The invention relates to sensing compositional information about material by measuring thermal properties of the material. In one arrangement there is provided a needle probe for sensing compositional information. The probe comprises a needle having a tip region. A resistive element is attached to the needle at the tip region. A measurement system is configured to: 1) drive an electrical current through the resistive element to apply heating to the resistive element, and 2) measure an electrical response of the resistive element to the heating. A processing unit analyses the measured electrical response of the resistive element to the heating to determine compositional information about material in contact with the tip region.

An optical detection apparatus is arranged to detect particles in a fluid flowing through a tubing portion of transparent or translucent material. The apparatus comprises a holder for the tubing portion; a light emitting device configured to irradiate a target volume inside the tubing portion when arranged in the holder; and at least one light receiving device configured to receive light from the target volume when irradiated by the light emitting device and generate one or more time-dependent output signals indicative of the received light. A computation device is configured to determine a parameter indicative of temporal variability in the one or more time-dependent output signals and estimate the density based on the parameter, which has been found to be robust to structural differences between tubings and allows the apparatus to be deployed without calibration.

Systems, devices, and methods for identifying a target in a body using a spectroscopic feedback from the target are disclosed. An exemplary surgical feedback control system comprises a feedback analyzer configured to receive a reflected signal from a target in response to electromagnetic radiation directed at a target, and a controller in operative communication with the feedback analyzer. The controller can generate a control signal to a surgical system to perform a predetermined operation based upon the received reflected signal, including determining a composition of the target, or programming a laser setting to direct laser energy to the target.

Systems and methods for treating a mental health disorder using a psychoactive treatment protocol are described herein. A protocol dosage of the psychoactive chemical such as ketamine may be determined for a patient. A diminished dosage of the psychoactive chemical may be determined for the patient. A dosage progression may be determined based on the diminished dosage and a target dosage. The psychoactive chemical may be administered to the patient according to the dosage progression over a series of therapy sessions. The psychoactive chemical may be administered by intramuscular injection.

Aspects of the present disclosure are presented for a surgical instrument having one or more sensors at or a near an end effector and configured to aide in the detection of tissues and other materials and structures at a surgical site. The detections may then be used to aide in the placement of the end effector and to confirm which objects to operate on, or alternatively, to avoid. Examples of sensors include laser sensors used to employ Doppler shift principles to detect movement of objects at the surgical site, such as blood cells; resistance sensors to detect the presence of metal; monochromatic light sources that allow for different levels of absorption from different types of substances present at the surgical site, and near infrared spectrometers with small form factors.

A parenteral nutritional diagnostic system, apparatus, and method are disclosed. In an example, a parenteral nutritional diagnostic apparatus determines muscle quantity and muscle quality of a patient's psoas muscle to determine a nutritional status of the patient. An image interface is configured to receive a medical image including radiodensity data related to imaged tissue of the patient. The apparatus also includes a processor configured to use the medical image to determine a tissue surface area for each different value of radiodensity and determine a distribution of the tissue surface area for each radiodensity value. The processor is configured to determine muscle quality by locating a soft tissue peak within the distribution that corresponds to a local peak in at a region related to at least one of muscle tissue, organ tissue, and intramuscular adipose tissue. The processor determines the nutritional status of the patient based on the soft tissue peak.

A console for medical diagnosis includes a chair, a computer for displaying and communicating test results, various testing areas for performing multiple diagnostic tests, various testing devices including at least an EEG testing device, an ECG testing device, a BMD testing device, an ultrasonography testing device, and an EMG testing device, and openings for kidney probes and an echocardiogram probe. The testing areas include a first area for performing diagnostic tests on the head, a second area for performing diagnostic tests on sensory, a third area for performing diagnostic tests on the chest region, a fourth area for performing diagnostic tests on the pelvic and chest regions, a fifth area for performing diagnostic tests on blood, tissue, and bodily fluids, a sixth area for performing electromyographical tests, a seventh area for performing bone-related diagnostic tests, and an eighth area for performing diagnostic tests related to physical parameters and vitals.

Systems and methods for non-invasive fat reduction can include targeting a region of interest below a surface of skin, which contains fat and delivering ultrasound energy to the region of interest. The ultrasound energy generates a thermal lesion with said ultrasound energy on a fat cell. The lesion can create an opening in the surface of the fat cell, which allows the draining of a fluid out of the fat cell and through the opening. In addition, by applying ultrasound energy to fat cells to increase the temperature to between 43 degrees and 49 degrees, cell apoptosis can be realized, thereby resulting in reduction of fat.
