Solution Overview
Problem
Existing radiation image capturing systems in medical settings face challenges with cable obstructions during surgeries and increased size/weight due to battery requirements for wireless communication, necessitating a solution to eliminate cables and reduce detector size and weight while maintaining high-quality image transmission.
Innovation Solution
A radiation image capturing system that uses a bed with a radiation detecting cassette connected via a minimally lengthened cable for wired communication and employs wireless communication with antennas positioned to avoid obstructions, utilizing a battery-powered transmission and reception processor for efficient data transmission and compression, allowing for cable-free operation and reduced detector size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable is connected to the radiation detector for wired communication and power supply, then communication reliability and power supply stability are improved, but the cable presents obstructions to surgical staff and may be imaged in the radiation image
Solution Approach 1:
The patent extracts the communication and power supply functions from the traditional cable connection and relocates them to a wireless communication module integrated into the radiation detector. This allows the detector to communicate with the control device wirelessly and draw power from an internal battery, eliminating the physical cable that obstructs surgical staff and appears in radiation images.
Solution Approach 2:
The patent replaces the mechanical cable connection system with a wireless communication system. The cable-based transmission of data and power is substituted by wireless data transmission via communication antennas and power supply via an internal battery, eliminating the mechanical obstruction while maintaining functional reliability.
2Ease of operation
If wireless communication is implemented in the radiation detector, then cable obstructions are eliminated, but the detector requires additional memory and battery which increases its size and weight
Solution Approach 1:
The patent optimizes the parameters of the wireless communication system by using minimal-capacity memory for temporary data storage during transmission and a compact battery design that provides necessary power without excessive weight. The communication module is integrated efficiently into the detector structure, minimizing the additional weight while maintaining wireless functionality.
3Ease of operation
If the cable length is optimized based on distance and subject dimensions, then cable obstructions are reduced, but the cable still requires connection points and may limit detector positioning flexibility
Solution Approach 1:
The patent removes the cable entirely from the system by implementing wireless communication. The connection points, cable routing, and length optimization problems are extracted and replaced by wireless signal transmission, providing complete positioning flexibility without cable management constraints.
Data Source
AI summary
A radiation detecting cassette is disposed in a desired position between a bed and a patient in an operating room. After a detector-side connector and a bed-side connector are connected to each other by a cable, an image capturing apparatus captures and records radiation image information of the patient in a radiation detector. The recorded radiation image information is transmitted from a transceiver of the bed to a console by way of wireless communications in a communication range selected by a selector of the bed, then processed by the console, and transmitted to a display device, which displays a radiation image based on the supplied radiation image information.
