Page 264: Automatic Exposure Control (Aec)
Chapter 10: Image Acquisition Automatic Exposure Control (AEC) The Automatic Exposure Control automatically terminates an X-ray exposure to produce optimum qual- ity images. AEC automatically compensates for changes in patient thickness, opacity, and different tech- nique factors of mA, kVp, and SID. Proper patient positioning is very important. In extreme cases of misalignment, some radiation bypasses the patient and ends the exposure prematurely, causing under- exposed images.
Page 265 Chapter 10: Image Acquisition After the exposure has been completed, the console automatically displays the exposure time (mSec) and mAs values (Figure 10-19). Figure 10-19 Example AEC exposure completed (normal operation) The Applications software sets two limits for AEC operation: 512 is the maximum mAs. 2 seconds (2000 milliseconds) is the maximum exposure time.
Page 266: Ion Chamber Detectors
Chapter 10: Image Acquisition Ion Chamber Detectors Ion Chamber Detectors have three sensing areas (Figure 10-20). Sensing Area 2 is located at the center of the X-ray beam. While Area 1 and Area 3 can be selected to cover an exposure of two symmetrical parts of the body, such as the lungs or the kidneys, care should be taken to center the patient and receptor areas accordingly.
Page 267: Area 2
Chapter 10: Image Acquisition If the patient is improperly positioned and the sensing areas are exposed to direct radiation, the photo timed exposures will be too short and the films underexposed. The opposite is true if the patient’s tho- racic spine or sternum are positioned over the sensing areas. Note: Areas 1 and/or 3 are to be used with full-sized fields of 10x12 inches (254x305mm) or larger.

Many default tech- niques are AEC based in order to optimize image processing. The exposure time and mAs are automati- cally selected when you are in AEC mode, producing uniform quality images.
Page 270: Acquire Aec Images
Chapter 10: Image Acquisition Acquire AEC Images Acquiring images in the AEC mode requires precise light alignment and patient positioning. WARNING Collimation must be active over the AEC chambers being used or FIXED mode must be used in order to prevent possible patient over-exposure.

Page 324: Dual Energy
Chapter 13: Advanced Applications Chapter 13: Advanced Applications Dual Energy Overview Dual Energy (DE) is an optional imaging technique in which a low-kVp image and a high-kVp image are acquired in rapid succession. The acquired images are processed to create a soft-tissue image and a bone image, which are provided in addition to the standard (high-kVp for chest DE and low-kVp for abdo- men) image.
Page 325: General Guidelines
Chapter 13: Advanced Applications General Guidelines Dual Energy acquisition and processing algorithms are optimized for Chest AP/PA and Abdomen AP/PA on adult patients. Use of Dual Energy imaging on other anatomical views and/or pediatric patients may result in degraded image quality. For Dual Energy acquisitions, it is particularly important for the patient not to move or breathe during the exposure.
Page 326: Grid
Chapter 13: Advanced Applications Grid The processing algorithms are optimized for chest imaging with grid IN. Removing the grid may degrade image quality. Patient Dose Assuming correct selection of patient-size setting, the entrance dose (air-kerma) of the low-kVp exposure should be equivalent to that of the high-kVp exposure. For a typical two-view chest exam, the Lateral view dose is much higher than that of the PA or AP view.
Page 327: Copper Filtration
Chapter 13: Advanced Applications Low kVp Can be set anywhere between 70 and 85. In general, a lower low-kVp (default is 80) will result in better “tissue cancellation”. However, for large patients, slightly increasing the low kVp (e.g., to 85) may improve x-ray penetration and consequently improve the noise characteristics of the resulting soft-tissue and bone images.

Page 430: Tissue Equalization Overview
Chapter 15: Preferences Figure 15-42 Image processing preferences editor screen opened from the Viewer Tissue Equalization Overview Tissue Equalization (TE) is an advanced image-processing algorithm that improves contrast and visibility in over-penetrated and under-penetrated regions of an image without compromising the contrast in other regions of interest.
Page 431: Te Parameters
Chapter 15: Preferences Figure 15-43 Comparison with and without Tissue Equalization Skin No TE With TE Spine No TE With TE TE Parameters TE uses the information in the image to improve visualization. Two user-defined parameters; AREA and STRENGTH; control the extent and amount of TE that is applied to the image. There is an AREA and STRENGTH parameter for over-penetrated regions and an AREA and STRENGTH parameter for under- penetrated regions.
Page 432: Strength
Chapter 15: Preferences Strength The STRENGTH parameter affects the grayness of a region when TE is applied to it. For example, increas- ing STRENGTH for under-penetrated regions such as shoulders makes a white region grayer. Increasing STRENGTH for over-penetrated regions such as lungs makes a black region grayer. In both cases, increasing STRENGTH generally makes the region grayer.
Page 433: Electromagnetic Interference (Emi) Reduction
Chapter 15: Preferences Electromagnetic Interference (EMI) Reduction Overview Image artifacts can be caused when the Digital Detector acts like an antenna, picking up electromagnetic signals emitted by external equipment in the area. Artifacts are periodic lines or bands in the image. EMI artifacts can be intermittent, depending on external signals present, as well as the relative timing between the detector readouts and the peaks of the electromagnetic signals.

NOTE: If a detector is not communicating with a system, the bump event will be stored in the detector until the detector has reestablished communication with a system.
Page 438: Time Stamp
Chapter 15: Preferences Time Stamp The detector contains an internal clock which only recognizes actual time when connected to a system. Connection is made through wireless, tether or docking modes. The time noted in the timestamp column is the system time. In wireless mode, when the detector battery is removed the internal detector clock no longer has power to record time.
