Tomosynthesis Image Transmission Reducing Display Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tomographic images generated by tomosynthesis imaging have large amounts of data, leading to long transmission times and delayed display on external apparatuses, as existing methods require operator instructions or completion of examination before transmission can occur, resulting in inefficiencies and potential re-imaging due to recognition issues.
Innovation Solution
An image transmission apparatus that sequentially generates tomographic images, determines visual recognition by the operator, and automatically transmits these images to an external apparatus before operator instructions are given, using a reconfiguration unit, determination unit, and transmission unit to reduce waiting times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If tomosynthesis imaging is performed to generate high-resolution tomographic images, then image quality and diagnostic capability are improved, but data volume increases leading to long transmission times
Solution Approach 1:
The system performs tomosynthesis imaging and generates tomographic images before the examination is officially completed or before operator instruction is given. By preparing the images in advance during the imaging process itself, the system eliminates the waiting time that would otherwise occur between examination completion and image transmission, thus resolving the contradiction between maintaining high image quality and reducing transmission time.
2Reliability
If tomographic images are transmitted after examination completion or operator instruction, then data accuracy is ensured, but display timing is delayed
Solution Approach 1:
The transmission unit transmits tomographic images to the external apparatus in advance, before the examination completion instruction or transmission instruction from the operator is received. This preliminary transmission ensures that images are ready for immediate display without delay, while the system maintains reliability by using accurate reconfiguration of projection images obtained during the imaging process.
3Productivity
If automatic transmission is implemented without operator instruction, then productivity is improved, but risk of transmitting unrecognized or blurred images increases
Solution Approach 1:
The determination unit monitors whether tomographic images are being visually recognized by the operator during the imaging process. This feedback mechanism allows the automatic transmission unit to transmit images at appropriate times when they are likely to be recognized and verified by the operator, thus maintaining reliability while achieving automatic transmission and improved productivity.
Data Source
AI summary
A reconfiguration unit sequentially generates a plurality of tomographic images on each of a plurality of tomographic planes of a subject by reconfiguring a plurality of projection images corresponding to each of a plurality of radiation source positions. A determination unit determines whether or not at least one of the tomographic images is visually recognized by an operator. A transmission unit transmits the plurality of tomographic images to an external apparatus in a case where it is determined that at least one of the tomographic images is visually recognized by the operator.
