Computed Tomography (CT)
Basic Fundamentals of Modality
Computer modality is the interaction between computers and humans, which can be unimodal or multi-modal (Karray et al., 2008). The fundamentals involve the usability of this interaction along with functionality. Functionality determines whether the purpose for which the interaction between humans and computer takes place is fulfilled or not. Usability is whether the adequate accomplishment of goals for which the interaction is created is effective in its range and degree. Humans use the most sophisticated machines, but there is no interaction if the purpose is not satisfied.
How Images are Produced
The images are produced by computerized x-ray beams coming out of the x-ray machines in computed tomography (CT) (National Institute of Biomedical Imaging and Bioengineering-a, n.a.). The light beams are aimed at a specific body area for which an x-ray is required. This main computer modality fulfills some purpose with interaction with humans. The signals created by the narrow light beams for generating an x-ray image produce a cross-sectional tomographic photo, a detailed depiction of the sliced body area. It is relatively better than the conventional x-ray since the digital stacking of three layers of the images is possible for letting the viewer observe a three-dimensional image. The tomographic images are visibly clearer for the physician to identify possible problems and make patient diagnosis easier.
Describe Two Procedures (Including Images)
The computed tomography (CT) scan is the basic procedure of modality through which images are taken. The patient has to lie in a tunnel-like machine that goes inside a hole where the scanning rays are exposed over his body (Zimlich, 2022). The specific area for which a CT scan is to be obtained is scanned with the radiation rays while the machine rotates. A series of images are taken to produce a 3D image of the particular body area, including slices and cross-sectional areas.
Another method could be Magnetic Resonance Imaging (MRI), which does not use x-rays and is a non-invasive technological method for producing images (National Institute of Biomedical Imaging and Bioengineering-b,...
…mentions that if an applicant has gained a bachelors, Masters, or Associates degree, they are suitable for sitting in the ARRT exam (Cleveland Clinic, n.a.). The well-qualified professionals are the ones who would be allowed to sit in the ARRT exam for the particular skill that they are aiming at, which could be Radiography Certification Examination, for example. Also, the applicants must meet an LCC counselor for confirmation about the degree requirements.The goals that need to be considered while attaining the education include completion of required courses, completion of competencies that are elucidated in Competency Examination Policy, completion of compulsory and elective competencies designated in the ARRT, completion of general patient care procedures and their relevant knowledge, fulfillment of regular and make-up hours of the degree, completion of developmental examination and correction that are necessary, tuition fee must have been paid in full amount, returning the reference materials or library books before graduating, completion of graduation survey, gaining signatures on the employer release form, and submission of a…

Computed tomography, more commonly know as a CT or CT scan, is an X-ray technique that is used to produce very detailed images of internal organs located in various parts of the body, such as the head, chest, and abdomen. Doctors use the images produced through this procedure to help diagnose and treat diseases. Other terms for the technique are also called computerized tomography or computerized axial tomography (CAT). While
The recent two reported cases also suggest that there may be many more similar incidences happening around unnoticed. The two contrasting examples of overdoses of radiation at hospitals confirms that if the hospitals accept their responsibilities properly and try to serve the patient's in professional manner, such types of accidental over exposure can be avoided. Instead of creating a medical terror, the reporter managed to provide relevant information in a
However, the increased use of CT scans in more of less careless and ill-advised practices will raise the concern of the effects it has on the health of the general public. It is therefore critical that the public is made aware of the associated risks and necessary education is conducted. The voice of all radiologists, clinicians, and technicians should advocate for the safe use of CT scans for both
Purchasing a CT Scanner Benefits and Costs of Purchasing A CT Scanner: A Comprehensive Evaluation "Each year, buyers of CT scanners faced much-improved choice sets; the question is how valuable those improvements were," and thus this is a review to explore whether or not the acquisition of CT scanners are actually worth a hospital committing to such an expensive effort (Ellickson et al. 2001 p 544). Overall, the health benefits of
