Photonics Medical Application Notes

  1. Medical X-Ray Imaging System Improves Patient Diagnosis 8/20/2010
    For more than 40 years, Italray srl has been a manufacturer of radiological equipment for traditional and digital medical applications, and of computer-assisted systems dedicated to radiological purposes. In recent years, Italray’s laboratories have developed the X-Frame line of digital imaging systems, which includes the X-Frame CCD series for radiology/fluoroscopy applications. With the help of image acquisition boards and software from DALSA, X-Frame CCD systems provide the high-speed image acquisition, real-time data processing and storage capabilities, and image reliability needed to address the challenges of the applications for which the systems were developed.
  2. Single Photon Counting With A Focus On Biomedical Applications 3/22/2011

    Over the past few years a growing number of companies have come to rely on Photon Counting for applications that range from particle sizing, atmospheric studies and advanced forms of biomedical research. By Excelitas Technologies

  3. Application Note: Nonlinear Microscopy 9/16/2008
    Ultrafast lasers have revolutionized the field of microscopy by enabling new types of nonlinear microscopy techniques. Femtosecond pulse lasers provide the combination of high peak power (1-100 kW) and low average power (10-1000mW) which is ideal for utilizing nonlinear optical processes in scanning laser microscopy (LSM). Here, we describe the two main varieties of nonlinear microscopy: two-photon microscopy, and third-harmonic generation (THG) microscopy. And we show images using these techniques with various types of modelocked fiber lasers. By IMRA America, Inc.
  4. Coherent Anti-Stokes Raman Scattering Imaging: A Basic Overview With An Emphasis On The Optics Required 5/11/2012

    Coherent anti-­Stokes Raman scattering (CARS) imaging is a nonlinear optical technique that captures intrinsic molecular vibrations to create optical contrast. It offers submicron level spatial resolution and video-­speed imaging rate without the needs for extrinsic labels. In a CARS process, a pump laser, a Stokes laser and a probe laser (usually same as the Pump laser) are involved.

  7. Advantages of Point Source Emitters: Application Note 4/30/2012

    A Point Source Emitter is similar to a standard LED, however, its well defined circular area (usually 25μm-200μm in diameter) makes it ideal in applications involving encoders, machine vision, medical fiber, and any other application where a precise beam of light is needed. This application note provides background information on Point Source Emitters, and highlights their advantages over standard LEDs.

  8. Technical Note: High-Precision Micromachining 9/16/2008
    Laser micromachining is a large and rapidly-growing application area for pulsed lasers. In fact, the general application area of materials processing forms the largest single application market for all lasers sold. Microelectronics in particular is one of the largest industry sectors that uses laser micromachining for a variety of applications including mask repair, chip repair, linkblowing, wafer processing, via-hole drilling and others. Pulsed lasers that are widely used include excimer lasers and Qswitched solid-state lasers such as Nd:YAG and Vanadate systems. By IMRA America, Inc.
  9. Application Note: Scintillator Readout With SPM 8/18/2008
    A large number of radiation detection applications utilize scintillation crystals to convert gammaor X-rays into a burst of optical photons that can then be measured with a suitable photodetector. Depending on the scintillator type and the application, the photodetector could be a PMT, PIN diode or an APD. The SPM is considered to be a viable alternative to these options, giving performance comparable with a PMT in the small, rugged, low voltage format of a PIN or APD.
  10. Flexible Fluorescence Technical Tip 1/22/2013

    Fluorescence is one of the most beautiful phenomena in nature, as fascinating to us today as it was for early scientists. It occurs throughout nature: gemstones, minerals, chlorophyll and even crude oil residues fluoresce. And though fluorescence began as a field of scientific study, it has evolved and matured into a technique that now enables entire fields of cutting-edge science and medicine.
