“…The earliest 3D transducers combined linear multielement arrays for two of the dimensions, with a mechanical (or manual) scan for the third dimension, allowing a volume of image data to be captured for processing. [31][32][33][34] This volume data set is the collection of the 2D images organized in the third dimension much like the pages in a book (Figure 2). Manual freehand scanning in the third dimension can be used to create a 3D image, the result of which is sonographer dependent and qualitative.…”

Diagnostic medical ultrasound transducers have evolved through the years and have contributed significantly to improved patient care. This article discusses the history and types of transducers and the elements that have changed over time. There has been a sharp transition from natural to human-made elements and from one to many in a single transducer. Ergonomics also now plays a role in transducer design and will continue to do so; the grip, weight, and size of transducers are in the forefront of design considerations. The evolution of transducers has changed not only how well we visualize anatomy and what anatomy we see but also how the patient's care is managed. Different, new, and emerging technologies certainly will continue to be identified within the sonography community.

“…However, a recently introduced matrix array transducer has been reported to rapidly acquire static volume data sets that reduce volumetric errors evoked by respiratory or other motion artifacts. 15 Thus, we thought that 3D sonography with a matrix array transducer might offer a more accurate means of assessing organ volumes. To our knowledge, no report has been issued to date concerning the use of this technology for 3D sonographic renal volume measurement.…”

“…15,16 The transducer used in this study had 2400 elements for 360° focusing and steering, and it allowed static volume data to be acquired instantaneously, thus reducing 3D measurement errors produced by motion artifacts. Although the kidneys have no inherent motion, respiration-induced movements should be considered.…”

“…Acquisition of volume data sets using a 3D sonographic transducer can allow clinicians to measure the volumes of lesions such as cysts and tumors 15 ; thus, these units could be important for patient treatment and therapeutic planning for many conditions, such as abdominal aortic aneurysms, chronic renal diseases, and gallbladder dysfunctions. 15,23 A preliminary in vitro investigation found that volume measurements obtained by a 3D sonographic transducer reduced volume errors and interobserver variations.…”

Objective. The purpose of this study was to examine the feasibility of 3-dimensional (3D) sonography using a matrix array transducer to measure renal volume. Methods. One hundred consecutive patients with a normal serum creatinine level and kidney appearance on computed tomography (CT) performed within 2 months before sonography were enrolled in this study. Two hundred individual renal volumes were blindly obtained by the ellipsoid formula, the stacked ellipse method, the voxel count method using routine 2-dimensional (2D) sonographic data, 3D sonographic data using a matrix array transducer, and CT data, respectively. The voxel count method was validated as the reference standard by the water displacement method in 10 cadaveric pig kidneys (r = 0.99; P < .001). Renal volumes determined by 2D and 3D sonography were compared with volumes determined by CT. Results. Volumes determined by 2D sonography were significantly lower than those determined by CT (P < .001) but similar to those determined by 3D sonography (P = .78). The percent volume error of 3D sonography (mean ± SD, -2.2% ± 3.7%) was significantly lower than that of 2D sonography (-15.7% ± 11.8%) with CT as the standard (P < .001). The correlation coefficient between 3D sonography and CT (r = 0.98; P < .0001) was better than that between 2D sonography and CT (r = 0.83; P < .0001). In addition, Bland-Altman analysis revealed that the limits of agreement between 3D sonography and CT (-9.7% to 5.1%) were narrower than those between 2D sonography and CT (-45.6% to 9.8%). Conclusions. Three-dimensional sonography with a matrix array transducer can significantly reduce renal volume measurement errors and offers a reliable means of determining renal volumes.

Aims: Whether different diabetic kidney disease (DKD) phenotypes recognise differences in morphological and vascular properties of the kidney is still unexplored.We evaluated the potential role of kidney ultrasonography in differentiating DKD phenotypes in subjects with type 2 diabetes. Materials and Methods:This is a cross-sectional, single-centre study. Total (TRV) and parenchymal renal volumes (PRV) were calculated by applying the ellipsoid formula for conventional (2D) ultrasonography and with manual segmentation for 3D ultrasonography, and then adjusted for body surface area (aTRV, aPRV). Renal resistive index (RI) was contextually determined. DKD phenotypes have been defined based on increased urinary albumin-to-creatinine ratio (ACR >30 mg/g) and/or reduced eGFR (<60 ml/min/1.73 m 2 ). Recruitment was planned to have groups of the same size.Results: Among 256 subjects, 26.2% had No-DKD, 24.6% increased albuminuria only (Alb + ), 24.2% non-albuminuric DKD (Alb − DKD), and 25.0% albuminuric DKD
