Abstract
Изобретение относится к медицинской технике и может быть использована для диагностики как патологических, так и непатологических изменений в тканях молочной железы, для контроля за процессом лечения, а также для скрининга (предварительной диагностики с выделением «группы риска»). Технический результат заявленного изобретения заключается в повышении стабильности работы прибора, улучшении диагностических свойств и информативности электроимпедансных изображений молочной железы. Электроимпедансный компьютерный маммограф содержит корпус, на наружной поверхности которого расположены измерительные электроды. Внутри корпуса расположен соединенный с персональным компьютером управляющий микропроцессор, на платах которого расположены инжектирующий и измерительный каналы, соединенные линиями связи с дешифратором адреса и с выносными электродами инжектирующего и измерительного каналов. Инжектирующий и измерительный каналы расположены на двух отдельных платах микропроцессора, соединенных между собой наподобие сэндвича. Все токопроводящие части измерительного канала покрыты одинаковым металлом.SUBSTANCE: invention relates to medical equipment and can be used for diagnosing both pathological and non-pathological changes in mammary gland tissues, for monitoring the treatment process, as well as for screening (preliminary diagnosis with allocation of a "risk group"). The technical result of the claimed invention is to increase the stability of the device, improve the diagnostic properties and information content of the electrical impedance images of the breast. SUBSTANCE: electrical impedance computer mammograph contains a housing, on the outer surface of which measuring electrodes are located. Inside the housing there is a control microprocessor connected to a personal computer, on the boards of which there are injecting and measuring channels connected by communication lines with the address decoder and with remote electrodes of the injecting and measuring channels. The injection and measuring channels are located on two separate microprocessor boards, interconnected like a sandwich. All conductive parts of the measuring channel are coated with the same metal.
