Frequently Asked Questions
Generator makes a loud sound during exposure
Yes, this is normal. The sound of an x-ray machines since the late 1890’s have been described as a rattle, buzz, burp, shake, vibration, etc. A typical 30kW generator pulls 50kW of incoming power, the same amount of power as: 50 microwave ovens set to full power 500 light bulbs rated at 100 W 5000…
Read MoreTube makes a lot of noise during prep and Expose
Yes, that’s normal. Summit supplied tubes are manufactured by Toshiba, and in general, the anode bearings will be heard while the tube is spinning. The bearing friction is used to ensure the anode does not coast (rotate) for extremely long periods of time, but instead stop within ~ 3 minutes. Tubes that spin for long…
Read MoreTube seems to make a THUMPING sound after ready (while holding prep)
This is normal. Once the tube is up to speed, the generator keeps the tube spinning by applying a 50ms pulse of power 4 times per second. This results in the thumping sound that is heard.
Read MoreThere are strange lines and shapes in my image
That is the Moire effect (google it). Determine if it is in the image or just in the monitor. Zoom in and out. If the identical moire lines appear no matter how much you zoom, then its in the image. If in the Image: Get a new grid with a slightly different Lines Per Inch.…
Read MoreDigital Image / Monitor flickers or has lines during x-ray
This happens once in a while with digital systems when proper cable layout is not taken into account during installation. X-ray machines are producing electric currents in the range of 1000 amps. This in turn creates huge Electro Magnetic Fields. These EMF fields will absolutely interfere with digital technology. This is normal (and occurs in HF…
Read MoreThe image shows radiation outside of the collimated area
Yes that’s normal. It is called OFF FOCUS RADIATION. This is radiation scattering as it hits the table/tray/receptor/patient/walls/floor/etc, and coming back to the image receptor. What can be done? NOTHING. This has always been there and it will always be there. Is it something to be concerned about? In regards to image quality: No In regards…
Read MoreWhat system setup would result in the greatest image resolution (highest lp/mm)
Step 1: Ensure a good incoming radiation Signal: Fractional focal spot tube (smallest focal spot possible for sharpest image) High resolution grid (178/200/215 LP/inch, more gridlines less scatter) Bucky (Clean the incoming signal without software filtering) Automatic Exposure Control (adjusted to always acquire the bare minimum panel radiation to avoid grainy images) High Frequency Generator…
