CT Scans. A computed tomography scan (CT scan, also called a CAT scan) uses computer-controlled X-rays to create images of the body. However a radiograph and a CT scan show different types of information. Although an experienced radiologist can get a sense for the approximate three-dimensional location of a tumor from a radiograph, in general.

Brighton Radiology's state-of-the-art Long View X-Ray machine has distinct advantages for both the operator and the patient.. Using Slot radiography technology, the whole spine and legs can be imaged as a single block. Images can be acquired with the table in any position from supine to standing — making weight bearing procedures easy.. To explore the improvement effect of SLOT Scan technology (narrow seam exposure capture technology) and the radiography techniques on the quality of the scoliosis X-ray films in teenagers. Methods The Sonialvision Safire II equipment of Shimadzu corporation and SLOT Scan were applied to take the radiography for 60 patients taller than 1.50 metres.

Scan equalization digital radiography (SEDR) implemented with an amorphous selenium flat-panel detector: Initial experience Xinming Liu, Chao Jen Lai, Lingyun Chen, Tao Han, Yuncheng Zhong, Youtao Shen, Tianpeng Wang, Chris C. Shaw. CCD technology was also introduced worldwide for full field mammography in the form of slot-scan technology. In this, the breast is exposed to an X-ray beam from the radiation head and the detector system consists of multiple linearly arranged CCD chips—i.e., a line detector.... Imaging systems with a smaller pixel size enable a better. A novel solid state detector has been developed for digital radiography. It is based on an assembly of CCD chips operated in TDI mode. The X-ray detection is achieved by a CsI scintillator layer which features a needle structure. It combines an excellent resolution with a high absorption efficiency. The detector is able to operate in 2 modes: a standard resolution mode and a high resolution.

The lack of vertical distortion, thanks to the JSB slot scanning technology and its unique reference plane positioning, provides true size images, in 1:1 scale, for highly accurate measurement.. The anti-scatter grid has been widely used to reject scatter and increase the perceptibility of a low-contrast object in chest radiography; however, it also attenuated the primary x-rays, resulting in a substantial loss of information and an increased relative noise level in heavily attenuated regions. A more dose efficient approach to scatter rejection is the slot-scan imaging technique.

New multilinear solid state detector for digital slot scan radiography.

Purpose: To evaluate the diagnostic performance of full-field slot-scan charge-coupled device (CCD)-based digital radiography in the detection of simulated chest diseases in clinical conditions versus that of two screen-film techniques: advanced multiple beam equalization radiography (AMBER) and Bucky radiography. Materials and methods: Simulated nodules and interstitial nodular and. Recently, the slot-scan digital radiography (SSDR) method has been introduced for chest and breast imaging as a new scanning technology of digital radiography. The system uses slot scanning geometry to acquire the radiography without the use of an anti-scatter grid. The narrow fan-like beam is synchronized with the detector when scanning a patient. Our purpose was to assess the diagnostic per-formance of eight different digital radiography chest systems for detection of simulated chest disease under clinical conditions. MATERIALS AND METHODS.... Best performance was observed with the charge-coupled device system with slot-scan technology, yielding a sensitivity of 46 % (132 of 288.

Figure 1. Digital chest imaging with a slot-scan technique. X rays are collimated into a narrow fan-shaped beam that moves across the chest simultaneously with the detector. The exposure settings are measured in the downward movement of the detector. The detector's upward movement represents the acquisition scanning process. The C-arm travels along the table length with a full body scan requiring 13 s, with smaller areas requiring proportionately less time [6, 8, 9]. Due to linear slot scanning radiography and several modifications to the imaging chain, the system achieves very low levels of entry and scattered radiation doses [6, 8, 9]. Only the abdomen and pelvis.

There was excellent correlation between EOS ® imaging and CT scan or manual measurements for all parameters except for the ISD,... Beaudoin G, et al. Diagnostic imaging of spinal deformities: reducing patients radiation dose with a new slot-scanning X-ray imager. Spine (Phila Pa 1976) 2010; 35:989-994. doi: 10.1097/BRS.0b013e3181bdcaa4. A more dose efficient approach to scatter rejection is the slot-scan imaging technique. Another problem in chest radiography is the low transmitted x-ray intensity in heavily attenuating regions. It results in a higher relative noise level, thus limiting the contrast sensitivity..

The sum of the effective doses for posteroanterior and lateral views for the slot-scan system (0.057 mSv ± 0.003 [± standard deviation]) was 34% lower than that for the full-field system (0.086 mSv ± 0.001, P <.05) at their respective clinical peak voltages (140 and 120 kVp, respectively).
