Development of a 3D printer using scanning projection stereolithography
We have developed a system for the rapid fabrication of low cost 3D devices and systems in the laboratory with micro-scale features yet cm-scale objects. Our system is inspired by maskless lithography, where a digital micromirror device (DMD) is used to project patterns with resolution up to 10 µm onto a layer of photoresist. Large area objects can be fabricated by stitching projected images ov...
متن کاملOrgan-specific SPECT activity calibration using 3D printed phantoms for molecular radiotherapy dosimetry
BACKGROUND Patient-specific absorbed dose calculations for molecular radiotherapy require accurate activity quantification. This is commonly derived from Single-Photon Emission Computed Tomography (SPECT) imaging using a calibration factor relating detected counts to known activity in a phantom insert. METHODS A series of phantom inserts, based on the mathematical models underlying many clini...
متن کاملA Patient-Specific Polylactic Acid Bolus Made by a 3D Printer for Breast Cancer Radiation Therapy
PURPOSE The aim of this study was to assess the feasibility and advantages of a patient-specific breast bolus made using a 3D printer technique. METHODS We used the anthropomorphic female phantom with breast attachments, which volumes are 200, 300, 400, 500 and 650 cc. We simulated the treatment for a right breast patient using parallel opposed tangential fields. Treatment plans were used to ...
متن کاملUse of a 3D printer to create a bolus for patients undergoing tele-radiotherapy
Background: This study describes the possibility of implementing three-dimensional printing technology to create a precise construction of a planned bolus, based on computed tomography information stored in the Digital Imaging and Communications in Medicine (DICOM) format file. Materials and Methods: To create the bolus with a 3D printer, we converted data in the DICOM format to the s...
متن کاملA system for evaluating magnetic resonance imaging of prostate cancer using patient-specific 3D printed molds.
We have developed a system for evaluating magnetic resonance imaging of prostate cancer, using patient-specific 3D printed molds to facilitate MR-histology correlation. Prior to radical prostatectomy a patient receives a multiparametric MRI, which an expert genitourinary radiologist uses to identify and contour regions suspicious for disease. The same MR series is used to generate a prostate co...
