fig1 shows a preferred embodiment for the table . the table comprises a supporting platform 10 having a back end and a front end for supporting the patient &# 39 ; s legs and torso , respectively . the patient lies face down on the table , slightly off center , and places a breast inside the cavity 11 present in the front end of the supporting platform 10 . the breast is pendantly suspended within the cavity 11 . the table has a lateral depression for allowing the arm and shoulder adjacent to the breast to extend over the table . in the embodiment shown in fig1 , the cavity is substantially pear - shaped . that is to mean that the cavity comprises a wide and a narrow portion , such that the wide portion is for the breast to be suspended therethrough and the narrow portion is for the axilla region adjacent to the breast to be suspended therethrough . the shape of the cavity is such that a maximum possible volume of tissue can be exposed below the table . this way , access to the regions of interest is facilitated . the table shown in fig1 can be used to perform a medical procedure on a left or a right breast . the cavity is present in a disc plate 12 in the front end of the supporting platform 10 . for imaging of the left breast , the cavity 11 must be rotated such that the narrow portion is facing towards the left side of the table in order to receive the left axilla region of the patient . the rotation of the disc 12 can be done manually or remotely with a set of controls . the headrest 13 must also be moved such that the space provided for the arm of the patient is on the left side of the table . as can be seen from the figure , the headrest 13 is independent of the supporting platform 10 and can be slid to the opposite side . this can also be done either manually or remotely with a set of controls . in optical imaging , it is desirable to obtain a simple geometry of the object being imaged such that mathematical algorithms can be used to produce the actual image . one way to do this is to use a pair of parallel plates that compress the breast into a rectangular slab and produce a parallelepiped . the plates are also used to stabilize the breast and prevent motion during the imaging . when stabilizing plates are used to compress the breasts and scan an image , a circular shape is ideal for the cavity when the compression is at 0 ° and 90 ° with respect to the table . however , a pear - shaped or oval cavity is preferred when compressing the breast at around 45 ° with respect to the table in order to properly access the tissue in the axilla region . therefore , the disc plate 12 seen in fig1 is removable and can be replaced by a similar disc plate with a cavity that is circular . furthermore , the circular cavities may vary in size to accommodate breasts of different sizes . an armrest 14 can also be seen in the figure . the armrest 14 is below the level of the table and serves to support the elbow and forearm of the patient that is adjacent to the breast suspended in the cavity 11 . the armrest 14 is adjustable in height to accommodate patients of different sizes and place the shoulder at the ideal level such that the patient is comfortable enough to remain in a fixed position for a substantially long amount of time . the supporting platform 10 is also slightly inclined such that the legs and feet are at a lower level than the head and torso . this is also for patient comfort and provides the patient with a better sense of stability in the prone position . fig2 shows an alternative embodiment to providing a space for the arm on a left and a right side of the table . a supporting platform 10 is still present to support the legs and torso of the patient . however , a large disc 15 is engaged into the supporting platform 10 . within this large disc 15 is a smaller disc 16 with the cavity 11 for the breast . the larger disc 15 rotates such that the opening for the breast is on the left or the right side of the table , depending on the breast in question . the cavity 11 for the breast is closer to the side than in the previous embodiment , shown in fig1 . the design of the smaller disc 16 is such that the breast can be scanned or imaged in at least three directions . two parallel , vertical , stabilizing plates compress the breast at 0 ° ( the plates move along the axes of the table ), 90 ° ( the plates move perpendicular to the axes of the table ), and 45 ° ( the plates move diagonally ). the plates , which are seen as two compression members in the figure , form a rectangular cavity and can accommodate breasts of varying sizes . the two plates can move inwards for compression , as well as up , down , and rotate with respect to the rest of the platform . the smaller disc 16 is formed of at least two separate pieces that surround the cavity 11 . one of the pieces can be removed to leave a space for the axilla and underarm region , providing a lateral depression on a left or a right side of the table , depending on the position of the larger disc 15 . an armrest 14 is also present to support the forearm and elbow when the axilla region is exposed through the cavity 11 . the design of the larger disc 15 is possible without the smaller disc 16 within it . a regular cavity is present within the larger disc 15 , the cavity being fixed in size and shape . this embodiment can be used for biopsies , wherein it is unnecessary to compress the breast at different angles because images are not being taken of the breast . the biopsy equipment can easily be placed underneath the table and used in conjunction with it . alternatively , a pear - shaped cavity may be present in the larger disc . the cavity is to be angled at approximately 45 ° below the horizontal axis of the disc . when the disc is rotated , the cavity is still angled at approximately 45 ° of the horizontal axis , but on the opposite side of the table . in this case , compression plates may be independent from the table and be provided beneath the table . a space on adjacent to the cavity is to be provided for the arm if the smaller disc plate is not within the larger disc plate . fig3 is a preferred embodiment of the apparatus in accordance with the present invention . from the figure , it can be seen that the supporting platform is not flat , but instead comprises concave and convex curves that are specially designed to increase patient comfort . the central area of the supporting platform is upwardly winged on each side so as to nest the patient within the curve formed by the wings 17 . this creates a sensation of security and eliminates the possibility of rolling off the table . steps 18 are adjacent to the supporting platform to facilitate mounting of the patient . a banister 19 and handles 20 are also provided to facilitate the mounting and allow the patient to ease herself onto the table comfortably . fig4 corresponds to a flow chart according to the method of the present invention of positioning a patient on a table for a medical procedure on a breast . the first step is to place the patient face down on the supporting platform 30 . a cavity is provided for the breast and axilla region to be pendantly suspended therethrough 32 . an arm and shoulder of the patient adjacent to the breast is extended over the table , wherein a left arm and shoulder is extended over the table on a left side of the cavity when a left breast is in the cavity and a right arm and shoulder is extended over the right side of the table when a right breast is in the cavity 34 . the height of the arm and shoulder is adjusted 36 by adjusting the position of the elbow and forearm on an armrest which is provided below the supporting platform . the arm can be supported by being extended upwards and bent inwards towards the head or simply by being extended parallel to the body . the feet of the patient are also adjusted in height 38 by elevating them using a footrest . the head is then adjusted in height 40 on a headrest . when placing the patient face down on the supporting platform 30 , the patient may be placed in an inclined position such that the feet are lower towards the ground than the upper body . the cavity provided may be substantially pear - shaped such that a narrower portion is for the axilla region and a larger portion is for the breast . this pear - shaped cavity is rotated from a left side of the table to a right side of the table , and vice - versa , such that the narrower portion is always angled towards the outer edge of the table , whether a left or a right breast is in the cavity . it will be understood that numerous modifications thereto will appear to those skilled in the art . accordingly , the above description and accompanying drawings should be taken as illustrative of the invention and not in a limiting sense . it will further be understood that it is intended to cover any variations , uses , or adaptations of the invention following , in general , the principles of the invention and including such departures from the present disclosure as come within known or customary practice within the art to which the invention pertains and as may be applied to the essential features herein before set forth , and as follows in the scope of the appended claims .
