“…The Moire phenomenon is a result of interaction between two periodic structures [ 18 , 19 ]. It has been widely used in a number of studies evaluating posture in children and adults [ 20 , 21 ].An important advantage of this method is that photogrammetric evaluation is a non-invasive test which can be repeated many times without putting patient’s health at risk [ 22 , 23 ].This technique has also been used in previous studies to evaluate the posture of women treated for breast cancer [ 7 , 8 , 11 , 12 ].…”

Purpose: The aim of the study was to evaluate posture in patients undergoing breast-conserving therapy (BCT) in relation to the type of surgical intervention to the axilla. Methods: The study was conducted on patients who had undergone breast-conserving surgical treatment for breast cancer 5–6 years earlier. In 54 patients, BCT+ALND (axillary lymph node dissection) was performed, while 63 patients were subjected to BCT+SLND (sentinel lymph node dissection). The control group consisted of 54 females. The study was conducted using digital postural assessment. Results: No statistically significant differences were observed with respect to the parameters between the BCT+SLNB and BCT+ALND groups (p > 0.05). However, the differences were highly significant between the CG (control group) and the studied groups (BCT+ALND, BCT+SLNB) for the following parameters: BETA angle of thoracolumbar spine inclination (p = 0.002), GAMMA angle of thoracic spine inclination (p = 0.0044), TKA (thoracic kyphosis angle) (p < 0.0001) and shoulder level inclination (p = 0.0004). The BCT+ALND patients were characterized by higher dependency of raised shoulder (p = 0.0028) and inferior angle of the scapula (p = 0.00018) on the operated side compared to BCT+SLNB patients. Conclusions: Postural imbalance occurs independent of the type of axillary intervention. Disturbances within the upper torso (abnormal position of shoulders and inferior angles of scapulae) are more pronounced in patients after ALND.

“…The axis of the observer encloses a certain angle with the axis of the projection by intersecting each other on the surface. [14][15][16] Several points can be found on the Moiré pattern what have the same distance from the reference surface (or base plane). By connecting these points, contours can be created, just like at the topographical maps, in this way the test surface can be described with these lines.…”

By the superimposition of two similar periodic structures translated, or rotated relative to each other, a new structure arises with longer periods. This one is called Moiré pattern and it consists of the Moiré fringes. Moiré imaging (used mostly in spinal deformities) is non-contact, fast, and its harmful radiation does not load patients and can be repeated any number of times. For detecting the spinals shape, a software has been implemented in LabVIEW programming environment with several image processing method. The shape of the spine could be sufficiently reproduced using this program. Screening can be established without X-Ray images, which is much faster and healthier for patients.

“…In practical applications, the examined specimen is positioned in front of a grating that is illuminated. The shadow of the grating is projected on the surface of the specimen [16].…”

In case of screening and tracking conditions of patients [20] with spinal deformities it is very important to develop an examination method that does not load patinets’ body with harmful radiation. This method is based on the moiré effect. Pictures were taken from patients’ back and information could be obtained about the back’s condition. A computer algorithm is under development that can produce the sagittal line of the spine from moiré images. This program is being tested with Scheuermann disease patients.
