Patient-Specific Imaging Parameter Setting Without Test Scans

Solution Overview

Problem

Existing imaging procedures require lengthy and costly preparatory steps to adjust imaging parameters, often involving increased radiation exposure due to the need for test images to ensure desired outcomes, especially in medical imaging modalities like MRI and CT.

Innovation Solution

A computer-implemented method determines patient-specific imaging parameters based on patient and object data, including anatomical and procedural information, to optimize imaging settings automatically, reducing the need for preparatory efforts and radiation exposure.

Solution Approach 1:

The system performs preliminary actions by acquiring patient data (anatomical information, procedure type) and object data (implants, bone screws, virtual objects) before the actual imaging procedure. Based on this pre-acquired data, the system automatically determines and sets optimal imaging parameters in advance, eliminating the need for time-consuming test images and manual parameter adjustment during the procedure.

Solution Approach 2:

The system enables self-service by implementing an automatic parameter setting mechanism that uses patient-specific and object-specific data to determine imaging parameters without requiring manual intervention or test image acquisition. The computer automatically processes the data and sets parameters such as spatial position, spatial orientation, and display characteristics based on the input data, making the system self-configuring.
