“…The final segmentation step was based on the active contour model designed by Chan and Vese [ 65 ]. The evaluation step considered two data sources: a commercial high-frequency ultrasound imager HI VISION Preirus, Hitachi (Tokyo, Japan [ 36 ]), with 5–18 MHz EUP-L75 transducer and a custom system based on a manually scanning single-element transducer (V317, Olympus, (Tokyo, Japan)) [ 39 , 109 ], which included 60 images. The dataset was divided into 40 images used for parameter adjustment and 20 for validation.…”

Over the last few decades, computer-aided diagnosis systems have become a part of clinical practice. They have the potential to assist clinicians in daily diagnostic tasks. The image processing techniques are fast, repeatable, and robust, which helps physicians to detect, classify, segment, and measure various structures. The recent rapid development of computer methods for high-frequency ultrasound image analysis opens up new diagnostic paths in dermatology, allergology, cosmetology, and aesthetic medicine. This paper, being the first in this area, presents a research overview of high-frequency ultrasound image processing techniques, which have the potential to be a part of computer-aided diagnosis systems. The reviewed methods are categorized concerning the application, utilized ultrasound device, and image data-processing type. We present the bridge between diagnostic needs and already developed solutions and discuss their limitations and future directions in high-frequency ultrasound image analysis. A search was conducted of the technical literature from 2005 to September 2022, and in total, 31 studies describing image processing methods were reviewed. The quantitative and qualitative analysis included 39 algorithms, which were selected as the most effective in this field. They were completed by 20 medical papers and define the needs and opportunities for high-frequency ultrasound application and CAD development.

ObjectivesA compact handheld skin ultrasound imaging device has been developed that uses co-registered optical and ultrasound imaging to provide diagnostic information about the full skin depth and lesions encountered therein. The aim of the current work is to present the first clinical results of the device. Using additional photographic, dermoscopic and ultrasonic images as reference, the images from the device are assessed in terms of the detectability of the skin layer boundaries (between the epidermis, dermis, and subcutis), and in terms of image features produced by common skin lesions.MethodsCombined optical-ultrasonic recordings of various types of common skin lesions (melanoma, basal cell carcinoma, keratosis, dermatofibroma, naevus, dermatitis, psoriasis) were taken with the device (N = 53) and compared with images from a reference portable skin ultrasound imager. The investigator and two additional independent experts evaluated and compared the images in terms of skin structure detectability and skin lesion features.ResultsSkin structure detectability was unanimously over 90 % for epidermis, dermis and lesion. Morphological and echogenicity information observed for melanoma, basal cell carcinoma, keratoses, dermatofibroma, naevi, atopic dermatitis, psoriasis were found consistent with those of the reference ultrasound device and relevant ultrasound images in the literature.ConclusionsThe presented device is able to obtain simultaneous in-vivo optical and ultrasound images of common skin lesions. This has the potential to provide relevant information in a number of settings to be investigated in the future, including preoperative planning of skin cancer treatment.

“…Given the workload on the centers, which may have month-long waiting times [ 23 ], it would be useful if dermal ultrasound technology were more widely available. It is essential for the above aim to reduce the cost, increase portability, and improve and extend the interpretability of the images for non-radiologist users of skin ultrasound imaging devices [ 24 ].…”

A compact handheld skin ultrasound imaging device has been developed that uses co-registered optical and ultrasound imaging to provide diagnostic information about the full skin depth. The aim of the current work is to present the preliminary clinical results of this device. Using additional photographic, dermoscopic and ultrasonic images as reference, the images from the device were assessed in terms of the detectability of the main skin layer boundaries and characteristic image features. Combined optical-ultrasonic recordings of various types of skin lesions (melanoma, basal cell carcinoma, seborrheic keratosis, dermatofibroma, naevus, dermatitis and psoriasis) were taken with the device (N = 53) and compared with images captured with a reference portable skin ultrasound imager. The investigator and two additional independent experts performed the evaluation. The detectability of skin structures was over 90% for the epidermis, the dermis and the lesions. The morphological and echogenicity information observed for the different skin lesions were found consistent with those of the reference ultrasound device and relevant ultrasound images in the literature. The presented device was able to obtain simultaneous in-vivo optical and ultrasound images of various skin lesions. This has the potential for further investigations, including the preoperative planning of skin cancer treatment.
