Benefits of technology

[0008] The object of the present invention is to provide a unique upright CT scanner that produces clinical quality images and is affordable enough for use in small hospitals, outpatient clinics, and doctors' offices. Instead of lying on a bed, a patient is either seated or standing during the examination. The X-ray source and detector are mounted on a platform instead of a gantry, translating while rotating. The distance between the X-ray source and detector, as well as the height at which they operate, is adjustable. The distance adjustment is particularly desirable because X-ray dosage can be reduced when the detector in

Problems solved by technology

This is not the optimal position for to examine for cardiovascular diseases because when a patient is lying down, his organs take more relaxed positions and thus it becomes more difficult to detect minute abnormalities.
However, it is not possible to eliminate the bed for conventional CT scanners.
Practically, however, his design has safety concerns and is probabl

Embodiment Construction

[0014] The principles of the invention will be discussed first in reference to FIG. 1. In this figure, patient 90 is standing on a stationary base platform 32 and holding handles 72 and 73, which are mounted to the ceiling by structures 70 and 71. The X-ray source is designated generally by the reference numeral 1. The two-dimensional digital X-ray detector is designated generally by the reference numeral 10. The X-ray source 1 is mounted to a horizontal linear motion mechanism 22, while the X-ray detector 10 is mounted to another horizontal linear motion mechanism 23. The combination of the linear motion from mechanisms 22 and 23 adjusts the distance between the X-ray source 1 and the detector 10. The mechanisms 22 and 23 can be controlled to move either individually or in tandem.

[0015] The linear motion mechanisms 22 and 23 are mounted to two vertical linear motion mechanisms, designated as columns 20 and 21, respectively. The joint motion provided by columns 20 and 21 adjusts th...

Abstract

In an upright CT scanner, an X-ray source and a two-dimensional digital X-ray detector are mounted on a rotating platform with a vertical axis of rotation. During scanning, the X-ray source and the detector are on opposite sides of the rotational axis for orbiting about a body to thereby scan it with pyramid-shaped X-ray beam. During scanning, the source and detector can be jointly translated along a horizontal axis that is perpendicular to the rotation axis and parallel to the detector surface, to scan a specific part of a body that is not centered or a body that is too large. The mounting height and distance of source and the detector can also be adjusted.

Description

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH [0001] Not applicable. BACKGROUND OF THE INVENTION [0002] 1. Field of Invention [0003] This invention relates examining the human body with X-ray by means of computed tomography, and more specifically, to a tomography apparatus that allows a patient to be scanned with his torso upright. [0004] 2. Description of the Prior Art [0005] X-ray computed tomography is one of the most frequently utilized modalities in diagnostic imaging. Recent developments in multi-slice CT technology have proven the diagnostic value of CT in areas such as cardiology. Since cardiovascular disease is currently the leading cause of death in the United States, it is desirable that cardiac CT scanners become a routine examination tool just as X-ray examinations have become, capable of being utilized in small hospitals, outpatient clinics, and doctors' offices. This requires a new generation of CT scanners that are more affordable, convenient to use, and able to d...
