Nissin Brake Interview Questions and Answers

An average CT number water calibration test should be performed daily.

• Daily calibration tests are recommended to ensure accurate results

• Regular calibration helps maintain the accuracy of the CT scanner

• Failure to calibrate regularly can lead to incorrect diagnoses

• Calibration frequency may vary depending on the specific CT scanner model

The most common type of film used to record CT exams is the standard X-ray film.

• Standard X-ray film is the most commonly used film for recording CT exams

• It is cost-effective and readily available in most medical facilities

• The film is sensitive to X-ray radiation and produces high-quality images for diagnostic purposes

Ultrasound and MRI are likely to have less scan radiation compared to CT and X-ray.

• Ultrasound uses sound waves to create images, no radiation involved

• MRI uses magnetic fields and radio waves, no radiation involved

• CT scans and X-rays use ionizing radiation for imaging

Limitations of CT scanning of the spine include limited soft tissue contrast, radiation exposure, and inability to visualize certain structures.

• Limited soft tissue contrast can make it difficult to differentiate between certain tissues or pathologies.

• Radiation exposure is a concern, especially for repeated scans or in sensitive populations.

• CT scans may not be able to visualize certain structures well, such as nerves or small blood vessels.

• Motion artifacts can affect image qua...read more

A CT scan is a medical imaging procedure that uses X-rays and computer technology to create detailed cross-sectional images of the body.

• Patient lies on a table that slides into the CT scanner

• X-ray tube rotates around the patient, emitting X-ray beams

• Detectors measure the amount of radiation absorbed by the body

• Computer processes the data to create detailed images

• Images are reviewed by a radiologist for diagnosis
