Freidina Ruler: history of creation and application

Freidin's ruler is a tool that is widely used in medical practice to measure the size of organs and tissues on radiographs.

The instrument was developed by Soviet radiologist L.M. Freidin in 1949. Freidin noted that X-rays do not always accurately determine the size of organs and tissues, which complicates the diagnosis and treatment of patients. To solve this problem, he created a special tool that allows you to measure the size of objects on x-rays with great accuracy.

Freidin's ruler is a transparent plastic ruler with marks in millimeters and centimeters on it. It has two scales: one for measuring length and the other for measuring angles. The ruler can be used both to measure the sizes of organs and tissues, and to determine angular parameters.

The use of the Freidin ruler can significantly increase the accuracy of diagnosis and choice of treatment method, especially in cases where it is necessary to determine the size of tumors and other neoplasms. Measurements using this ruler allow you to clarify the size of objects on radiographs and make a more accurate assessment of their condition.

Today, the Freidin ruler is used all over the world and is an integral part of medical practice. The tool is simple and easy to use, which allows you to reduce time and improve the quality of diagnosis and treatment of patients.
