The wavelength reduces with the increase of absorbed energy (Zettili, 2009).
The wavelength for visible light is in the range of 750nm-400nm. X-rays wavelength is in the range of 10nm upward. The wavelength of x-rays is extremely short as compared to the wavelength of visible light. The order of absorbency for x rays from the most absorbent to the least absorbent for the following materials is as follows: copper, glass, wood and air while the order of absorbency for visible light is as following: air, wood glass and lastly copper. From the list it can deduced that the order of absorbency of X rays is exactly vice versa to that of visible light for the mention materials (Kusky and Cullen, 2009).
When the produced x-ray is passed through the body, some part of the energy is absorbed by the body during the rest pass. The opposite side of the body is a plate containing a film that detects the X- rays and captures the attenuated x-rays. As x-ray emerges from the body, it contains an image in the form of variation in exposure across the image area. Variations are as a result of different rate of attenuation of x ray by the object. The plate is sprayed with powder that adheres to the charged areas hence electrostatic charge is formed. The heavily charged areas produce more detailed information as powder gathers more quickly in those areas.
X rays are more attenuated by denser material than light material; therefore bones will attenuate more rays than fats and muscles. From the above picture, the bones are clearly seen (denser material) while muscles, blood and fats cannot distinctly be seen. Shadings show them.
The CT scanner uses x-rays that are emitted in a fan shape to produce 3D images of objects. It has rotating gantry with x-ray tube mounted on it and arc shaped detector. When the x-ray beam is aligned by collimator and emitted, the rotating frame spins the tube and detector by 360 degrees

The relevant classical statement suggests that all adults “of sound mind” have the right to decide “what shall be done with” their bodies and any doctor who “performs an operation without his patient’s consent commits an assault”.3 In general, the principle of autonomy under UK law holds that when a patient refuses to submit to a recommended course of treatment, the attending physician is required to respect the patient’s decision unless it can be proven that the patient lacks legal competency.4 Thus the underlying right to autonomy depends on legal competency.
In this experiment, balloon, straw, scotch tape, monofilament and washer were used. A cut straw measuring 1.5 inches was mounted and secured on the middle part of the inflated balloon with one end of the straw was aligned with opening of the balloon. Five pennies were attached at the central part of the bottom of the balloon.
The doctor is supposed to fill the details with the prescription and then a bill is processed within the system. This ensures integrity and uniformity in the billing methods. Registration of the patient is also carried out within the patient. This is done by the patient supplying their details, which are stored within the system for future references.
Depression associated with a medical disease can manifest in various forms depending on its severity and relation to the signs and medications of the disease. Depression can be manifested in the patient completely devoid of any relation with the medical illness. It can be associated with the stress that is caused by the condition of the patient .
The first step was to identify the actors. An actor is a person, device or job role that interacts with the PDS. From the description below actors were identified which interacted with the system. They do carry out a given action in relation to the system.
Apart from the above mentioned categories, the other elements of the review analysis of a research article also encompass the evaluation of the validity of the research and conclusions. Thus, research plan, data collection process, data analysis process and data analysis results can be compartmentalized under validity checks of the research results.
For many people, Christian values and tradition play a strong role in the process of ethical decision making, and can play a significant part in the decisions that are made for any given patient. This essay will examine the process of ethical decision making within the case of Mrs.
CT and MRI are both widely-used in the field of lung cancer imaging, which refers to the identification of cancerous masses in lung tissue by means of CT and MRI among other methods of diagnosis.
This study examines the respective advantages as well as disadvantages of using both CT and MRI.
Below is a description of some of these uses:
1) Easy national/local data analysis: Because the CPT standardizes the medical services, it makes data analysis much easier. CPT could be used to track, record, and analyze trends in medical health services needs at
As a result, the EMR and CHIN are effective in the maintenance of confidentiality since only authorized practitioners are allowed to use the data. Another effectiveness of adopting the electronic records is that it will improve service delivery. This is
