Embodiment Construction

[0028] exist figure 1 In an embodiment of the present invention, the device comprises a housing 1 made of a dielectric material, a container 2, at least one array 3 of transmitting probes 3a, at least one array 4 of receiving probes 4a, and a set of metal shells 5 and The electromagnetic absorber 6 made of foam, the shell 1 is used to receive the patient's breast, the shell 1 is arranged in the container 2, the set of metal shell layers 5 and the foam made Electromagnetic absorber 6 surrounds container 2 and arrays 3 and 4 .

[0029] The housing 1 held in the container 2 has an external shape (cylindrical in this example) complementary to the internal shape of the container. The housing has a hollow cavity for receiving the patient's breast.

[0030] The housing 1 is detachable relative to the container 2 . The device is connected to a set of housings 1 . The outer shapes of the housings in the set of housings are identical. But the cavities are different and can be adapt...

Abstract

To inhibit an increase in the number of encoder types. A servo system (S) is provided with: a motor (M) configured such that a movable element moves relative to a stator; an encoder (100) configured so as to detect a position of the movable element; and a control device (CT) configured so as to control operation of the motor (M) on the basis of a detection result of the encoder (100). The control device (CT) is provided with a first command transmission unit (210A) configured so as to transmit, to the encoder (100), at a first speed, a change command for changing an encoder-side communication speed to a second speed which is faster than the current first speed. The encoder (100) is provided with a speed setting unit (111) configured so as to change the encoder-side communication speed to the second speed in cases when the change command has been received.

Description

technical field [0001] The present invention relates to medical imaging systems with microwave antennas. [0002] More particularly, the invention relates to imaging systems of the type used for the analysis of human tissue or organs that are transparent to electromagnetic waves. [0003] The imaging system applies in particular and advantageously to the imaging of breasts. Background technique [0004] In microwave imaging systems, the choice of transition material between the antenna and the medium under observation is important to ensure proper penetration of the waves into the medium. The dielectric properties of the transition material must be selected according to the medium to be viewed in order to obtain better results in terms of image level. [0005] Furthermore, ideally, the transition material must have minimal dielectric loss, which limits the absorption of electromagnetic wave energy. [0006] To this end, it is often ensured that the antenna is immersed in ...
