An anthropomorphic torso section phantom for ultrasonic imaging

Medical Physics, 1980
Using stable materials capable of mimicking any soft tissues of the human body—quantitatively with respect to speed of sound, density, and attenuation coefficient and semiquantitatively with respect to scatter—we have constructed a torso section phantom containing simulated bowel gas, kidney, kidney fat pad, liver, tumor, cyst, bony structures, and ...

An Anthropomorphic Breast Model for Breast Imaging Simulation and Optimization

Academic Radiology, 2011
Optimization studies for x-ray-based breast imaging systems using computer simulation can greatly benefit from a phantom capable of modeling varying anatomical variability across different patients. This study aimed to develop a three-dimensional phantom model with realistic and randomizable anatomical features.A voxelized breast model was developed ...

Anthropomorphic ResNet18 for multi-vendor DBT image quality evaluation

Medical Imaging 2020: Image Perception, Observer Performance, and Technology Assessment, 2020
Purpose: This work aims to develop an anthropomorphic convolutional neural network (CNN) classifier, based on the ResNet18 deep learning network and validate it for task based image quality evaluation of digital breast tomosynthesis (DBT) using a structured phantom with non-spiculated mass simulating lesions. Methods: The phantom is constructed from an

Anthropomorphic contour as a priori information in microwave breast imaging

2023 IEEE Conference on Antenna Measurements and Applications (CAMA), 2023
This work proves that qualitative imaging using induced current distribution could be used to perform microwave imaging of a realistic MRI-based breast phantom. Improvement of the spatial resolution is achieved by applying the Gerchberg-Papoulis algorithm associated with an anthropomorphic contour.

An anthropomorphic phantom for evaluation of radiosotope bone imaging of the lumbar spine

The British Journal of Radiology, 1983
The imaging characteristics of a radioisotope imaging device (camera, scanner, etc.) are usually assessed by measurement of fundamental physical parameters such as line spread function, modulation transfer function, counting efficiency, etc. Undoubtedly a list of such measured physical parameters characterising the system can be used as a basis for its
