Study of Digital Simultaneous Multi-plane Tomography Using Digital X-ray TV

Digital X-Ray Imaging

The use of X-ray image receptors that produce a digital image is becoming increasingly important. Possible benefits include improved dynamic range and detective quantum efficiency, improved detectability for objects of low intrinsic contrast, and reduced radiation dose. The image can be available quickly. The display is separated from the image capture so that processing and contrast adjustment...

Patient effective dose evaluation for chest X-ray examination in three digital radiography centers

Background: The radiation doses resulting from diagnostic X-ray examinations are routinely measured in terms of entrance surface dose (ESD) and effective dose (ED). In this study, for the purpose of radiation protection, the radiation doses received from Digital chest X-ray examination were evaluated in terms of ESD and ED. Material and Methods: The ED was calculated by using the MCNP ...

Digital Color Tv Telemetry

In most of the initial applications of digital TV telemetry the video source signal is monochrome (typically RS-170 standard). However color TV is now employed extensively in many of the government test ranges, and it is likely that it will be required to digitally transmit the NTSC color TV signal for security and other reasons. It is also likely that the bit rates which will be employed for t...

Using Tomography in Digital Plane to solve problems of Geometric Tomography

We study the problem of determining in a constructive way a convex body in the plane from its tomographic projections. For this, we consider the similar problem in digital plane: reconstructing a lattice convex set from its discrete tomographic projection. We show that we can use a reconstruction algorithm for the discrete problem to solve the continuous reconstruction to any precision. The pro...
