Description

Hand bone age imaging system with boundary induction function

Technical Field

The utility model relates to an intelligence medical science image diagnosis technical field, concretely relates to hand bone age imaging system with boundary induction function.

Background

At present, a certain proportion of children all over the world are caused to grow and develop to different degrees due to various reasons, and then the children are caused to be short and small after developing. If the children can make bone age examination as early as possible, doctors can find problems as early as possible, and medical intervention is actively carried out under the condition that medical intervention is effective and necessary, so that the children can be helped to normally develop to a great extent, and the normal height is achieved. Unfortunately, medical interventions for these children have a period of validity, and once the period of validity has passed, the effectiveness of the medical intervention is compromised or even completely ineffective. Therefore, timely bone age testing becomes very important for these children.

Accurate bone age testing generally requires the use of X-rays for imaging. At present, the common practice at home and abroad is to use an old-fashioned film X-ray machine or a new-fashioned digital X-ray machine to image the left hand of the child in a shielding room. Then, a doctor determines the bone age of the child according to the X-ray film of the left hand of the child, predicts the future height of the child and further determines whether the child develops normally or needs medical intervention. Unfortunately, in a shielded room, the left hand of a child is imaged using an old-fashioned film X-ray machine, or a new-fashioned digital X-ray machine, and the radiation dose is generally high. A more serious problem is that when the X-ray machine photographs the left hand of a child, a lot of scattered X-rays are generated, and when the X-ray protection of the child is not made in place, the scattered X-rays are scattered to the eyes, the skull, and other parts which are sensitive to the X-rays of the child, so that the children are adversely affected.

In order to eliminate the adverse effect of scattered X-rays on children, the latest X-ray imaging devices miniaturize the whole set of devices and then X-ray protect the whole set of devices to ensure that no scattered X-rays escape.

However, if one desires to protect the entire device from X-rays, it is generally desirable to use a lead sheath that is opaque to visible light. Therefore, when the hand of the child is inserted into the imaging device, the hand of the child is likely to be placed at a position that does not meet the bone age imaging shooting requirements. For example, a child's hand that is partially out of range for imaging can result in scrap film, affecting doctor's reading and diagnosis.
