Ultrasonography

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Area of Science:

Pathology
Medical Imaging
Health Informatics

Background:

Accurate gross examination of surgical specimens is crucial for disease diagnosis.
Optimized gross imaging workflows are essential for high-volume hospitals.
Commercial gross imaging systems are effective but often prohibitively expensive.

Purpose of the Study:

To design a streamlined and error-free gross imaging workflow.
To implement a cost-effective solution for gross specimen photography.
To evaluate the feasibility of UniTwain combined with a webcam for gross imaging.

Main Methods:

Lean techniques, including value stream mapping (VSM), were applied to workflow design.
A cost-effective technology, UniTwain, was integrated with a high-resolution webcam.
The new workflow was implemented and evaluated for efficiency and quality.

Main Results:

Mean process time decreased by 99.3% (from 600 to 4.0 minutes).
Process efficiency improved from 20% to 100%.
The solution demonstrated comparable durability, scalability, and archiving to commercial systems at a significantly lower cost.

Conclusions:

UniTwain with a high-resolution webcam offers a viable, low-cost alternative for gross imaging.
This approach streamlines workflow and is suitable for institutions with budget constraints.
The reduction in imaging time and cost does not significantly compromise diagnostic quality.
