Characterization and evaluation methods of fused deposition modeling and stereolithography additive manufacturing for clinical linear accelerator photon and electron radiotherapy applications.

Purpose: To propose comprehensive characterization methods of additive manufacturing (AM) materials for MV photon and MeV electron radiotherapy.

Methodology: This study investigated 15 AM materials using CT machines. Geometrical accuracy, tissue-equivalence, uniformity, and fabrication parameters were considered.

3D printed heterogeneous paediatric head and adult thorax phantoms for linear accelerator radiotherapy quality assurance: from fabrication to treatment delivery.

. This study aims to design and fabricate a 3D printed heterogeneous paediatric head phantom and to customize a thorax phantom for radiotherapy dosimetry..

Establishing and developing a magnetic resonance-guided focused ultrasound program in a resource-limited setting: the Philippine experience.

Magnetic resonance-guided focused ultrasound (MRgFUS) is a non-invasive lesioning technique used to treat movement disorders such as essential tremor (ET), Parkinson's disease (PD), and X-linked dystonia-parkinsonism (XDP). We would like to report our experience in establishing and developing our MRgFUS program and preliminary results. Adult patients with tremor-dominant PD (TDPD), ET, and XDP were considered for initial screening (neurologic evaluation, skull density ratio [SDR] determination).
