Computed Tomography01:10

Computed Tomography

8.8K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Data Collection by Survey

9.1K
The systematic method of obtaining and analyzing accurate information of a population is called data collection. A survey is a standard method of data collection that involves collecting information from a target human population about their experience, opinion, or knowledge of a product, service, or process. The responses are recorded and interpreted. The most common survey examples are written questionnaires, face-to-face or telephonic conversations, focus groups, and electronic (e-mail or...

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Introduction to Surveying, Plane Surveying and Geodetic Surveys

1.1K
Surveying is the art and science of mapping the earth's surface. It involves measuring distances, angles in horizontal or vertical directions, and levels to understand the shape and size of land features. Surveying techniques are essential for various tasks, such as identifying the levels of a land area with reference to a specific point, and mapping undulations and water bodies.There are two main types of surveying: plane surveys and geodetic surveys. Plane surveys assume the earth is flat,...

National Nursing Organizations I

3.1K
Nursing organizations assume a significant role in consistently developing the nursing profession through education, research studies, establishing practice standards, and reforming health policies. Typically, nursing organizations operate at the regional, national, and international levels. For example, the International Council of Nurses (ICN) represents more than 28 million nurses worldwide. In contrast, the American Nurses Association (ANA) is a membership organization representing nurses...

Area of Science:

  • Medical Imaging
  • Radiology
  • Radiation Safety

Background:

  • Computed tomography (CT) dose management is crucial for patient safety.
  • Standardized dose data analysis practices are essential for effective radiation protection in radiology.

Purpose of the Study:

  • To assess the current practices of dose data analysis in Swiss radiological departments.
  • To evaluate the utilization of dose management software (DMS) and radiation protection activities.

Main Methods:

  • A nationwide online survey was conducted among Swiss radiological departments.
  • The survey comprised 19 questions covering general information, dose data analysis, DMS use, and radiation protection.

Main Results:

  • A 63% response rate was achieved from 152 participating departments.
  • 79% of departments regularly analyze dose data, with significant heterogeneity in frequency and methods (manual vs. DMS).
  • 42% use DMS, 58% use manual analysis, and 43% of manual users plan to purchase DMS.

Conclusions:

  • Swiss radiology departments demonstrate a commitment to radiation safety.
  • Heterogeneity in dose data analysis frequency, methods, DMS adoption, and radiation protection activities exists.
  • Further standardization in dose data analysis and reporting is recommended.
