Zonare Medical Systems of Mountain View, CA, will introduce several new transducers for its z.one convertible ultrasound scanner at this year's meeting.
The P10-4 transducer is appropriate for neonatal, infant, and pediatric patients. An ergonomic design provides a comfortable grip for scanning through isolettes and tiny acoustic windows. The transducer supports as many as six frequencies, including harmonic imaging at 8 MHz (received), as well as two color Doppler frequencies and three B-mode frequencies.
Zonare's new P4-1 transducer was developed for small-footprint abdominal and ob/gyn sonography. The transducer uses a Hanafy lens design, which improves image uniformity by controlling the slice thickness of the ultrasound beam. A press of a button can change the transmitted frequency down to 2 MHz, and it can penetrate up to 30 cm.
The company will also show its new L7-4 vascular transducer, currently a work-in-progress. It has a lightweight ergonomic design and offers 16-cm penetration for difficult-to-image patients. The transducer has multiple frequencies, including color Doppler, harmonic, and B-mode variable frequencies.
Zonare will also add abdominal and venous calculation packages. Both new packages allow sonographers to use a protocol checklist with reports that includes organ sizes, Doppler results, and comments sections.

![Examples of ultrasound findings and techniques. (A) Images in a 39-year-old male patient with a mass in the left thigh. The mass is heterogeneous on the B-mode US image (compared with the patient in D) and showed increased microvascularity (superb microvascular imaging [SMI]) and shear-wave elastography (SWE) values. Undifferentiated pleomorphic sarcoma was diagnosed at biopsy (with pleomorphic rhabdomyosarcoma in surgical specimen). (B) Images in an 18-year-old male patient with a mass in the left leg. The mass is hypoechoic on the B-mode image, with no other findings suggestive of malignancy. The lesion is in contact with the cortex of the tibia, which is slightly irregular. CT revealed a doubtful anteromedial tibial erosion. The microvascular study demonstrated high vascularization, suggestive of malignancy. Periosteal Ewing sarcoma was diagnosed with both histologic and immunohistochemical confirmation. (C) Images in a 69-year-old female patient with a lump growing on the outside of the left leg. Multiple SWE examinations were performed (please note the high values obtained in the measurements, whereas the color map highlights the stiffness relative to adjacent tissues). SMI showed areas of increased vascularization to target for sampling. Undifferentiated spindle cell sarcoma was diagnosed at biopsy, with residual leiomyosarcoma in the surgical specimen after neoadjuvant therapy. (D) Images in a 56-year-old female patient with a mass in the right thigh. The mass is heterogeneous at both B-mode ultrasound (similar to patient A) and MRI (coronal T2-weighted spectral attenuated inversion recovery [SPAIR]; T1-weighted pre-contrast and postcontrast imaging), which even shows uptake after the administration of paramagnetic contrast material, which is traditionally suggestive of malignancy. Low values at SMI and elastography are suggestive of benignity. Spindle cell lipoma was diagnosed at biopsy, with atypical spindle cell lipomatous tumor in the surgical specimen.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/08/images-radiol250278fig2.APCFLSvX6p.jpg?auto=format%2Ccompress&fit=crop&h=100&q=70&w=100)
