Problems solved by technology

[0007] Thus, although mobile radiography is in many ways more convenient than fixed-mounted radiography, its clinical utility is low due to poor image quality due to scattered radiation
Difficulty in achieving proper alignment of the focal spot with the anti-scatter grid is even more problematic in mobile radiography

Embodiment Construction

[0031] figure 1 and image 3 Shown is a system 100 of the present invention for aligning x-ray emissions from an x-ray machine and for adjusting grid lines in an anti-scatter grid to obtain a diagnosis with increased contrast and reduced noise due to scattered x-rays image information. The system 100 includes a portable x-ray machine 110 having an x-ray head 115 and an x-ray panel 150 for removably receiving an x-ray capsule or digital x-ray detector 155 . In one embodiment, the source locator 120 is attached to the housing of the X-ray head 115 of the X-ray machine 110 and the X-ray panel 150 is attached to the flexible filtering anti-scatter grid 160 . Both the source locator 120 and the flexible filtering anti-scatter grid 160 are mechanisms used to facilitate the acquisition of contrast-increased noise-reduced images compared to images obtained using prior art portable x-ray machines and prior art grids. small image.

Abstract

A grid employs dynamic and adjustable grid lines that communicates with a transmitting object and / or a receiving object. The grid lines may be but not limited to liner, crosshatched or pinwheel shaped. The grid may switch between opaque and translucent and the grid lines may target, calibrate to and track an object either transmitting or receiving. The grid may be employed as a filter or a privacy screen on a computer screen for instance. The grid lines are angled to match an angle of a user's position with respect to the grid.

Description

technical field [0001] The present invention relates to adjustable filters and, in particular, to dynamically adjustable filters and privacy systems. Background technique [0002] In a hospital environment, mobile X-ray imaging is performed on patients who cannot be moved or who are difficult to move. Mobile X-ray imaging accounts for a significant percentage of X-ray imaging exams performed in tertiary care medical centers. X-rays passing through an object, such as a human body, undergo some degree of scattering. Primary X-rays transmitted through the object travel from the X-ray source (also referred to herein as the X-ray focal spot) to the image receiver on a rectilinear path and carry object density information. The scattered X-rays form a diffuse image, which degrades the contrast of the main X-ray image. In some patients, the intensity of scattered X-rays exceeds that of primary X-rays. The scattering phenomenon is well known and is usually compensated for in gene...
