Stereotactic Biopsy Unit

Accurate and efficient stereotactic biopsy

When the AMULET f or AMULET is used along with this optional Stereotactic Biopsy Positioner, it enables accurate and reliable procedure with high resolution images.

Features

Stereotactic biopsy examination with high resolution -50µm pixel pitch

The AMULET f is a full field digital mammography system which employs a direct conversion X-ray sensor panel. It is equipped with Fujifilm’s proprietary Direct Optical Switching Technology and a double layer of a-Se. This combination of material and technology enables image capturing at industry’s finest* 50 micron pixel pitch and with lower electronic noise simultaneously. This unique panel also realizes high DQE resulting in excellent image quality and reduction of X-ray dose. When this AMULET f is used along with the optional Stereotactic Biopsy Positioner, it enables accurate and reliable procedure with high resolution images.

Easy positioning of patients

Flexible positioning of tube and detector from -90° to +90° is available. Ergonomically designed arm rests and disposable soft pads help to make patients more comfortable.

It is possible to review previous examinations on the system for more accurate initial positioning. The Referral Image Viewing function requests and displays images of previous examinations stored in the PACS and makes positioning easy.

Targeting support functions / Safety functions

High resolution dual display system, targeting guide function on stereo images, various image processing and other useful functions make targeting accurate and easy.*1

An indication of needle depth within the breast is provided on the Biopsy device.*2
(This function helps prevent the needle from accidentally damaging the exposure table.)

Target position is shown via a diagram on the display screen. After determination of the target position, fine adjustment of the Z coordinate is possible.*3

Lateral approach (optional)

By attaching the lateral adapter, puncture can be performed not only vertically but also laterally to the compressed breast. Two puncture directions are now available, enabling wider application of mammographic needle biopsy.

Tomosynthesis: making it possible to observe the internal structure of the breast

In breast tomosynthesis, the X-ray tube moves through an arc while acquiring a series of low-dose x-ray images. The images taken from different angles are reconstructed into a range of Tomosynthesis slices where the structure of interest is always in focus.

The reconstructed tomographic images make it easier to identify lesions which might be difficult to visualize in routine mammography because of the presence of overlapping breast structures.

The Tomosynthesis function on AMULET Innovality is suitable for a wide range of uses, offering two modes to cater for various clinical scenarios. Standard (ST) mode combines rapid exposure timing and efficient workflow with a low X-ray dose while High Resolution (HR) mode makes it possible to produce images with an even higher level of detail, allowing the region of interest to be brought into clearer focus.

Two modes suitable for a range of clinical purposes

ST (Standard) mode

Acquisition angle: ±7.5°
Pixel size: 150/100 μm

The smaller angular range and fast image acquisition allow Tomosynthesis scans to be quickly performed with a relatively low x-ray dose.

HR (High Resolution) mode

Acquisition angle: ±20°
Pixel size: 100/50 μm

With a larger acquisition angle the depth resolution is improved. This allows the region of interest to be defined more clearly and brought into clearer focus.

Intelligent AEC optimizes the X-ray dose for each breast type

Intelligent AEC has advantages in defining the optimal dose for an examination compared to conventional AEC systems where the sensor position is fixed.

Through the analysis of information obtained from low-dose preshot images, Intelligent AEC makes it possible to consider the mammary gland density (breast type) when defining the x-ray energy and level of dose required.

Able to be used even in the presence of implants; intelligent AEC enables more accurate calculation of exposure parameters than is possible with conventional AEC systems. By allowing the use of automatic exposure for the implanted breast, Intelligent AEC can further enhance examination workflow.

Dedicated mammography AWS (Acquisition Workstation)

Optimal examination workflow
  • Integrated X-ray controller allows setting and confirmation of exposure conditions on a single screen.
  • Examination screen can be split and switched between 1, 2, or 4 image display.
  • Individual images can be immediately output to a PACS, viewer or printer during an examination.
  • Density and contrast can be easily adjusted while viewing images.
  • Alignment of left and right images can be adjusted both automatically and manually.

High definition second monitor (3M/5M: Optional)
  • A second, high resolution monitor can be added to the AWS making it possible to display previous images recalled from a PACS to ensure the mammographer has access to previous images at all times.
  • For Tomosynthesis, reconstructed images can be displayed and subjected to image QC.
