Place the breast to be examined on the Bucky, making sure the breast is properly positioned over the photocell. An exposure during which the X—Ray exposure is made. Control console with rad shield screen. Note: If Rad Prep is released before the lamp is illuminated, the preparation is canceled. View more Mammography Unit devices for sale. When the green lamp is illuminated, preparation stops one second after release.
. Note: Pressing the compression pedals and moving the thumbwheels illuminates the centering light. Check limit force of programmed compression. The following selections are available via their keys: filter, focal spot, and film density control. Check resistance of belts in decompression. The kV readout displays the first letter of the code of the selected mode C, S, or D and the mAs readout displays the mAs values output. Compression system — — — — — — — 15000 exposures or 6 months Check belt tension.
Readout for messages and keys selections 5. The operator should use the cassette holder. Red light for cassette detection and exposure inhibit. When inserting a cassette in the Bucky, make sure that it is inserted all the way in and firmly held between the two stoppers. Surfaces should be scrubbed as needed using a soft sponge, gauze or cloth to remove all visible residue. E yy: Error message: fault inhibits the exposure. Process images with desired variations of brightness and contrast.
If fault to failure in equipment. Unknown X-ray Tube: What is the manufacturing date of the X-ray tube? Switch off the Senographe 800T. Column It consist mainly of a drive mechanism to hold and elevate the Examination arm. Switch on the Senographe 800T. To stop exposure immediately, release key. All hardware outside the generator cabinet is customer-supplied.
At end-of-travel there is no mechanical stop , the readout displays the minimum or maximum mAs values 4 or 600 mAs. The exposure will be inhibited. Taking advantage of the fast readout capability of the panel, a unique algorithm automatically optimizes the location of the measurement point under the breast for exposure control and thus eliminates cell positioning. The Manual mode is used to select kV and mAs values. The operator should maintain pressure on the button until the buzzer stops 8.
Note: The automatic decompression height that is being programmed represents the height from the last position of the compression paddle. However, the gantry and rad shield screen require a minimum amount of free space see Table 32 below. Vor Inbetriebnahme dieses Apparats sollte sich das qualifizierte und befugte Bedienungspersonal mit den geltenden Kriterien fr den gefahrlosen Strahleneinsatz durch sorgfltiges Studium des Hefts Nr. The Examination Arm can be rotated from +180° to —160° about this shaft. The Control Console, which is installed on the protective lead screen.
Correction is available in 11 steps -5 through +5. The Control console consists of the following keys see illustration 1—4 : 1. The machine will will do the exposure. The cassette holder must only be used in Magnification. Rad Prep activates green indicator lamp. Compression paddle change: Slide the paddle arm sideways from the compression paddle support.
If fault connection is faulty. Compression release button: Press to release compression. A pause during which the kV, and filter are put in place. It allows selection of the optimum kV, and filter combination in the selected priority. Equipment parts should be sprayed with a fine mist applicator or wiped with a wet cloth or sponge as directed by the instructions for use provided with the germicide. The Film-Holder Assembly can receive both the 18x24 and 24x30 Buckys, and the 18x24 cassette holder.
Other surfaces that may have casual contact with the patient and should be considered for intermediate level disinfection are the face shield and tummy shield. At the start of compression, the three priorities are displayed on the kV readout. It also means that you can ignore the message if a different, less dense, breast is to be imaged next or if different technical factors are selected. At end-of-travel there is no mechanical stop , the readout displays the maximum or minimum kV values 22 kV or 35 kV. However, it is possible, for special purposes such as physicist testing, to disable this interlock. The manufacturer is not responsible for any interference caused either by the use of interconnect cables other than those recommended or by unauthorized changes or modifications to this equipment. You can still work in Manual mode.
Note: Always make sure that the magnification plate is correctly locked in place before starting an exam. A buzzer sounds at the end of exposure. Front adjustment of the photocell position is accomplished via a lever located on either side of the film holder assembly. Maximum permissible pullstrength on each bolt: 310 daN 690 lbs. The left—hand section of the Control Console Keyboard is used to initialize or select generator parameters. Par consquent, toutes les prcautions doivent tre prises pour viter que les personnes non autorises ou non qualifies utilisent cet appareil crant ainsi un danger pour les autres et pour ellesmmes.
