The treatment device comprises: an optical diffuser arranged on the treatment device such that an outer surface of the optical diffuser is proximate to, or in contact with, skin of the subject when the treatment device is to be used to perform the treatment operation; and an imaging unit for obtaining one or more images using light passing through the optical diffuser into the treatment device; wherein the treatment device is further configured for providing one or more images to a processing unit for determination of whether the treatment device is in contact with the skin.

One or more devices, systems, and methods are described which together provide sonoluminescence biophysical oscillation technique(s) (SBOT(s)) that improve debilitated states of health for individuals comprising; biophysical oscillations that initiate, sustain, and/or control one or more sound emitting devices including speakers capable of providing harmonic and subharmonic sound and including music and/or individual musical notes that provide sound tracsons and one or more light emission devices including projectors that provide light wave emission traclums which are capable of imparting color changes, wherein tracsons and traclums provide auditory and visual stimuli that result in energy changes that create acoustic and tracson/traclum excitations. The tracson/traclum excitations are applied in an external manner to one or more bodies of humans and in some cases could be applied to animals.

According to an aspect, there is provided an apparatus for use with a treatment device for providing feedback to a user on a treatment operation performed on a body part of a subject, wherein the treatment device is configured to apply light pulses to skin of the body part to perform the treatment operation, wherein a light pulse applied to the skin treats an area of the skin. The apparatus comprises a processing unit configured to receive a first measurement signal from a first sensor, the first measurement signal comprising information about positions and/or movements of the treatment device over time; for a light pulse previously applied by the treatment device to the body part during the treatment operation, process the first measurement signal to estimate a previous treatment position as a position of the treatment device relative to the body part when the light pulse was generated; for the previously applied light pulse and based on the estimated previous treatment position, estimate a previous treatment area for the light pulse corresponding to the area of skin of the body part that the light pulse was applied to when the treatment device was at the previous treatment position; process the first measurement signal to estimate a current position of the treatment device relative to the body part; based on the estimated current position of the treatment device, estimate a current treatment area corresponding to an area of skin that the treatment device would apply a light pulse to while in the current position; and generate a feedback control signal for a feedback unit, wherein the feedback control signal is configured to cause the feedback unit to generate feedback indicating whether the current treatment area corresponds, or substantially corresponds, to a previous treatment area.
