The introduction of multislice CT scanners and the associated dose increase compared to single and dual slice scanners has concerned many radiologists, health and medical physicists, as well as members of the regulatory community. Since multislice CT

This paper presents a calibration and correction method for detectorcell gain variations. A key functionality of current CTscanners is to offer variable slice thickness to the user. To provide this capability in multislice volumetric scanners, while

This paper presents a calibration and correction method for detector cell gain variations. To provide variable slice thickness capability in multislice volumetric scanners, while minimizing costs, it is necessary to combine the signals from several d

This paper presents a modification of the z-slope algorithm introduced in the accompanying paper 'An algorithm to correct for z-detector gain variations in multislice volumetric CT.' The x-expansion coefficients found by SVD are plugged into the equa

Large area contrast loss in image intensifiers results in reduced performance at low spatial frequencies and may limit the imaging capabilities of such systems for structures of clinical interest having inherently low subject contrast. The contrast r

It has been observed that image intensifier contrast ratio measurements taken on clinically installed systems always produce lower values than reported by the manufacturer. One common method of measuring the contrast ratio in the field uses the film

A simulation model of the stock market is proposed here. While it is not practical (nor desirable) to include all aspects of the stock market in our model, we do hope that the proposed market mechanism has captured a sufficient number of essential fe
