Dedicated Breast PET System
AC19-0021
The system was commercialized based on a prototype developed under the
project "Development of Molecular Imaging Equipment for Supporting
Medical Treatment of Malignant Tumors and Other Conditions" (from 2006
to 2009) funded by the New Energy and Industrial Technology Development
Organization (NEDO).

The morbidity rate of breast cancer keeps increasing each year and peaks at the
prime of life. Therefore, we developed a completely new type of breast examination
system based on our desire to save as many women from breast cancer and help
them remain vibrant at home or their workplaces as long as possible. That system is
the Elmammo Avant Class dedicated breast PET system.
Ever since the birth of PET systems, Shimadzu Corporation has been diligently
developing new systems and offering state-of-the-art technologies. Now we have
taken all the PET technology we developed thus far and incorporated it in the
Elmammo Avant Class to offer new clinical value for diagnosing breast cancer patients.
Note: The name Elmammo was formed by combining "Elm," a tree that symbolizes trust in the language
of flowers, with "Mamma,"
Born to Be Gentle, a PET Scanner for Women
Dedicated Breast PET System
I m a g e B r e a s t G e n t l y
Patient Comfort
Created Out of Compassion for Women
Breast examinations are sensitive examinations. To minimize the burden on
patients during examinations, the system was designed from a woman's
perspective by incorporating feedback from women throughout the design.
The gentle shape of the design softens the first impression the patient
receives when entering the examination room and helps reduce anxiety
before the examination.
Offers a Gentle Examination Space
Comfortable Examinations
An indentation provided in the bed surface near
the head makes it easier to lay comfortably in the
prone position. The bed is made of a dual structure,
with a soft material used for the mat in direct
contact with the skin and a harder material
required to maintain proper posture used internally.
That means the bed is both comfortable and easy
to set up during examinations. For optimal hygiene,
the materials are also easy to clean.
Preparation for Examination Is
Also Patient-Friendly
The bed height was optimized to make it easier
for patients to get on and off the bed and easier
for medical personnel to provide assistance. The
bed is also surrounded by gentle curves to prevent
patients from bumping any sharp corners when
getting on or off the bed.
Detectors are arranged in a circle surrounding the
breast. The patient is examined in a relaxed
position, with the breast simply placed
comfortably in the detector hole. Because it does
not compress the breast, there is no compression
pain involved.

Simple Setup Process
Setting up the examination is easy, because the Elmammo Avant
Class doesn't require breast compression. Simply have the patient
lie face down on the bed, with the breast positioned in the
detector hole. That is all the preparation required for examinations.
Lying in the prone position inhibits breast movement during
examinations, so that examinations can be performed with
confidence. It also means patient setup can be accomplished very
quickly, with minimal exposure to medical personnel to provide
assistance.

Advanced Technology
Comparison of Whole Body PET and Elmammo Images
The higher spatial resolution achieved
results in rendering even more detailed
drug accumulations in tissue more
clearly than conventional whole body
PET systems (in a comparison by
Shimadzu).
In a comparison of mini-DERENZO
phantom images, the whole body PET
system did not properly render 2.4 mm
and smaller rod sizes, whereas the
Elmammo rendered them clearly.
State-of-the-Art DOI Technology Optimized
for Breasts
Using smaller detecting elements reduces the probability
(sensitivity) of detecting radiation. To ensure high sensitivity for
detecting even tiny amounts of radiation after a whole body PET
examination, the system positions the detectors as close to the
breast as possible and is the first clinical PET system in the world to
include DOI technology*1. Due to a unique detector configuration
and algorithm, the system provides far more information and
higher precision than a whole body PET system.
Ensures High Quantitative Analysis Capability
The higher resolution reduces partial volume effects*2 and helps
ensure quantitative analysis capability. High quantitative ability
was ensured by applying the absorption and scattering correction
technology we have accumulated from developing whole body
PET systems. The system also supports SUV diagnostics*3, which
involves numerically evaluating the malignancy level of lesions.
Configured with 1.44 mm square detecting elements, the world's
smallest detecting element used for a clinical PET system (as of
September 2014), the system offers higher resolution for viewing
detailed drug distributions. Furthermore, uniform voxel size
spacing in the three orthogonal cross-section images provides
uniform high resolution images within the field of view. The ability
to acquire images in the prone position, which is less affected by
body movement due to breathing, is another reason sharp images
can be obtained.

DOI DetectorConventional Detector
DOI detectors are able to determine the depth in the scintillator where gamma rays are detected.
With conventional detectors, resolution is the highest at the center of the field of view and decreases the closer it is to the edge, where quantitative values are underestimated.With DOI detectors, resolution is maintained throughout the detector, so that quantitative ability is ensured all the way to the edges.
*1 DOI (depth of interaction) technology: Technology that can determine the depth inside the detecting element where radiation was detected, used to provide both high sensitivity and high resolution.
*2 Partial volume effect: Phenomenon where the smaller the object being imaged, the more the true size and PET image values are underestimated.
*3 SUV (standardized uptake value): A simple index for expressing the intensity of FDG accumulations in a tumor. In general, a high SUV value indicates high malignancy. The SUV is calculated by the following formula: PET image (radioactivity concentration of tumor)/(radioactivity dose/body weight).
