Description

Technical Field

[0001] The invention relates to the technical field of X-ray photography auxiliary tools, in particular to a lumbar vertebra X-ray photography auxiliary body position placement device on a ship. Background Art

[0002] Among the auxiliary examinations for lumbar diseases, the most common is lumbar X-ray photography, including anteroposterior, lateral and oblique positions. Oblique photography is technically difficult: it requires that the angle between the human body's coronal plane and the X-ray detector be 45 degrees during photography. Due to individual anatomical differences and differences in operator skills, multiple shots are often required to obtain a satisfactory image when taking lateral shots, which increases the patient's radiation dose. The existing lumbar oblique X-ray photography is conventionally performed with the patient in a supine position. The patient lies on his back on a movable photography table with his body straight, the opposite side raised, and the lower limbs bent so that the side being examined is close to the table. The coronal plane of the body is 45 degrees to the table. Degree, through the auxiliary positioning of lumbar pillows, etc., this method is inconvenient to adjust the patient's position during positioning, and the patient is not easy to control the stability of the inclined position, which can easily cause image blur. Multiple shots increase the patient's radiation dose. Existing auxiliary devices such as lumbar pillows have problems such as easy sliding of patients, unstable fixation, and inability to maintain for a long time. They can only barely meet the requirements of lateral shooting and cannot coordinate with multi-angle shooting of frontal, lateral, and oblique positions. In addition, standing position can be used for oblique lumbar shooting, but when shooting on ships, it is easily affected by wind and waves. Standing position shooting of oblique lumbar spine is prone to shaking and lacks fixation function, which will also make the image blurred. Multiple adjustments increase the patient's radiation dose.
