Physics Magnetic Resonance Angiography ( Mra ) - 797 Words

Magnetic Resonance Angiography (MRA) is a technique in which magnetic pulses are used to image pictures of blood vessels inside the body. A MRA can be achieved using two techniques phase contrast and time of flight. A phase contrast can be done using complex subtraction and phase subtraction. A time of flight (TOF) can be done using dark blood and bright blood. A dark blood imaging is visualized using inversion recovery, saturation and dephasing. A bright blood imaging is analyzed using rephased /dephased, in-flow, use of contrast agents. Once a required MRA is processed, it is envisioned using a maximum intensity projection (MIP). A phase contrast works on idea of introducing two bipolar gradient pulses for flow compensation. Phase can†¦show more content†¦A phase unwrapping can be done using manual segmentation or automatic segmentation. A simple image processing region growing algorithm can be used to achieve that. A manual boundary drawing can be used to unwrap phase. In such a manual segmentation a phase or a magnitude image is preferred to be worked with. Flow uncertainty can be pictured in flow quantification and sources of error needs to be figured out and those should be resolved. The main sources are partial volume effect, poor segmentation and noise. Parameters like vessel size (actual vessel size, resolution), signal-to-noise ratio (SNR) (Scan parameters, blood velocity, velocity threshold), vessel segmentation accuracy (Segmentation method, SNR ) would rule the impact of these errors. Certain pixels that comprise of both still and moving spins would affect the phase value which does not reflect the correct/true velocity. Consider the flow is laminar and the assuming the magnitude signal behavior, this error can be demonstrated as a function of a vessel size. This would be the partial volume effect. A poor segmentation would be to miss some of the pixel that contains blood flow. Considering partial volume pixels were missed, this error can also be defined as function of the vessel. Noise can be denoted by considering the pug flow and ignoring the phase wrapping as ÏÆ'F/Fv ∠ (ve/vp)(1/SNR)(1/ÃŽ ») where ve and vp are venc and peak velocity respectively, while ÏÆ'F/Fv is the standard deviation of flow relative

Macbeth Tragedy Essays (554 words) - Characters In Macbeth

Macbeth Tragedy The downfall of Macbeth was a great tragedy. He knew it was not right to kill the king, but he felt he had no other choice. He was trapped into doing wrong. Lady Macbeth gave him the evil ideas throughout the play. She was his driving force. Without her, Macbeth wouldn't have done what he did. Therefore, Lady Macbeth is as much of a main character as Macbeth is. Macbeth says, "Stars, hide your fires; Let not light see my black and deep desires"(1.4.57-58). Here he is expressing that while he does want to become king and may have a few evil thoughts of how to achieve that dream, he does not plan to act on them. It is not until Lady Macbeth talks to him that he is a bit more convinced. Speaking of King Duncan, she states, "O, never shall sun that morrow see!" (1.5.71-72), basically ordering Macbeth to murder him in their own house. Lady Macbeth is obviously the evil one. That is apparent when she gets Macbeth's letter and responds by saying, "Yet do I fear thy nature. It is too full of the milk of human kindness"(1.5.16-17). This shows that she knows Macbeth will not murder Duncan on his own. She takes matters into her own hands and decides to convince him. Macbeth opens scene seven by giving a long list of reasons not to kill King Duncan. He is his ruler and kinsman, his guest, and a virtuous king. With this list of reasons Macbeth slowly convinces himself not to commit the murder. He then informs Lady Macbeth of his decision to "proceed no further in this business"(1.7.34). Lady Macbeth challenges that and calls him a coward, not a man. She accuses him of going back on his sworn word to her, and with very violent language declares that she would dash out the brains of her own baby, had she promised to as Macbeth had promised to kill Duncan. She then assures Macbeth that failure is impossible, at which point Macbeth is convinced once again to kill the king. Macbeth had resolved not to kill the king after much thinking about it, but Lady Macbeth persuaded him to do it. Not only did Lady Macbeth convince her husband to murder King Duncan, but she also made the arrangements to make it possible. At the beginning of Act two, scene two Lady Macbeth informs us that the guards are thoroughly intoxicated. She goes on to say, "I laid their daggers ready; He could not miss ?em"(2.2.15-16). Lady Macbeth made all the arrangements necessary for the murder of King Duncan, so that all Macbeth had to do was perform the act. In conclusion, Lady Macbeth convinced Macbeth to murder Duncan, convinced him again when he was unsure, and made all the proper arrangements which is why Lady Macbeth is as much of a main character of the play as Macbeth himself is. Macbeth did not want to murder Duncan in the first place until his wife talked him into it. Then, when he changed his mind, Lady Macbeth taunted him until he agreed once again to murder the king. Finally, Lady Macbeth made sure that everything was set up for the murder. On the surface it would appear that Macbeth was responsible for the murder since he committed the crime, but when more is read into it, it becomes clear that Lady Macbeth was more responsible.

Free Essays on Acropolis

Acropolis I. Introduction Acropolis (Greek akros, â€Å"highest†; polis, â€Å"city†), fortified natural stronghold or citadel in ancient Greece. The Greeks built their towns in plains near or around a rocky hill that could easily be fortified and defended. The word acropolis referred both to the hill and to what was built on it. Almost every Greek city had its acropolis, which provided a place of refuge for townspeople during times of war. Sometimes the ruler of the town lived within the walls of this stronghold. In many cases the acropolis became the site of temples and public buildings and thus served as the town’s religious center and the focal point of its public life and as a place of refuge. The best-known acropolis of the ancient world is the Acropolis of Athens. The ruins of its temples and their sculptures are widely regarded as the finest examples of ancient Greek art and architecture. Built on a limestone hill that rises about 150 m (about 500 ft) above sea level, the Acropolis dominates the city of Athens. It houses the remains of the Parthenon, a magnificent temple dedicated to the goddess Athena; the Propylaea, a monumental marble gateway and the main entrance to the Acropolis; the Erechtheum, a temple famous for the perfection of its details; and the Temple of Athena Nike....

Carl Rogers Research Paper Example | Topics and Well Written Essays - 2000 words

Carl Rogers - Research Paper Example In his early years, Rogers was a very shy and awkward child. He often went into tears for no reason and he was prone to sickness early. His brothers teased him often and made jokes about him. He grew up in a home where his father was often absent which meant that he grew close to his mother. As a young child, Rogers was the baby of the family and he remained the baby until he was five years old. As her grew older, his health became very strong. His older siblings paid special attention to him now and they taught him to read when he was four years old (Kirschenbaum, 1979, p. 2-3). He began to read everything he could find in his parents library which included several volumes of the bible and many other titles. Eventually, he began to entertain his brothers with the fantastic stories that he made up himself (Kirshenbaum, p. 4). As Rogers grew up he lived in many different places including a farm and the suburbs. Adulthood was fun for Rogers because he found it very easy to make friends. He had high energy and his health was excellent. These two factors allowed him to make journeys around the world. These journeys gave him a broader sense of the world around him early in his life. Central to Rogers early years was Calvinism which was the religious background his parents raised him in; eventually his mother would become a fundamentalist. By the time he entered college, he had changed to a more liberally religious viewpoint which led to fights in his home (Kirschenbaum, 1979). He would eventually develop ideas in existentialism as continued to study religion. As he developed his study of religion and other disciplines he began to believe that "good works were more important than ritual or doctrine in Christianity "Kirschenbaum, p. 29). In his view it was more important for people to take responsibility for their own actions than to rely on god to do something for them. He traveled to the Orient for some of his study and when he

Rhetoric analysis means making arguments or claims about the video game. Video games features in procedural representations of material, social, and cultural aspects of human experience (Bogost 123). Elsword is an example of a videogame representing the entertainment aspect of human experience. A lot of action movies are characterised by the villain and the good heroes who sacrifice a lot to eliminate the villains. The heroes always have exceptional skills which they acquire through training and experience. Like real action movies, this video game has heroes with unique skills, and missions to accomplish.
