“…Reported operator dose levels may approach or even exceed regulatory limits, which emphasises the need for both quantitative radiation monitoring and the use of appropriate protective measures during these procedures. (129) With regards to dose to the animal patient, few dosimetric studies have been published. Primary beam doses or entrance surface skin doses, typically of the order of 1 mGy, have been reported with the aim of assessing their contribution to personnel dose (Veneziani et al., 2010; Barber and McNulty, 2012). However, dosimetric publications aimed at the radiation protection of the animal patient are emerging.…”

Veterinary use of radiation in the diagnosis, management, and treatment of disease has expanded and diversified, as have the corresponding radiological protection concerns. Radiological exposure of personnel involved in veterinary procedures and, where applicable, members of the public providing assistance (e.g. owners or handlers) has always been included within the system of radiological protection. Veterinary practice is now addressed explicitly as the modern complexities associated with this practice warrant dedicated consideration, and there is a need to clarify and strengthen the application of radiological protection principles in this area. The Commission recommends that the system of radiological protection should be applied in veterinary practice principally for the protection of humans, but with explicit attention to the protection of exposed animals. Additionally, consideration should be given to the risk of potential contamination of the environment associated with applications of nuclear medicine in veterinary practice. This publication focuses primarily on justification and optimisation in veterinary practice, and sets the scene for more detailed guidance to follow in future Recommendations. It is intended for a wide-ranging audience, including radiological protection professionals, veterinary staff, students, education and training providers, and members of the public, as an introduction to radiological protection in veterinary practice. © 2022 ICRP.

“…The use of radiation in veterinary medicine demands responsibility to maintain rigid radiation safety standards and practice. Workers are often requested to restrain animals during the procedure to avoid movement artifacts and maintain image quality [ 1 , 2 ]. Therefore, the exposure of workers have to be minimized considering the radiation protection principles because of their presence in the examination room throughout the procedure [ 3 – 5 ].…”

Homogeneous Canine Chest Phantom Construction: A Tool for Image Quality Optimization

et al. 2016

Digital radiographic imaging is increasing in veterinary practice. The use of radiation demands responsibility to maintain high image quality. Low doses are necessary because workers are requested to restrain the animal. Optimizing digital systems is necessary to avoid unnecessary exposure, causing the phenomenon known as dose creep. Homogeneous phantoms are widely used to optimize image quality and dose. We developed an automatic computational methodology to classify and quantify tissues (i.e., lung tissue, adipose tissue, muscle tissue, and bone) in canine chest computed tomography exams. The thickness of each tissue was converted to simulator materials (i.e., Lucite, aluminum, and air). Dogs were separated into groups of 20 animals each according to weight. Mean weights were 6.5 ± 2.0 kg, 15.0 ± 5.0 kg, 32.0 ± 5.5 kg, and 50.0 ± 12.0 kg, for the small, medium, large, and giant groups, respectively. The one-way analysis of variance revealed significant differences in all simulator material thicknesses (p < 0.05) quantified between groups. As a result, four phantoms were constructed for dorsoventral and lateral views. In conclusion, the present methodology allows the development of phantoms of the canine chest and possibly other body regions and/or animals. The proposed phantom is a practical tool that may be employed in future work to optimize veterinary X-ray procedures.
