Medical Display Brightness Control for Lesion Highlighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical displays lack the ability to focus a doctor's attention on specific lesions due to uniform brightness across the screen, leading to interference from surrounding images and reduced diagnostic efficiency and accuracy.
Innovation Solution
A method that uses a host computer and image processing unit to acquire and transmit coordinates, allowing for the display of a specific area at normal brightness while other areas are displayed at a reduced brightness, using adjustable shapes and proportions to highlight the target area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If uniform brightness is used across the entire display screen, then the display maintains consistent visibility across all areas, but the doctor's attention cannot be focused on specific lesions and surrounding images cause interference
Solution Approach 1:
The patent applies local quality by differentiating brightness levels across different regions of the display screen. Specifically, the display is divided into a first area (highlighted region) and a second area (surrounding region), where the first area maintains normal brightness to focus the doctor's attention on the lesion, while the second area displays at reduced brightness to minimize interference. This spatial differentiation of brightness quality directly resolves the contradiction between maintaining overall visibility and eliminating surrounding interference.
2Measurement precision
If the entire screen is displayed at normal brightness, then all images are clearly visible, but the doctor's eyes cannot be focused on the specific area and diagnostic efficiency is reduced
Solution Approach 1:
The patent implements local quality by creating distinct brightness zones: the first area containing the lesion is displayed at normal brightness to ensure clear visibility and accurate identification, while the second surrounding area is displayed at reduced brightness. This localized brightness differentiation enables the doctor's eyes to naturally focus on the high-brightness region containing the lesion, thereby improving both identification accuracy and diagnostic efficiency without sacrificing overall image visibility.
3Measurement precision
If the display uses different brightness levels for different areas, then the specific area is easier to identify, but the display complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the display screen into distinct functional areas: a first area for displaying the lesion at normal brightness and a second area for displaying surrounding images at reduced brightness. This spatial segmentation is controlled through coordinate information that defines the boundaries between areas, allowing the display system to manage different brightness levels for different regions without requiring complex overall control mechanisms.

AI summary
This invention discloses a method to control highlighting of certain part of image on a display, wherein the image processing unit forwards the physical coordinates acquired by the host computer's coordinate acquisition unit to the coordinate transmission unit, and draws a regular shape centered on the acquired physical coordinates, and then displays the area within the regular shape at the normal brightness, and the rest outside the area at the corresponding proportion of low brightness. According to the method of the present invention, the attention of the doctor is focused on the specific or targeted area, the interferences caused by the surrounding images and the brightness are shielded, and the images in the specific pattern area is easier to identify. Thus, it will help doctors to improve the efficiency and accuracy of medical diagnosis for a lesion and make medical consultation and education more convenient.
