title: [The problems of X-ray image formation in veterinary practice--result of a cyclic study with the use of a test phantom for the determination of image quality].
abstract: To grasp the problems of producing X-ray pictures in veterinary surgery, a ring trial was carried out. The task of the veterinarians was to produce two radiographs: from a certain body region, together with a test phantom, which allowed the judgement of the image quality immediately. The dates and technique of exposure had to be chosen as usual, one picture had to be developed in the dark room, either manually--the usual way with the normally used chemicals or by automatic developing machine. The other picture was developed under standard conditions in the Institute of Medical Physics. For a third radiograph, already exposed with the correct dose, only development was requested. Therewith the total process of producing an x-ray picture, the exposure dates and -technique and the dark-room procedure should be analyzed. Additionally a protocol was drawn up. All results were treated anonymously. The outcome of the trial obviously showed the problems: blatant tendency to overexposure, in no case underexposure, combined with faults in the dark room--e.g. disregarding the condition of the developer or the probably given necessity of changing the developer and even the importance of controlling time and temperature during developing. No informations were requested about fixation- and stop bath or the method of drying.(ABSTRACT TRUNCATED AT 250 WORDS)
