摘要： A system and method are disclosed for computing a radiation dose delivered to a patient during a computed tomography (CT) scan of the patient. The CT image dataset generated during the scan of the patient, and one or more parameters relating to a x-ray source are used to calculate the radiation dose delivered to the patient as a function of the CT image data set and the one or more parameters of the x-ray source. The radiation dose is generally found by calculating a primary x-ray dose distribution and scattered x-ray dose distribution from the CT image dataset and taking the sum of the primary x-ray dose distribution and scattered x-ray dose distribution.

摘要： An invention is described which uses quenchable phosphors to achieve a novel emission response in intensifying screens. The quenchable phosphor has the characteristic of reducing its efficiency of converting incident x-ray, gamma ray, or ionizing particulate radiations into emitted radiation in the ultraviolet (UV), visible or infrared (IR) regions of the electromagnetic spectrum when being essentially simultaneously irradiated by a spectrum of radiation of a specific range in the UV to visible to IR spectrum. The quenchable phosphor is combined with another class of phosphor, which emits the spectrum of radiation when struck by ionizing radiation which is similar or identical to the quenching radiation of the quenchable phosphor. These phosphors can be combined in a variety of geometrical manners, both homogeneously and heterogeneously, to achieve extended dynamic range and spatial frequency filtering for radiographic imaging systems. The invention has equal application for electronic imaging systems such as x-ray image intensifiers. In addition, a system comprising the quenchable phosphors can be built in such a manner as to overcome the optical stage quantum sink limitations in electronic imaging.

摘要： A hybrid grid-detector apparatus for x-ray systems wherein a microchannel plate structure has an air-interspaced grid portion and a phosphor/optical fluid-filled grid portion. The grids are defined by multiple adjacent channels separated by lead-glass septa. X-rays entering the air-interspaced grid portion at an angle of impingement upon the septa are attenuated, while non-impinging x-rays pass through to the phosphor/fluid filled portion. X-ray energy is converted to luminescent energy in the phosphor/fluid filled portion and the resultant beams of light are directed out of the phosphor/optical fluid filled portion to an imaging device.

摘要： An apparatus and method for measuring the volume of an object with particular application to measuring the volume changes in the limbs of patients suffering from lymphedema. The apparatus is comprised of a cylinder having a measurement chamber for placing a patient's limb. The chamber is sealed and a gas having known light absorption characteristics is injected into the chamber and mixed with the ambient air therein. A reference laser beam is projected through ambient air to a photocell on the cylinder and the optical absorption value of the reference beam is recorded. A second laser beam is projected through the air-gas mixture of the measurement chamber and the light absorption value is recorded. The ratio of the absorption value of the reference beam to the second laser beam is determined and this value is used to calculated a value which is proportional to gas concentration, which in turn is proportional to the volume of an object placed within the cylinder.
