Acclimatization; Matrix Selection; Examination - Braster In-home Breast Examination System User Manual

7.2.5. ACCLIMATIZATION

The next stage of the examination is a six-minute acclimatization, i.e. regulation and stabilization of breast skin temperature. To
do this, you will be required to undress from the waist up. Acclimatization is key if you want to obtain good quality thermographic
images during the examination. Only with a properly conducted acclimatization can you be sure that the results will be reliable.
To complete the acclimatization process, follow the instructions displayed on subsequent app screens.

7.2.6. MATRIX SELECTION

At this stage, you need to select the matrix for the examination. Your Braster device was provided with a set of three matrices.
Each of them works in a different range of temperatures. Remember that your body temperature depends on, among other
factors, the day of your menstrual cycle, your age and metabolism. In order to produce a high-resolution thermographic image
that will show the distribution of temperatures across your breasts, you will have to select a matrix before each examination.
To select a matrix, make one application of the Braster device to the central area of each breast. Make sure, that the whole
matrix adheres tightly to the body. The app will guide you step by step through this process.
First place matrix No. 2 on the device (the number of the matrix is stated on the plastic frame). Follow the instructions displayed
on subsequent screens.
! START THE MATRIX SELECTION WITH YOUR RIGHT BREAST.
When instructed apply the device centrally to your breast and press the grip (see. Fig. 3: to see the location of the grip). The
clicking sound means that the grip has been pressed correctly.
Remember to hold the grip down as long as the examination is in progress. Do not move the device across your breast, hold
it firmly in one place. When instructed, release the button and move the device away from your breast (see Fig. 6: device
application to the breast).
! REPEAT THESE STEPS FOR YOUR LEFT BREAST.
If matrix No. 2 is suitable for you, you can start the examination. If it does not suit you, you will be asked to remove matrix No. 2
and repeat the applications with matrix No. 1 or 3. You may be asked to return to matrix no. 2 if it is more suitable for the patient's
body temperature. Once the appropriate matrix has been selected, you can start the examination.

7.2.7. EXAMINATION

Before you start the examination, read the instructions displayed when you select "Examination" on the navigation screen.
From those instructions, you will learn exactly what to do during the examination and how to apply the device to your breasts.
To ensure top quality thermographic images during the examination:
• apply the device perpendicular to your breast (see Fig. 7: correctly applied device);
• do not lift your breast;
• do not move the device across your breast, instead hold it firmly in one place (see Fig. 8: improperly applied device);
• do not move the device away until instructed;
• keep the grip pressed as long as the examination is in progress;
• do not touch your breast with your hands during the examination.
Depending on the breast size which you entered in "My data" tab in your individual account on myaccount.braster.eu, you will
be required to make three or five applications to each breast.
ALWAYS BEGIN WITH YOUR RIGHT BREAST
This is very important, as the thermographic images of your breasts produced in individual examinations are compared to
one another. We compare the image(s) from current examination with images produced during your last five examinations.
By comparing images produced during the past examinations we can observe if there have been any changes in structural or
thermal asymmetry over time.
Breast size 1, 2 or 3
If your breast size is 1, 2 or 3, see Fig. 9A for size 1 or 2 and Fig. 9B for size 3. During the examination you will have to perform:
1) One central application to the breast, making sure that the lower edge of the matrix, i.e. the black part (the thermographic
foil), adheres to your breast (not your abdomen). Do not push your breast up.
