Mobile x ray machine
Medical x ray equipment
This x ray machine is also called x ray equipment .
PLX100 x ray machine is the same as high frequency mobile x ray machine.
Usage of mobile x ray machine
The mobile x ray equipment is combined with high frequency X-ray video camera that can be conveniently moved to wards, ICU, operating rooms and so on for taking radiology photography for patients.
Technical parameters of mobile x ray machine
Power Output :2.5KW
Frequency :25kHZ
X-ray tube : fixed anode ,1.5mm
Power supply :220V ±10% ,50Hz
Operation Method : Wire/Wireless control
Features of mobile x ray machine
1. Structure is designed based on anthropotomy, with beautiful appearance, and it is easy to operate.
2. Two-button adjustment by kV and mAs, display by LCD and memory by parameters after power failure.
3. With a high-quality knockdown X-ray generator to reduce irradiation, which is much safer to environment and operator.
4. With 50 preset exposure programs, and can be modified and stored by the user for convenient operation.
5. The x ray machine is featured with protection for shortage of high voltage, over-flowing of tube current and output over-loading as well as indication for failure.
6. With a symmetrical beam applicator to adjust the X-ray field and a collimator lamp to locate the filed to ensure accurate radiography.

Bone age study (2)
The bone age study can help evaluate how fast or slowly a child's skeleton is maturing, which can help doctors diagnose conditions that delay or accelerate physical growth and development. This test is usually ordered by pediatricians or pediatric endocrinologists.
Bone age can be used to predict:
· how much time a child will be growing
· when a child will enter puberty
· what the child's ultimate height will be
The test is also used to monitor progress and guide treatment of kids with conditions that affect growth. Conditions for which a doctor will usually check and track a child's bone age include:
· diseases that affect the levels of hormones involved in growth, such as growth hormone deficiency, hypothyroidism, precocious puberty, and adrenal gland disorders
· genetic growth disorders, such as Turner syndrome (TS)
· orthopedic or orthodontic problems in which the timing and type of treatment (surgery, bracing, etc.) must be guided by the child's predicted growth
Through an x ray machine (mobile x ray machine or stationary x ray machine), can the bone age study can be done.
Bone age study (1)
A bone age study can help doctors estimate the maturity of a child's skeletal system. It's usually done by taking a single X-ray of the left wrist, hand, and fingers. It is a safe and painless procedure that uses a small amount of radiation. The bones on the X-ray image are compared with X-rays images in a standard atlas of bone development, which is based on data from large numbers of other kids of the same gender and age.
A child's bones, such as those in the fingers and wrist, contain "growing zones" at both ends called growth plates. These plates consist of special cells responsible for the bones' growth in length. Growth plates are easy to spot on an X-ray because they're softer and contain less mineral, making them appear darker on an X-ray image than the rest of the bone.
As kids grow, growth plates change in appearance on the X-ray images and become thinner, eventually disappearing (this is what is called "closed growth plates"). Because they look different at each age, a doctor can assign a bone age based on the appearance of the bones and growth plates. A child's bone age (also called the skeletal age) is assigned by determining which of the standard X-ray images in the atlas most closely match the appearance of the child's bones on the X-ray.
A difference between a child's bone age and his or her chronological age might indicate a growth problem. But such differences don't always mean there's a problem, because perfectly healthy kids can have bone ages that differ from their chronological ages.
