The EqueTom™ User Manual – Tomosynthesis Image Quality and Case Studies contains a description of the tomosynthesis image forming principles, measurements, technical specifications, as well as clinical cases samples helping for learning images analysis basic principles.

Digital Tomosynthesis method description

X-ray digital tomosynthesis (DT) is a new method of examination in veterinary medicine. In terms of the simplicity of performing examinations, DT is close to digital radiography (DR), and in terms of efficiency, it is close to computed tomography (CT). The development of X-ray examination methods leads to an increase in the number of measured parameters of diagnostic images. DT provides new opportunities for both observation and measurement of image parameters of layers.

EqueTom™ (ET) tomosynthesis system for equine market is the world's first diagnostic mobile x-ray unit for examining horses using digital tomosynthesis method. It implements the principle - not bring a horse to CT, but bring CT to the horse. During the examining, the horse is calmly standing on a dry hard surface, and the operator places the ET device in the desired position.
