Description

Hand bone age imaging system with gesture reminding 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 function is reminded to gesture.

Background

At present, a certain proportion of examinees all over the world are caused to have different degrees of problems in growth and development of the examinees due to various reasons, and the examinees are short and small in body after development. If the examinees can make bone age examination as early as possible, doctors can find problems as early as possible, and if medical intervention is effective and necessary, the examinees can be helped to develop normally to a great extent, so that the examinees can reach normal height. Unfortunately, there is a period of validity for the medical intervention in these subjects, 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 subjects.

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 an examinee in a shielding room. Then, a doctor determines the bone age of the examinee according to the X-ray film of the left hand of the examinee, predicts the future height of the examinee and further determines whether the examinee develops normally or needs medical intervention. Unfortunately, in a shielded room, the left hand of the subject is imaged using an old film X-ray machine, or a new digital X-ray machine, with the radiation dose generally being high. A more serious problem is that when the X-ray machine photographs the left hand of the examinee, there are many scattered X-rays, and these scattered X-rays can scatter to the eyes, skull, and other parts of the examinee that are sensitive to X-rays when the examinee's X-ray protection is not made in place, thereby adversely affecting these examinees.

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

However, when the subject's hand is inserted into the imaging apparatus, the placement position of the subject's hand is likely to be not in conformity with the bone age imaging shooting requirements. For example, the subject's hand may be placed in an incorrect position or orientation, or may be gestured incorrectly, e.g., the fingers are not separated, or the fingers are not straight, which may lead to scrap, if not serious, reading and diagnosis by the doctor.
