Use of anthropomorphic compressed breast phantoms for comparing ultrasound breast imagers
Archives of Acoustics, 2014 Two anthropomorphic breast phantoms were used to compare state-of the art ultrasound imagers. The phantoms mimic refractive effects at fat to nonfat boundaries, and include simulated and pathological structures like fibroadenomas, cysts, calcifications ...

Paediatric computed tomography diagnostic reference levels in Africa: A systematic review
Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 139-147, March 2025.Improvements in computed tomography (CT) technology have increased its applications in medical imaging. Variations in the paediatric DRLs indicate that harmonisation and standardisation of paediatric CT protocols are essential for the optimisation of paediatric doses. Abstract Introduction Improvements in computed tomography (CT) technology in terms of

Automatic Synthesis of Anthropomorphic Pulmonary CT Phantoms. [PDF]
PLoS ONE, 2016 The great density and structural complexity of pulmonary vessels and airways impose limitations on the generation of accurate reference standards, which are critical in training and in the validation of image processing methods for features such as ...

Wide-Angle Foveation for All-Purpose Use [PDF]
, 2008 This paper proposes a model of a wide-angle space-variant image that provides a guide for designing a fovea sensor. First, an advanced wide-angle foveated (AdWAF) model is formulated, taking all-purpose use into account.

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 165-172, March 2025.In 2020, our institution transitioned to the Eclipse™ treatment planning system and to Truebeam® linear accelerators with 6 MV and 10 MV energies. The linear accelerators were installed in smaller bunkers that could not accommodate 400 cm FAD. A multidisciplinary team within the institution was created to evaluate existing total body irradiation ...

Correction of megavoltage cone-beam CT images of the pelvic region based on phantom measurements for dose calculation purposes. [PDF]
, 2009 Megavoltage cone-beam CT (MVCBCT) is an imaging technology that provides a 3D representation of the patient in treatment position. Because it is a form of x-ray tomography, MVCBCT images give information about the attenuation coefficients of the imaged ...
