Summary
A new mobile computed tomography (CT) scanner allows for in-situ imaging with a translating gantry. This innovation enhances efficiency and safety for intraoperative and intensive care unit patients.
Area of Science:
- Medical Imaging Technology
- Radiological Engineering
Background:
- A novel mobile computed tomography (CT) scanner utilizes gantry translation for scan plane selection, enabling in situ patient imaging.
- This design facilitates computed tomography (CT) scanning of patients positioned on radiolucent surfaces within the gantry.
Observation:
- The mobile CT scanner is equipped with wheels, battery power, and a translating gantry, suitable for various clinical environments.
- Preclinical phantom studies demonstrated high image quality, with 0.8 mm spatial resolution and low-contrast detectability.
- Initial clinical experience confirmed the feasibility of intraoperative CT in 12 patients and routine bedside CT in 26 intensive care unit patients.
Findings:
- The mobile CT scanner achieved satisfactory spatial and low-contrast resolution in preclinical evaluations.
- Feasibility of on-demand intraoperative CT was confirmed in 12 patients.
- Routine bedside CT in the intensive care unit was successfully implemented in 26 patients.
Implications:
- Mobile CT can improve operating room efficiency by allowing shared access across multiple surgical suites.
- It enhances the safety and efficiency of CT for critically ill patients, reducing the need for transport from the intensive care unit.
