Electronic Cassette Visual Identification via Camera Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical radiography, it is challenging for operators to identify the correct electronic cassette for imaging among multiple cassettes of different sizes and purposes, especially in environments where wireless cassettes require pairing with a console, leading to potential misidentification and failure in obtaining radiographic images.
Innovation Solution
A radiography system incorporating an electronic cassette, console, camera image acquisition unit, in-image cassette detection unit, identification information acquisition unit, collation unit, search controller, and display controller to visually assist in identifying the correct cassette by detecting and displaying the location of the use cassette within the camera's field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic cassettes are provided in the usage environment for different imaging purposes, then the versatility and adaptability of the radiography system is improved, but the ease of operation deteriorates because operators cannot easily identify the correct cassette among multiple units
Solution Approach 1:
The patent applies visual differentiation through color-coded indicators or labels on electronic cassettes to help operators quickly identify the correct cassette for specific imaging purposes. Different colors or visual markers are assigned to cassettes based on their intended use (e.g., pediatric imaging, adult imaging, different body parts), enabling rapid recognition without requiring operators to examine detailed specifications of each cassette.
2Ease of operation
If wireless electronic cassettes are used to improve mobility and ease of operation, then the ease of operation is improved, but the reliability deteriorates due to potential pairing errors between cassettes and consoles
Solution Approach 1:
The patent implements a feedback mechanism where the console and electronic cassette exchange identification information to confirm proper pairing. The system provides visual feedback to operators indicating whether the correct cassette is paired with the console, preventing pairing errors. This feedback loop ensures that even with wireless connectivity and multiple cassettes in the environment, the correct pairing is verified before imaging begins.
3Device complexity
If operators manually identify the correct electronic cassette among multiple units, then the device complexity is reduced, but the loss of time increases due to the searching and identification process
Solution Approach 1:
The patent applies preliminary action by pre-configuring identification information on electronic cassettes and pre-establishing pairing protocols between cassettes and consoles. Before the imaging procedure begins, the system automatically retrieves and verifies identification information, so that when operators need to select a cassette, the correct pairing is already confirmed or easily verifiable, eliminating the time-consuming manual search process.
Data Source
AI summary
In the radiography system, a camera image of the usage environment in which the electronic cassette is used is captured. An in-image cassette region of the electronic cassette is detected from the camera image. The cassette ID of the electronic cassette is acquired from the in-image cassette region. The acquired cassette ID is collated with the cassette ID of the use cassette set in the console to check whether the use cassette is present.
