摘要:
The proposed test object for calibration of digital X-ray diagnostic apparatus refers to the field of medical technology and for calibration of digital X-ray diagnostic apparatus designed to determine the density of the bone tissue of the patient. The objective of the proposed technical solution is to increase the accuracy of the calibration of digital X-ray diagnostic apparatus by enabling calibration apparatus around the working field radiography. The objective is achieved in that known test object for calibration of digital X-ray diagnostic apparatus comprising the calibration elements of a homogeneous material, supplemented platform square shape with a side of 40 ÷ 50 cm, and a thickness of 4 ÷ 5 mm from a rigid material, weakly absorbing X-radiation on the outer surface of the applied site coordinate axes X, Y rectangular coordinate system OXY, the beginning of which is at the center of the square from the origin across the entire surface pad formed of meshes and steps ΔH = ΔY = 5 ÷ 6.25 cm, which set the calibration elements of the step shape with the minimum and maximum bone density is normal alleged object of study. The technical result of the claimed utility model is expressed in the expand arsenal of technical means of X-ray densitometry with high accuracy calibration over the entire working field of radiography. The proposed test object for calibration of digital X-ray diagnostic apparatus will find wide application in clinical radiology for calibration of digital X-ray apparatus during bone disease, e.g., vibration disease when diagnosing a patient.Предложенный тест-объект для калибровки цифрового рентгенодиагностического аппарата относится к области медицинской техники и предназначен для калибровки цифрового рентгенодиагностического аппарата, предназначенного для определения плотности костной ткани пациента.
