Disclosed are instruments and methods for acquiring co-registered orthogonal fluorescence and photoacoustic volumetric projections of an interrogated object. In an embodiment, an instrument includes a rotary mechanism configured to rotate an interrogated object relative to an array of photoacoustic transducers and an optical detector. An optical excitation unit is configured to irradiate the interrogated object with pulses of light, inducing both fluorescence and photoacoustic responses inside the interrogated object at each of a plurality of rotational positions. The array of photoacoustic transducers includes unfocused elements arranged in a pattern along an axis of rotation, the elements configured to detect photoacoustic signals generated inside the volume of the interrogated object. The optical detector is arranged opposite to the array of photoacoustic transducers with respect to the axis of rotation and is configured to register sources of fluorescence excited inside the interrogated object. Each of the optical excitation axes form with each of the optical detection axes, and with each of the photoacoustic detection axes, angles that are between 60 and 90 so as to enable acquisition of co-registered orthogonal fluorescence and photoacoustic volumetric projections of the interrogated object.

Described herein are systems and methods of processing immobilization molds for application of treatment, A computing system may generate a three-dimensional mold model of immobilization mold within with a subject is to be positioned for application of a treatment. The computing system may subtract a three-dimensional scan of at least a portion of the subject from the three-dimensional mold model to define an opening therein. The computing system may remove, from the three-dimensional mold model, a first portion to define an imprint in the opening from a first axis along which the subject is to enter. The computing system may remove, from a second portion of the three-dimensional mold model remaining with the removal of the first portion, inward protrusions into the imprint of relative to the second axis intersecting the first axis.

The present invention is a medical posture retainer having a mat and a core member. The mat includes an airtight bag and a cushion layer. The airtight bag is a cover of the mat and has a gas barrier property. An exhaust valve for deflation is attached to the bag. The cushion layer is formed of particles in the bag. The core member includes a plate-like support that is attached to a side face of the hag to keep a certain rise height, and a stopper that is attached to the upper face and the lower face of the airtight bag to restrict the rise height. The core member is attached before deflation of the bag so as to impart a shape necessary for receiving a specific part of a human body.

Certain aspects of the disclosure are directed to determining cardiac physiological parameters. Specific embodiments concern an arrangement of apparatuses including a platform region configured and arranged with an area for the user to stand, a plurality of force sensors including sensor circuitry, and a processor circuitry. The force sensors provide a plurality of analog signals while the user is standing on the platform region. The processor circuitry is configured and arranged to determine cardiac physiological parameters of the user corresponding to a graphical representation of cardiac movements, by processing the analog signals, mitigating at least some effect on the analog signals attributable to postural sway of the user, and generating data indicative of the physiological parameters based on said processing of the analog signals and the mitigating of at least some of the effect on the analog signals attributable to postural sway of the user.

A method for determining an item of patient information that alludes to a position and/or a movement of a patient during an examination and/or treatment process with a medical engineering apparatus is provided. The patient information is determined from sensor data of a mobile telephone sensor of a mobile telephone, such as a smartphone, coupled motionally to the patient, at least in one direction of movement.
