The ENT department diagnoses and treats children and adults with ear, nose and throat diseases, with basic and highly specialised care. In such operations, a mixture of blood, water and bone fragments tends to create a lot of reflections in the image, so very high picture qual- ity is necessary. The ENT department needed to record each operation in high quality video for advanced research activities. ‘Ikegami’s MKC- 700HD high-end medical grade camera could deliver clear images even with different combinations of objects, colours and reflections,’ the company reports. ‘This was achieved by setting each parameter optimally. Our MLW-2623C high quality medi- cal grade monitor makes it possible to reproduce the image in full 1920 x 1080 high-definition. The MDR- 600HD records in full HD resolution during each operation.’ ‘This is a perfect camera for this type of application,’ confirmed Lennart Edfeldt MD PhD, at the Oto surgery/ENT department. ‘We are very pleased with the colour repro- duction, sharpness and especially the ability to reduce reflections in critical phases. The company’s MLW-2623C monitor has a high level of bright- ness, high resolution and a wide viewing angle. It also provides a high level of continuity in image qual- ity. The Ikegami MDR-600HD allows us to record images and photos in crystal clear high-definition via an intuitive front control panel. It should prove very useful for research work after each operation.’ The firm’s MKC-700HD high-end medical grade camera employs a 3-CMOS sensor to achieve full high- definition 1920 x 1080 pixel resolu- tion images. Sensitivity is approxi- mately 40% higher than on the standard model and it can perform better even at the low illumina- tion surgery, the company reports. ‘Optimised signal processing circuitry delivers a high signal-to-noise ratio of 54 dB.’ The MLW-2623C medical grade monitor employs a full high-defini- tion 1920 x 1080 pixel resolution panel for displaying extremely fine images, the firm adds. ‘Images can be viewed comfortably from almost any angle. The LCD panel has a high response speed to ensure minimal after-imaging. 10-bit signal process- ing ensures smooth image gradation. A high quality internal processor converts interlaced source signals into natural-looking progressive-scan Ikegami MKC-700HD 3-CMOS camera, 26 inch LCD video displays and full HD recording unit being tested in the ENT operating room at Uppsala Ikegami MLW-262 at Uppsala Unive New ultrasound applications are being investigated in areas such as capacitive micro-machined ultrasonic transducers for 3-D imaging, unique- geometry transducers, elastography and photo-acoustics. 2-D arrays for 3-D imaging can display details never seen before and bring earlier diagno- sis for tissue characterisation of the breast, prostate or liver, for example. Elastography can measure tissue stiffness and open up new diagnos- tic possibilities. The photoacoustic ultrasound modality can visualise the internal structures and functions of soft tissues with applicability in areas such as breast cancer screening and vascular disease assessment. Shear-wave elastography imaging is a technique with vast potential for medical diagnosis due to its higher contrast properties compared to tra- ditional B-mode or harmonic imag- ing. After generating a push pulse, a shear-wave is created in the tis- sue area. Capturing the shear-wave with a large ultrasound matrix array, and then generating and processing volumetric data can lead to research breakthroughs and, eventually, new clinical diagnosis methods for many diseases. Clearly, R&D fol- lowed by eventual clinical adoption of new diagnostic tech- niques in fields such as these requires a high-channel-count (HCC) ultrasound sys- tem that can interface to large matrix arrays. C e p h a s o n i c s , based in Silicon Valley, California, provides a flexible, open embed- ded-ultrasound plat- form, the cQuest Griffin HCC system, available in configurations that scale from 512 to 4096 synchronised channels ‘… enabling unprecedented ultra- sound innovation that can be car- ried forward into OEM production,’ the company reports. ‘Other con- figuration options include 1:1 or 1:3 probe multiplexing, transmit-module options, multi-probe modules and encoder-interface modules.’ Clinical-quality imaging capability is a hallmark of all cQuest systems, the firm adds. ‘This is requisite when moving from experimental devices in the lab to diagnostic products used in clinics. ‘Incorporating advanced image-processing algorithms, the real-time, user-adjustable ultra- sound image-enhancement software enhances anatomic structures with simultaneous speckle reduction and includes filters optimised for anato- my-specific details of texture, scale and morphology.’ ‘The Cephasonics cQuest Ultrasound Software Development Kit (CUSDK) suite provides a fast way to develop ultrasound-based prod- ucts with pre-tuned configuration files and turnkey example applica- tions. An entire family of products can be easily realised since the soft- ware only needs to be written once. Flexible data processing with custom algorithm extensions is unique to Cephasonics. ‘Developers can select the optimal signal format for their use case, add proprietary signal-processing algo- rithms, and synergise with the clinical image-processing stack.’ The high channel count, open, embedded-ultrasound system Interfacing to large matrix arrays Cephasonics is at Medica Hall 16 / D40-1 M_TopLine_103x297.indd 123.10.1508:15 EH @ MEDICA No 12015
