Portable X-ray machine principle is incorporated imaging that can achieve the purpose of the perspective of small (micro) X-ray machine. Portable X-ray machine mainly by the X-ray tube and power supply and control circuit and other components, and X-ray tube and a cathode filament (Cathod) and anode target (Anode) and a vacuum tube, provides high voltage electric field so that the filament flow acceleration active cathode, forming a high-speed flow of electrons. High-speed electronic flow through the body, through a portable X-ray machine processing to generate perspective images.
Portable X-ray machine Structure
Portable X-ray machine mainly divided into two categories: one machine and its split type.
One machine captain usually 50-70CM, the machine features a portable design, when placed on a flat surface to work both ends of the machine are transmitting and receiving X-ray after treatment observation period by the image intensifier machine comes. For some high-end digital portable X-ray machine can usually AV video output or USB output connector to connect a computer or printer processing. You can use a dedicated storage suitcase to carry such a machine when not in use.
Another split type used for industrial inspection industries, the left and right ends of the machine placed on the level or up and down on the bench where special products for testing, relative to the whole volume of slightly more confidential.
Length × width × thickness 550 × 420 × 130/600 × 430 × 140
Net weight Φ50 4.2 Kg Φ75 5.2 Kg
Gross Weight Φ50 8.2 Kg Φ75 11 Kg
When the power is turned on, press the start button, the machine began to work.
Pulse signal sent by the master, by the power amplifier, voltage generates a high voltage to the X-ray tube anode, the pulse signal issued by the same masterⅡ enlarged to the X-ray tube filament, the X-ray tube to generate X-rays, and by number significantly panel displays the corresponding value KV /μA. In this case the object on the X-ray source and image intensifier between devices, image intensifier screen to show a clear picture is a perspective view thereof. To make the instrument stable and reliable work, the system uses pulse width modulation technology, the tube current, the tube voltage is kept constant, X-ray tube to work optimally. And a high voltage slow start function, the X-ray tube anode without high pressure overshoot phenomenon. Master controller uses micro chip devices, and to 20KHz frequency, so that the whole system efficiency is greatly improved, eliminating noise, provides the operator with a quiet environment, but also reduce the volume. Perspective instrument using high-frequency power supply high efficiency switching power supply, and a comprehensive protection measures. To ensure safety perspective instrument, machine plus a variety of protective devices, so that safe and reliable.
Portable X-ray machine Classification:
Apply in Medical
Medical portable X-ray machine is also known as portable X-ray machines for medical or medical X-ray instrument. Such X-ray machine is suitable for medical, mainly used in clinics, township hospitals, athlete training department and the school clinic and other departments. Because of its low cost, X-ray dose is low (high security), simple operation, small size, most can be connected to a computer for processing print, etc., to meet the equipment can not accommodate large-scale X-ray machines for medical equipment gaps, by many favor of the medical industry and workers.
Portable X-ray machine Methods of operation
1. before using the first check the appearance of the instrument case for damage during transport. Unpacking Check whether the host has traces of collision damage.
Then remove the host, will cover three notches aligned disc display three screws push the front end of the rotation angle can make a CD cover fixed.
2. machine power is turned on (the power plug into a ground wire single-phase three-hole outlet), switching power indicator light, hosts the DRO head light. Press
the self-locking start button, the DRO shows the X-ray tube anode voltage (KV) or anode current (μA) (depending on the selection switch may be), the instrument is
working properly, then the screen showed a yellow-green, will be measure was placed between the X-ray tube and the image intensifier, (object image intensifier
as close as possible), you can see the perspective image of the measured object on the screen, adjust the current (μA) on the digital display panel, voltage (KV)
adjustable knob until the image sharpness satisfied. Under the premise to ensure image clarity, it should be as low current (μA) a perspective.
3. when the hand self-locking start button is pressed, X-ray tube emit rays on the digital display panel lights work instructions, press the start button again
self-locking or regular time, X-ray tube stops (timing setting in about 1 minute).
4. the instrument should be intermittent use, if the continuous long working hours, more than the unit effective operating temperature range, this function
automatically shut down, this time in the digital display panel over-temperature indicator light, the need to stop for a moment until the temperature drops back to
resume work downtime depending on the ambient temperature.
