TL;DR: In this article, a single transducer is configured such that when connected to the subsystems, the therapy subsystem can generate high power acoustic energy to heat the treatment region, and the temperature monitoring subsystem can map and monitor the temperature of the treatment regions and display the temperature on the display, all through the use of the single transducers.
Abstract: An ultrasonic system useful for providing imaging, therapy and temperature monitoring generally comprises an acoustic transducer assembly configured to enable the ultrasound system to perform the imaging, therapy and temperature monitoring functions. The acoustic transducer assembly comprises a single transducer that is operatively connected to an imaging subsystem, a therapy subsystem and a temperature monitoring subsystem. The ultrasound system may also include a display for imaging and temperature monitoring functions. An exemplary single transducer is configured such that when connected to the subsystems, the imaging subsystem can generate an image of a treatment region on the display, the therapy subsystem can generate high power acoustic energy to heat the treatment region, and the temperature monitoring subsystem can map and monitor the temperature of the treatment region and display the temperature on the display, all through the use of the single transducer. Additionally, the acoustic transducer assembly can be configured to provide three-dimensional imaging, temperature monitoring or therapeutic heating through the use of adaptive algorithms and/or rotational or translational movement. Moreover, a plurality of the exemplary single transducers can be provided to facilitate enhanced treatment capabilities.

TL;DR: In this article, a non-invasive visual imaging system is provided, wherein the imaging system procures an image of a transducer position during diagnostic or therapeutic treatment, such that the corresponding images represent not only the location of the transducers with respect to the patient, but also the ultrasonic image of the region of interest being scanned.
Abstract: A non-invasive visual imaging system is provided, wherein the imaging system procures an image of a transducer position during diagnostic or therapeutic treatment. In addition, the system suitably provides for the transducer to capture patient information, such as acoustic, temperature, or ultrasonic images. For example, an ultrasonic image captured by the transducer can be correlated, fused or otherwise combined with the corresponding positional transducer image, such that the corresponding images represent not only the location of the transducer with respect to the patient, but also the ultrasonic image of the region of interest being scanned. Further, a system is provided wherein the information relating to the transducer position on a single patient may be used to capture similar imaging planes on the same patient, or with subsequent patients. Moreover, the imaging information can be effectively utilized as a training tool for medical practitioners.

TL;DR: In this article, an expandable spinal implant (100) is made having movable parts (10, 20), that can arranged so as to have a small maximum cross-sectional width so that the cage can be inserted through a smaller surgical opening and then expanded to a full size assembly between the vertebrae.
Abstract: Multiple embodiments of the present invention provide methods and apparatuses for maintaining spacing between neighboring vertebrae, while minimizing the size of the surgical opening required. In one embodiment, an expandable spinal implant (100) is made having movable parts (10, 20), that can arranged so as to have a small maximum cross-sectional width so that the cage can be inserted through a smaller surgical opening and then expanded to a full size assembly between the vertebrae.

02 Jan 1973TL;DR: In this paper, an apparatus and method for recording images on recording mediums which images correspond to high energy radiation patterns was described, which can be used at any reproduction ratio, particularly usable in recording images representative of large format high energy patterns onto microfilm.
Abstract: The disclosure relates to an apparatus and method for recording images on recording mediums which images correspond to high energy radiation patterns. A temporary storage medium, such as an infrared-stimulable phosphor or thermoluminescent material, is exposed to an incident pattern of high energy radiation. A time interval after exposure, a small area beam of long wave length radiation or heat scans the screen to release the stored energy as light. An appropriate sensor receives the light emitted by the screen and produces electrical energy in accordance with the light received. The information carried by the electrical energy is transformed into a recorded image by scanning an information storage medium with a light beam which is intensity modulated in accordance with the electrical energy. Although the invention can be used at any reproduction ratio, it is particularly usable in recording images representative of large format high energy patterns onto microfilm.

TL;DR: In this article, a surface treatment method is appropriately selected from already known methods such as a dry direct treatment, according to the fluorescent body and the solvent to be used, and the sheet is placed on a carrier body.
Abstract: PURPOSE:To enable manufacturing a radiation image conversion panel having a high packing of a fluorescent body and a high sensitivity by applying a surface treatment to sitmulated phosphorescent particles in a fluorescent layer, by use of a coupling agent of a titanate series. CONSTITUTION:A coupling agent of a titanate series has a function to loosen aggregation by forming an organic monomolecular film on an inorganic surface, to distribute fluorescent particles homogeneously. As this sort of a coupling agent, it is preferable to use a light yellow liquid solvent such as a tetraoctyl bis (ditridecyl phosphite) titanate and the like. A surface treatment method is appropriately selected from already known methods such as a dry direct treatment, according to the fluorescent body and the solvent to be used. In this way, a fluorescent sheet consisting of a surface-treated fluorescent body and a binder is produced, and the sheet is placed on a carrier body. At the same time, the sheet is compressed at a temperature higher than a softening temperature or a melting point of the binder. This process can raise the packing of the fluorescent body while suppressing decrease of the sensitivity.
