“…However, the operator dependency and lack of standardization and reproducibility for HHUS are important limitations for its use. Automated whole breast ultrasonography (AWUS) has been proposed as a promising tool for overcoming disadvantages of HHUS [2][3][4][5] and has been developed during the last decades [6,7]. Recent advances in high-frequency broadband transducers, combined with volumetric technology, enables AWUS to compete with HHUS.…”

“…Other systems developed for ultrasound imaging of a compressed breast through a mammographic paddle have experienced limited success (Schütze et al 1998;Richter 1997;Richter 1995;Richter 1994;Moskalik et al 1995;Kelly-Fry and Jackson 1991). Some of the difficulties that these systems faced included highly attenuating compression paddles, substantial reverberations, low frequencies, weakly focused beams and image artifacts created by refractions through the paddles.…”

We are developing a combined digital mammography/3D ultrasound system to improve detection and/or characterization of breast lesions. Ultrasound scanning through a mammographic paddle could significantly reduce signal level, degrade beam focusing, and create reverberations. Thus, appropriate paddle choice is essential for accurate sonographic lesion detection and assessment with this system. In this study, we characterized ultrasound image quality through paddles of varying materials (lexan, polyurethane, TPX, mylar) and thicknesses (0.25-2.5 mm). Analytical experiments focused on lexan and TPX, which preliminary results demonstrated were most competitive. Spatial and contrast resolution, sidelobe and range lobe levels, contrast and signal strength were compared with no-paddle images. When the beamforming of the system was corrected to account for imaging through the paddle, the TPX 2.5 mm paddle performed the best. Test objects imaged through this paddle demonstrated ≤ 15% reduction in spatial resolution, ≤ 7.5 dB signal loss, ≤ 3 dB contrast loss, and range lobe levels ≥ 35 dB below signal maximum over 4 cm. TPX paddles < 2.5 mm could also be used with this system, depending on imaging goals. In 10 human subjects with cysts, small CNR losses were observed but were determined to be statistically insignificant. Radiologists concluded that 75% of cysts in through-paddle scans were at least as detectable as in their corresponding directcontact scans.

“…Die Sonographie muû von einem Arzt durchgeführt werden, aber es besteht keinerlei Strahlenbelastung. Die Reproduzierbarkeit durch ein automatisiertes Ultraschallsystem gelingt bisher nur mit einem in der klinischen Erprobung befindlichen Prototyp, wie es von unserer Arbeitsgruppe beschrieben wurde [23]. Verbesserungen durch derartige Neuerungen wie auch durch ein verbessertes Auflösungsvermögen und den Einsatz von Kontrastmitteln in der Sonographie werden vielleicht in der Zukunft andere Prioritäten setzen.…”

For the histological verification of suspicious non-palpable small breast tumors, the three-dimensional breast biopsy applied as cylindrical extirpation using the ABBI system is the optimal solution at present. Because of the possibility of performing mammography during the operation, errors of localization can be corrected and incorrect incisions avoided. Taking the three radiomorphologically leading symptoms into consideration--suspicious microcalcification, focal shadow and structural irregularity--it can be stated that the digital mammography of the ABBI system is more sensitive than the conventional one for detecting microcalcification, but focal shadow and structural irregularity are detected less well by digital technique. These structures should be preoperatively marked by using sonography. After the complete removal of suspicious microcalcification checked by digital mammography during the operation, residual tumor might be found in a second excision when histologically invasive or intraductal tumor terminations reach the excision margin (R1 resection). Thirteen invasive and 8 intraductal carcinomas were found in 80 cases of cylindrical extirpation using the ABBI system. In 7 procedures carried out to exclude an in-breast recurrence, 3 intraductal carcinomas and 1 invasive carcinoma were observed. In 8 of 12 invasive carcinomas and in 1 of 5 intraductal carcinomas, breast-conserving therapy was indicated. Two cases of invasive carcinoma fulfilled the criteria applied (minimal tumor-free margin > 2 mm, no extensive intraductal component) to use the ABBI cylinder as lumpectomy without a second excision to follow.
