Photonics Medical Application Notes

1. Application Note: Magnetic Field Sensitivity 8/18/2008
   SPM detectors are insensitive to magnetic fields unlike PMTs, which are very sensitive to even weak magnetic fields (<0.1T).
2. Optical Coherence Tomography 9/26/2022

   Optical coherence tomography (OCT) is a noninvasive, high-resolution optical imaging technology that creates cross-sectional images from interference signals received from an object under investigation and a local reference.

3. The Evaluation Of Increase And Distribution Of Temperature During The Dental Drilling Using A Thermal Imaging Camera 2/17/2012

   This paper discusses the use of infrared technology to study the optimal method for post space preparation of teeth including how long to drill, the type and size of dental drill used, and the type of cooling used.

4. Pre-, Intra-, And Postoperative Use Of Dynamic Infrared Thermography (DIRT) Provides Valuable Information On Skin Perfusion In Perforator Flaps Used In Reconstructive Surgery 2/17/2012

   A study of dynamic infrared thermography (DIRT) in all three phases of perforator flap surgery.

5. 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.
6. Lenses For Diagnostics 10/13/2023

   Medical diagnostics rely heavily on imaging technologies that allow physicians to examine and assess a patient's body structures and functions in great detail.

7. 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.
8. Application Note: Detection Of Hydrocarbon Radicals During Plasma Etching 4/16/2010

   Optical emission spectroscopy is used to study and monitor the plasma etching of hydrogenated amorphous carbon (a-C:H) thin films. T.A.R. Hansen and R. Engeln, Eindhoven University of Technology

9. Using Raman Spectroscopy To Detect Malignant Changes In Tissues 5/25/2012

   Accurate, rapid, and non-invasive detection and diagnosis of malignant disease in tissues is an important goal of biomedical research. Optical methods, such as diffuse reflectance, fluorescence spectroscopy, and Raman spectroscopy, have all been investigated as ways to attain this goal. Diffuse reflectance utilizes the absorption and scattering properties of tissues, particularly from cell nuclei and stroma.

10. OCT for Non-Destructive Testing 12/18/2012

    Optical Coherence Tomography (OCT) is an imaging method that scans light across a sample/object, and then processes and transforms the reflected light to create a depth profile of up to several mm. Tornado Spectral Systems has developed a nanophotonic spectrometer for use in this application space.
