Highlights•Introduces a cutting-edge M-fiducial phantom for rapid and automatic ultrasound calibration, enhancing 2D to 3D image registration accuracy.•Demonstrates significant improvement in feature extraction capabilities over the standard N-fiducial phantom, especially limited field-of-view situations.•Describes robust closed-form solution algorithm that allows real-time computation anisotropic scaling improved calibration precision.•Provides empirical results showing technique's potential advance freehand ultrasound-guided surgery through high-accuracy, single-frame calibration.ABSTRACTThis study introduces novel phantom-based (US) technique aimed at improving procedures. The addresses limitations existing methods by accuracy. proposed method utilizes an extended version of designed facilitate with linear probe, particularly small scenarios. A incorporating enables precise transformation matrices was tested across varying depths evaluate performance point localization, length measurement, volume estimation. Results show method, combined solution, offers greater accuracy reliability compared manual methods. While in-plane measurements demonstrated high accuracy, out-plane estimations revealed limitations, wire phantoms increased depths. Despite these challenges, reduces operator workload enhances precision, making it promising approach high-precision interventions. Future work should focus on refining validating its efficacy clinical applications.Graphical abstractThe overview developed M-Fiducial Phantom
