摘要:

AbstractA new technique which records color coded frequency information in B‐scan ultrasonography is described. The frequency spectrum of a wide band transducer (6MHz‐12MHz) is divided into three component bands each recorded as one of the three primary colors of light. The results of tissue model studies are presen

摘要:

AbstractThe need for increased dynamic range of echoes in ultrasonograms is generally acknowledged. Advantages and disadvantages of color‐coded gray scale ultrasonography as well as methods for their acquisition are discussed. A color encoding method for obtaining color ultrasonograms is described and results are demonstrate

摘要:

AbstractResults of preliminary clinical trials of spectra‐color ultrasonography are presented. The instrumentation is calibrated so that normal ocular tissues produce a near‐white display. Scans of eyes with various diseases differ from the scans of normal eyes, indicating a variation in frequency respon

摘要:

AbstractThe development and early clinical results of a real‐time color B‐scan ultrasonoscope are described. This instrument uses color to display detailed echo amplitude information more quantitatively than is possible with gray scale. With real time, dynamic changes are seen during the examination. Conversion of the amplitude information into binary coded decimal code permits separation into ten color steps and also eliminates “blooming” of the cathode ray tube, as seen in black and white. Integrated circuitry is used, providing a portable, relatively inexpensive unit. Early clinical work in ophthalmology is illu

摘要:

AbstractCompound scanning shows the size, shape, position, and anatomical relationships between the various organs in the upper abdomen. Gray scale compound scanning gives additional information from the parenchyma of organs and allows description of the characteristic ultrasonic appearance of specific tissues such as liver, spleen, or kidney. The method is complementary to simple scanning and for diagnostic work a combination of the two methods is recommended.

摘要:

AbstractA technique has been developed for the A‐mode display of the upper brain stem using certain bony landmarks to guide transducer placement. Normal findings were substantiated at the time of penumoencephalography and angiography in order to determine the anatomic origin of the ultrasound reflections. Findings in patients with mass lesions distorting the upper brain stem will also be reporte

摘要:

AbstractPreliminary results are presented of ultrasound investigations in 34 patients with suspected abdominal hernias. All patients were explored surgically on the basis of clinical indications, and the surgical findings were compared with the results of the ultrasound investigation. Small hernias in the anterior abdominal wall (fascia Spigelii and linea alba) can be demonstrated by ultrasound, but there are certain circumstances which can lead to false positive ultrasound results.
