later appreciated and acknowledged their contribution to education (Jonathan, 2009). As most Westerners denounced the Muslims, an Englishman named Aderlard of Bath one of the early pioneers of the Arab teachings who brought about the wonder of astronomy geometry astrology and other fields to the medieval West, looked at the Muslims differently, he left his home in search for education. In addition, he believed that the Muslims had the best education. He had no interest in the debaucheries of his fellow Europeans. Unlike the holy warriors unleashed by Pope Uban II, he had the determination to learn from the Muslims rather than killing them under the sign of the cross. While the crusaders saw only evil in the Muslim infidel, Aderlard sought the light

Ultrasound Image Modality Assignment Example | Topics and Well Written Essays - 1500 words
Ultrasound Image Modality - Assignment Example Color flow imaging uses high-intensity pulse wavelengths that are 3 – 4 times longer than B-mode image pulses, with an equivalent spatial resolution decrease. In previous clinical trials, grayscale version of three-dimensional displays has been recreated to determine mitral regurgitation. Regurgitant mitral flow jets could hardly be differentiated from adjoining structures of the heart. A regurgitant mitral flow displayed in the color-coded three-dimensional image was developed but eventually proved to be ineffective because the display failed to incorporate cardiac structures. Failure of the regurgitant flow to supply spatial information, jet origin and its course of action led to the reconstruction of a more enhanced colored 3D regurgitant jet by a transesophageal approach with Doppler color flow mapping that displayed a combination of grayscale and color flow information. OBJECTIVE: To reveal the possibility of three-dimensional recreation of regurgitant mitral flow jets using the new method of color programmed digitized statistics obtained through transesophageal echocardiography (TEE). METHOD: 46 patients with detected mitral regurgitation on a prior transthoracic study and undergoing transesophageal echocardiography were evaluated. Patients with atrial fibrillation were not excluded from standard procedures. To measure regurgitant flow in 3D, a commercial ultrasound imaging system with a TEE probe was used. An alternation approach of data collection was employed for two-dimensional color flow images at 3-degree spaces above 180 degrees. Three-dimensional color flow jets were showed alongside grayscale information of the surrounding structures of the heart.
