Ultrasound Bladder Size Analysis for Lower Abdomen Organ Screening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasound diagnostic systems lack the ability to efficiently determine the presence of organs other than the bladder in the lower abdomen, leading to potential omissions in necessary examinations.
Innovation Solution
An ultrasound diagnostic apparatus and method that analyzes bladder size from ultrasound image data to determine the presence of additional organs, such as the prostate and kidneys, and provides guidance for subsequent examinations based on bladder size, medical history, and standard examination protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If ultrasound image data is acquired and bladder size is derived, then diagnostic information is obtained, but the ability to determine presence of additional organs is lacking
Solution Approach 1:
The system performs preliminary determination of additional organ presence based on bladder size measurement before the actual examination proceeds. By calculating bladder volume from ultrasound images and comparing against threshold values, the system proactively identifies which organs need to be examined, preventing information loss about required examinations.
Solution Approach 2:
The invention introduces an intermediary processing step that uses bladder size as a mediator to infer the presence of additional organs. Rather than directly detecting all organs, the system uses bladder volume measurement as an intermediate indicator to determine whether prostate or kidneys are present and require examination.
2Reliability
If comprehensive examination of all organs is performed, then diagnostic accuracy is improved, but examination time and complexity increase
Solution Approach 1:
The system performs partial examination by selectively examining only those organs whose presence is determined through bladder size analysis. Instead of examining all possible organs universally, the system applies examination only where needed based on the measured bladder volume, maintaining diagnostic accuracy for relevant organs while reducing unnecessary examination time.
Solution Approach 2:
The examination protocol dynamically adapts based on bladder size measurements. The system adjusts which organs require examination according to the measured bladder volume, creating a flexible rather than fixed examination pathway. This dynamic approach ensures comprehensive examination of necessary organs while avoiding waste of time on organs unlikely to be present.
3Ease of operation
If bladder size measurement is used to determine organ presence, then examination guidance is improved, but measurement precision requirements increase
Solution Approach 1:
The system uses standard, readily available ultrasound imaging equipment to obtain bladder size measurements rather than requiring specialized precision measurement devices. The approach uses conventional ultrasound technology that is already widely deployed, making the examination guidance accessible without demanding extreme measurement precision through expensive specialized equipment.

AI summary
A processor (20) of an ultrasound diagnostic apparatus acquires first ultrasound image data of a lower abdomen of a subject, derives a size of a bladder region included in the first ultrasound image data based on the first ultrasound image data, determines presence or absence of an organ, other than a bladder, that is to be examined, in the lower abdomen based on the size of the bladder region, and in a case where determination is made that there is an organ to be examined, displays first information on an examination of the organ on a display (15).
