Definitions
- the spectral separator can be a tunable filter, such as a liquid crystal tunable filter, and the imaging sensor can be a two-dimensional imaging array, such as a charge coupled device.
- the optic can include a macro lens, an adjustable lens, or a probe that includes an imaging fiber optic cable, and a stand can be connected relative to the optic to position the optic relative to the patient.
- the control interface can be operable to adjust the filter at least twenty times to acquire hyperspectral data for redisplay in real time.
- the medical instrument can perform diagnostic processing for images acquired exclusively under visible light.
- the general-purpose nature of the instrument can also help the surgeon develop significant amounts of medical information in time-critical surgical situations. For example, a patient may undergo relatively straight-forward surgery during which the surgeon may discover a tumor or another internal condition. With an instrument according to the invention, the physician can spend a small amount of additional time with the patient under anesthesia and determine the nature and extent of the tumor. This can be particularly beneficial during major surgery, where extending surgery duration poses a potential morbidity and mortality risk. Because the procedure is rapid and noninvasive, the patient is exposed to little additional risk. The benefit of immediate diagnosis and evaluation is significant.
- An instrument according to the invention may also be able to provide a wide variety of diagnostic capabilities, allowing a physician to enhance the capabilities of his or her practice substantially in a variety of different realms, without investing in a number of instruments.
- the physician can then enhance or update the instrument by the adding software modules that are specifically targeted towards certain conditions of particular tissues, subsystems, or disease states.
- This can allow a single base instrument to be configured for a variety of different types of practices, and priced according to the type of practice to be served by the instrument.
- a general-purpose instrument to be used by a general surgeon could include a package of diagnostic protocols that would permit the diagnosis of a variety of conditions that a general surgeon might encounter, while a neurosurgeon's module might be added to allow a specialist to detect particular conditions within the brain.
- Electronic and optical upgrades may also be provided to update, specialize, or improve the performance of the instrument. Such upgrades can include processing modules, memory boards, lenses, and the like.
