###### Abstract
The subject of interest of the authors of this paper is the possibility of 3D breast ultrasound examination using an especially designed, universal, relatively easy to manufacture, and inexpensive device that would work with any conventional ultrasound B-mode scanner. Currently, 3D automated breast ultrasound represents an innovative technology that has received FDA (Food and Drug Administration) approval for the screening or early detection of breast cancer in the United States, particularly in women with dense glandular tissue [9]. Manufacturers already offer several certified 3D supine automated ultrasound (SAUS) systems of the breast on the market, as follows: 3D automated breast ultrasound (LOGIQ, Invenia ABUS, somo-v ABUS-trademark of the General Electric Healthcare company) and 3D automated breast volume scanning (ACUSON S2000 ABVS trademark of Siemens company, SOFIA trademark of Hitachi). ABUS systems are available in the following two designs, due to the way the breast is scanned: supine (women lie on the back) [9; 10] and prone (women lie on the abdomen) [11; 12]. The latest devices for ABUS in supine patient position consist of an articulated arm with a long array of ultrasonic transducers, a touchscreen monitor, and a dedicated workstation for image interpretation. Transducers are automatically adjusted to an operating frequency of approximately 5-15 MHz, depending on the selected depth (range) of breast tissue scanning. Once the ultrasound probe is placed on the breast, the breast tissue is scanned in an inferior (from the direction of the legs) to a superior direction (toward the head) to obtain an image. The ultrasound probe used in ABUS systems is approximately 15 cm long [13]. In comparison, the high-resolution ultrasound probe used for scanning in conventional B-mode HHUS scanners is much shorter (approximately 6 cm). The advantage of using a long transducer array is the ability to obtain a wide imaging field, which allows the visualization of a much wider range of breast tissue during a single scanning motion. The resulting 3D datasets contain hundreds of images per acquisition in \(\sim\)2 mm slices, without overlap. The technical advancement of ABUS systems lies in the use of special software that enables optimized image quality with high resolution and uniformity through advanced reconstruction algorithms and auto-adjustment of settings, such as frequency, gain compensation, and speckle reduction [14]. The diagnostic approach in the ABUS in prone patient position is different [11]. In this case, the breast is compressed by the patient's body weight. The bed has a small recess in which a linear ultrasound probe, about 10 cm long, is placed beneath. The probe is under a glass layer, on which ultrasound gel is applied. The woman is placed so that the breast fills the cavity. Thus, the breast changes shape and flattens when it touches the recess walls and their glass base, which are covered with the ultrasound gel. Automatic breast scan is activated by the touch screen monitor when the patient is placed properly with the nipple in the center of the bed recess. The ultrasound probe rotates clockwise around an axis passing near the extreme end of its length until a full 360\({}^{\circ}\) breast scan is completed. During the full rotation of the probe, the entire breast volume is scanned in less than a minute. It is possible to reach into the breast tissue to a depth of 6 cm. After scanning is complete, 3D images are reconstructed and can be visualized in all planes (e.g., sagittal, transverse, coronal, and radial). ABUS (or ABVS), compared to HHUS, is still under clinical investigation for the detection and characterization of breast cancer lesions, diagnostic efficacy, sensitivity, and specificity [15; 16]. There are studies available in the literature on a relatively small number of patients that show similar results in terms of the sensitivity and specificity of ABUS compared to HHUS [17; 18; 19; 20]. The results of the comparative study between MRI, HHUS, and ABVS presented by [PERSON] et al.
