High impact information on Radiographic Image Enhancement

• Bone mineral density (BMD) was measured by quantitative digital radiography (QDR) in 50 patients taking a vitamin K antagonist (warfarin) who were recruited from a large urban cardiology practice, and 50 age-, sex- and race-matched controls recruited from the community [1].
• These advantages along with the elimination of 153Gd source changes and Nuclear Regulatory Commission licensing requirements indicate that quantitative digital radiography is the superior method for spinal BMD measurements [2].
• CONCLUSION: Image quality with selenium-based digital radiography was comparable to that with conventional screen-film radiography and storage phosphor radiography [3].
• This paper describes and demonstrates an electronic collimation method, referred to as the alternate line erasure and readout (ALER) technique, for implementing slot-scan digital radiography technique with an amorphous silicon (a-Si) thin-film transistor (TFT) array based flat-panel detector [4].
• [IEEE Trans. Med. Imaging 11, 34-39 (1992)] for MTF calculation on digital radiography images [5].

Anatomical context of Radiographic Image Enhancement

• The aim of this study was to determine the in vitro diagnostic performance for approximal caries and occlusal dentine caries diagnosis of the Digora system for digital radiography in relation to the exposure time [6].
• Visual-tactile examination compared with conventional radiography, digital radiography, and Diagnodent in the diagnosis of occlusal occult caries in extracted premolars [7].
• The purpose of this study was to compare Schick CDR and Trophy RVGui direct digital radiography (DDR) systems for the ability to detect periapical lesions in human cadaver mandibles [8].
• Forty-nine root canals, 13 with verified lateral canals, were endodontically prepared and imaged using both conventional intraoral dental film (E-speed) and three modes of RVG-S digital radiography (normal, inverse, zoom) before and after introduction of Hypaque-M, 90% [9].

Associations of Radiographic Image Enhancement with chemical compounds

• Digital radiography with photostimulable storage phosphors. Control of detector latitude in chest imaging [10].
• Conventional, as well as digital radiography revealed caries in 7% of occlusal surfaces suspected of caries after a clinical examination [11].
• Clinical evaluation of digital radiography based on a large-area cesium iodide-amorphous silicon flat-panel detector compared with screen-film radiography for skeletal system and abdomen [12].
• A letter was sent to all GDPs in private care in Region Skåne, Sweden, asking whether they used digital radiography (n=513) [13].
• Myocardial flow distribution was visualized with resolutions between 0.1 x 0.1- and 1 x 1-mm(2) pixels, using digital radiography combined with the (3)H-labeled desmethylimipramine deposition technique [14].

Gene context of Radiographic Image Enhancement

• Recommendations for CRT design and selection for high-resolution digital radiography are included [15].
• Execution times for compression and decompression of the CT images with a PC-AT based digital radiography system varied from 24.7 to 18.5 seconds and from 16.2 to 5.1 seconds respectively, decreasing with higher levels of compression [16].
• Digital radiography of the hands and feet can be used in patients suspected of rheumatoid arthritis and in follow-up of those patients, because small and early erosions can be seen equally well with the digital technique as compared with the conventional film-screen technique [17].
• With plans to implement PACS, we evaluated computed radiography and digital radiography options [18].
• CONCLUSIONS: The performance of CCD-based digital radiography in detecting root fractures is similar to film-based radiography [19].

Analytical, diagnostic and therapeutic context of Radiographic Image Enhancement

• Comments on "Image Feature Analysis and Computer-Aided Diagnosis in Digital Radiography. I. Automated Detection of Microcalcifications in Mammography" [20].
• Myocardial microvascular perfusion after transfusion of liposome-encapsulated hemoglobin evaluated in cross-circulated rat hearts using tracer digital radiography [21].
• Diagnostic imaging is given particular attention, clarifying the difference between computerized radiography and digital radiography and explaining the accepted standard (DICOM) and the advantages of Web PACS [22].
• The PACS is an integrated system for the distribution and archival of medical images that are acquired by different imaging modalities such as CT (computed tomography) scanners, CR (computed radiography) units, DR (digital radiography) units, US (ultrasonography) scanners, and MR (magnetic resonance) scanners [23].
