Mammography experience
The height of the entire aluminum drone and photography platform angle (angle of generally 45. A 75. Between),[link widoczny dla zalogowanych], the patient's right arm on the edge of photography platform, so that patients resist the photo just right axillary upper right corner of the platform . _r for personnel hospitalized patients with the right hand on right shoulder. Shift to the shoulders; hold up his left hand gently pushed to the top of right breast in patients with photography platform, extrusion pressure plate along the sternum position, check the skin folds do not have the exposure. The left side of the same. 3. Lateral, if necessary, take additional lateral films. Bit as an example to the left (L-mi) adjusted to a 90 Mo target drone. A high degree of integration into the photographic platform rinse corner aligned with the patient in patients with sternal shank end face of photography platform, close to the patient's sternum photography platform, the platform under the chin on the photography side, left side of the elbow but also on the photographic platform on. -Q a square chin, the staff were into photography platform right hand, left hand to hold up to the top of the left breast in patients with advance photographic platform, compression plate compression along the rib location, check whether the breast skin fold, after measuring the thickness of the exposure. The right side of the same. Third, the photographic conditions: In recent years, more than mammography to digital photography (CR), photography relatively relaxed conditions, exposure conditions, the ionization of official control, but to ensure a certain degree of penetration (KV), keeping in mind that breast tissue must be seized In the ionization chamber window, were seized under the appropriate adjustments to the type of breast KV, if small breast, you can not cover the ionization chamber window, you need to manually select the projection conditions, then, should be based on normal operating experience, the same breast tissue. Pressed to select the thickness of the same KV and mAs: Also with digital photography (cR) should pay attention to IP board and matching the ionization chamber, this point is important when the installed capacity of the ionization chamber should be noted that the working curve to adjust to IP board optimum projection conditions. Should not the digital photography, then by ~ mtT_ for the accumulation of experience, according to the type and use of the machine were seized were to be pressed breast thickness and breast stern appropriate choice of the type of projection conditions. Fourth, note: 1. In the breast x-ray photography, it should only help the patient in the projection,[link widoczny dla zalogowanych], and relatively comfortable position. Projection when the appropriate pressure on the breast,[link widoczny dla zalogowanych], so that the thickness of the breast different front and rear to reduce, avoid breathing or posture movement blur. Improve the clarity of projection. 2. Operation should seek to maximize the display parts of the breast, the nipple is in tangential position as far as possible, should avoid breast skin wrinkling and skin thickening its image and confused. 3. Pressure should be kept to a minimum thickness of pressure, but if cancer is suspected should not be too heavy pressure, according to the breast lactation milk before exhaustion, it is a good show breast tissue, taken at the same time on both sides of the best films projection on each side are the oblique and axial projection in order to compare the reading of films on both sides, and accurately determine the nature of the lesion lesion. 4. Photo ionization chamber, must be according to the center of the breast on the corresponding ionization chamber window, it is very important,[link widoczny dla zalogowanych], otherwise it will result in inaccurate exposure conditions, affect the image quality. In addition to axial oblique and beyond, and sometimes require special projection spaces: such as: tangential position, arm position and so on. In short once you have the above points, we will be able to shoot high-quality breast pieces. (Received :2006-12-0 describes a photographic method of zygomatic David Lin Liu Shiming Liu Debin 88th Hospital of PLA, Tai'an City, Department of Radiology (271000) zygomatic bone examination in clinical trauma caused by more common, cheekbones The photo film is necessary to diagnose the illness, but the quality is good or bad radiography is often the key factors affecting the diagnosis. Used photographic methods of traditional top-jaw bit jaw top sites. Patients with difficult, low success rate radiograph, it is difficult to obtain satisfactory results, thus affecting the diagnosis. The author summed up the work of many years a kind of photographic methods, are presented below. Film Size: 8X10 inches, 10x12 inches horizontally. Film from: lOOem. Photo position: those who were seized prone on the photographic bed, head midsagittal plane and the vertical center line bed and overlap. Head thrown back, chin close to the bed,[link widoczny dla zalogowanych], listening to canthal line to appear before 35 ~ angle with the bed, two upper limbs straight, placed side (easy to measure the canthal line with the bed listening to the perspective), or elbow to the forearm release on both sides of the skull, hands take the bed (easily fixed head position.) Filter cassette placed on the activities of the thread under the bed tray. Centerline: the foot end of ridicule, but Gok 10 ~ ls, constricted by the two in the evening the whole burst film. Photo conditions: 72kv, 25mAs photos show: bilateral zygomatic, zygomatic arch and its adjacent soft tissue can be clearly outside the display. Experience: This photographic method is more simple zygomatic radiography position. Easy to learn, easy to patients with bilateral zygomatic show the same appearance, which will help about the control, to get good photographic results. (Received :2006-12-0
