What is the difference between a traditional CT Scanner and a Spiral CT Scanner?

marshyanke

I know that a spiral produces thinner slices and perhaps in more detail, I am not really sure? I would like to better understand the science behind it? Also, could you respond with some understanding of MRI and Doppler scans as well? Could you provide some of the history of the above mentioned diagnostic tests? Thank you.

Answer
Computed tomography (CT), originally known as computed axial tomography (CAT or CT scan) and body section roentgenography, is a medical imaging method employing tomography where digital geometry processing is used to generate a three-dimensional image of the internals of an object from a large series of two-dimensional X-ray images taken around a single axis of rotation. The word "tomography" is derived from the Greek tomos (slice) and graphia (to write). CT produces a volume of data which can be manipulated, through a process known as windowing, in order to demonstrate various structures based on their ability to block the X-ray beam. Although historically (see below) the images generated were in the axial or transverse plane (orthogonal to the long axis of the body), modern scanners allow this volume of data to be reformatted in various planes or even as volumetric (3D) representations of structures.

Spiral CT scanning is just a new and advanced from of CT scanning: This is a newer type of CT scan, also known as a 'helical' CT scan. It is faster than a standard CT scan and gives an even more detailed picture of your organs and tissues, including blood vessels. This can make it useful for picking up very small tumours. It's called a spiral scan because the X-ray beam rotates around you during the scan in a spiral shape. This gives the radiographers a continuous picture, with no possible gaps between the 'slices' of the scan.

steps to become a radiology technician?

I am currently a freshman at a state university. I am planning to earn B.S in Radiology science and become a radiology technician (not a radiologist), but I have no clue where to start. What do I have to do? how many years will it take ? (only 4-5 or more ? ) Please help me out. Thank you.
I wants to earn a BS in radiology and Masters in Health Administration

Answer
Radiologist technicians are health care professionals who specialize in using medical imaging to diagnose patients, evaluate injuries, and recommend treatment options. In order to become a radiologist technician, you will need to have earned a degree from an accredited college or university with a health care concentration. Additional on the job training is also required. When researching radiologist technician schools, look for programs that specialize in radiology and offer hands-on practice with cutting edge medical technology. Widely used technologies that students will need to become experienced with include X-rays, CT scanners, MRIs, 3D medical imaging programs, special cameras used in health care and surgery, sonogram machines, and plenty of other computer and web-based software programs.

Other important factors to consider when researching radiologist technician schools include the amount of funding and time spent on radiology research at the school and the size of the radiology department and team at the medical school hospital or clinic. If your medical school is a leader in radiology research and the expansion of medical imaging technology, then the quality of the academic and training programs will be high due to substantial funding and the on-campus presence of leaders in radiology. Medical centers that are known for excellence in radiology will also mean that your school program will benefit from the influence and teachings of experienced, cutting edge radiologists.
