Abstract

An anti-collision method and apparatus for use with a C-arm x-ray imaging machine (10) to prevent damage to the imaging apparatus and injury to patients and health care workers includes a load cell (110), a differential buffer and integrator (120), an analog to digital converter (130), and a microcontroller (140) controlling the motor drive (150). The present application also provides a method for controlling the apparatus via a microcontroller (140) and includes the steps of determining whether an up / down switch is actuated (161), reading and comparing a value with a tabulated value (162), halting the C-arm (164) if the difference between the tabulated value and the recorded value exceeds a threshold value (163) and reversing the apparatus (165).

Description

technical field [0001] The present invention relates generally to the field of X-ray imaging systems. In particular, the present invention relates to a method and apparatus for collision avoidance of a C-arm X-ray imaging machine, thereby preventing severe collisions between the patient, the operator and the device itself. Background technique [0002] It is often desirable to perform x-ray examinations of a patient from a number of different locations, preferably often without repositioning the patient for the examination. A movable C-arm X-ray diagnostic machine as shown in Fig. 1 has been developed to meet these needs and is known in the medical and surgical fields. A C-arm x-ray machine is particularly useful in that it is small and mobile enough to be used in a procedural or examination situation without requiring the physician to repeatedly move the patient or require the patient to reposition in order to obtain a proper image. [0003] The term "C-arm" refers to a C...
