Oncology
Medical Imaging
Computer-Aided Surgery

Background:

Radiofrequency (RF) hyperthermia is a novel technique for treating musculoskeletal tumors.
Accurate tumor visualization is crucial for effective RF hyperthermia treatment.
Current methods rely on preoperative imaging and intraoperative ultrasound, with a need for improved integration.

Purpose of the Study:

To develop a computer system for creating 3D tumor models from preoperative NMRI data.
To enable registration of the 3D model with patient anatomy using intraoperative ultrasound.
To contribute to a comprehensive computer-aided surgery (CAS) system for RF tumor treatment.

Main Methods:

Utilized segmented images from preoperative Nuclear Magnetic Resonance Imaging (NMRI) studies.

Developed a system to construct 3D models of tumors and adjacent bones.

Implemented a registration process using intraoperative ultrasound images segmented by surgeons.

Main Results:

A functional computer system for generating patient-specific 3D tumor models was developed.
The system facilitates the integration of preoperative and intraoperative imaging data.
The methodology lays the groundwork for a complete CAS system.

Conclusions:

The developed computer system aids in precise tumor localization for RF hyperthermia.
This technology enhances the reliability and efficiency of RF tumor treatment.
The system is a key component of a larger CAS project aimed at improving surgical training and outcomes.
