The head unit comprises a head unit case, an integrated light source, an image sensor, a wireless transceiver, a central processing unit, and a user-input component. The head unit case has an external surface defining an external cavity, an internal surface defining an internal cavity, a first aperture, and a second aperture. The integrated light source, the image sensor, the wireless transceiver, and the central processing unit are disposed within the internal cavity. The integrated light source extends from within the internal cavity into the first aperture and is configured to transmit light from the head unit through the first aperture. The image sensor is configured to detect an image transmitted into the head unit through the second aperture. The external cavity is configured to receive an external battery. The user-input component is disposed on the external surface. ## Claims ### Claim at position 1 1-36. (canceled) ### Claim 37 A wireless medical imaging system comprising a head unit, the head unit comprising: (i) a head unit case; (ii) an integrated light source; (iii) an image sensor; (iv) a wireless transceiver; (v) a central processing unit; and (vi) a user-input component; wherein: the head unit case has an external surface defining an external cavity, an internal surface defining an internal cavity, a first aperture, and a second aperture; the integrated light source, the image sensor, the wireless transceiver, and the central processing unit are disposed within the internal cavity; the integrated light source extends from within the internal cavity into the first aperture and is configured to transmit light from the head unit through the first aperture, wherein the integrated light source comprises: an emissive radiation source having a first spectrum; an optical element located to direct emissions from the emissive radiation source; a volumetric spectrum converter, the converter being located to convert emissions directed from the emissive radiation source to emissions having a second spectrum different from the first spectrum; an optical reflector located about the converter; and an output filter, the reflector being located to reflect the converter emissions towards the output filter; wherein the internal cavity of the head unit case contains the emissive radiation source, the optical element, the converter, the reflector, and the filter, and wherein desired light radiates from the internal cavity through the filter; the image sensor is configured to detect an image transmitted into the head unit through the second aperture; the external cavity is configured to receive an external battery; and the user-input component is disposed on the external surface. ### Claim 38 (depends on 37) The wireless medical imaging system according to claim 37, wherein the emissive radiation source operates in the range of 400 nm to 480 nm. ### Claim 39 (depends on 37) The wireless medical imaging system according to claim 37, wherein the optical element may either collimate, convergently focus, or divergently focus the emissive radiation source emissions onto the converter. ### Claim 40 (depends on 37) The wireless medical imaging system according to claim 37, wherein the optical reflector redirects omnidirectional light into a desired optical path. ### Claim 41 (depends on 37) The wireless medical imaging system according to claim 37, wherein the converter converts the emissions from the emissive radiation source to emissions of different wavelength, a narrower spectrum, or a broader spectrum, of non-coherent radiation. ### Claim 42 (depends on 37) The wireless medical imaging system according to claim 37, wherein the filter eliminates an emission from the emissive radiation source that has not been converted by the converter as well as optionally further conditioning the emitted light. ### Claim 43 (depends on 37) The wireless medical imaging system according to claim 37, wherein the emissive geometry of the emitted radiation spectrum from the integrated light source may be further conditioned, directed, focused, collimated, reflected, refracted, diffracted, or otherwise modified with the inclusion of suitable optical components. ### Claim 44 A wireless medical imaging system comprising a head unit comprising: (i) a head unit case; (ii) an integrated light source; (iii) an image sensor; (iv) a wireless transceiver; (v) a central processing unit; and (vi) a user-input component; wherein: the head unit case has an external surface defining an external cavity, an internal surface defining an internal cavity, a first aperture, and a second aperture; the integrated light source, the image sensor, the wireless transceiver, and the central processing unit are disposed within the internal cavity; the integrated light source extends from within the internal cavity into the first aperture and is configured to transmit light from the head unit through the first aperture; the image sensor is configured to detect an image transmitted into the head unit through the second aperture; the external cavity is configured to receive an external battery; and the user-input component is disposed on the external surface; and an external battery that is disposed in the external cavity and that provides power to one or more of the integrated light source, the image sensor, the wireless transceiver, or the central processing unit, wherein the external battery is a non-removable rechargeable battery.
